This survey was conducted to document the distribution, market potential, medicinal properties, and conservation status of wild food plants (WFPs) which are consumed by local communities of poor socioeconomic background, residing near the Pakistan-Afghan border. Data were collected via semi-structured during 2017–2020 and a total of 288 informers were interviewed in a different locality. In this survey, a total of 95 WFPs species of 39 families and 58 genera were documented. Among these WFPS, 70% of species are ethno-medicinally known. August was the peak month for the accessibility of WFPs (i.e., 17%). The most consumed parts were leaves (37%) and fruit (36%). Plant species of 36 families out of 39 were marketable and reported for the first time, which was further interrelated with taste, ethnobotanical, ethnomedicinal value, FC, and relative frequency of citation (RFC). Rhamnaceae and Rosaceae were the dominant families with the highest number of frequencies of citation (FC) and number of species. The highest FC (77) and RFC (0.267) were calculated for Ziziphus jujuba. This study presents the market potential and distribution of the WFPs for the first time in a war-affected zone. These findings would facilitate local people along the Pakistan-Afghan border and researchers to utilize WFPs to fulfill food requirements. We suggest that further pharmacological and biological assessments of these plants can contribute to economic prosperity, and increase the dietary diversity of this region.

The current study was designed to assess the comparative morphology of eight olive cultivars with different geographical origins and diverse genetic backgrounds, introduced to a new climatic zone. The morphological parameters of eight (five exotic and three domestic) olive cultivars (Bari Zaitoon-1, Bari Zaitoon-2, Favolosa (FS-17), Koroneiki, Balkasar, Ottobratica, Leccino, and Arbequina) were compared at the experimental area of the Department of Botany, The Islamia University of Bahawalpur, Pakistan (29°24′0″ North, 71°41′0″ East, 401–421 feet above sea level). Plant height, number of leaves/15 cm shoot, leaf size characteristics (leaf length, leaf width, leaf area, and length/width ratio), leaf shape characteristics (margin, leaf axil, base, and apex angles), leaf pigments (Chlorophyll a, Chlorophyll b, total chlorophyll contents, and carotenoids), phyllotaxy, and leaf color and venation were recorded. The highest plant height (28 cm) was obtained by Bari Zaitoon-2 followed by Bari Zaitoon-1 (24 cm), both of which are domestic cultivar of Pakistan, while the shortest height (5 cm) was obtained by Koroneiki. Leccino displayed the highest average number of leaves (17.8) on main shoot, followed by BARI-2 (16.4) and the lowest score was from Balkasar (10.4). Leaf area ranged from 5.66 cm2 (Bari Zaitoon-1) to 3.08 cm2 (Koroneiki). The longest leaf length (5.74 cm) was found in Bari Zaitoon-1 and the shortest (4.04 cm) in Koroneiki, while the broadest leaves were found in Leccino (1.54 cm) and the narrowest (1.12 cm) in Koroneiki. Bari Zaitoon-2 led in leaf length to width ratio (4.058) followed by Bari Zaitoon-1 (3.772) with small lanceolate leaves hardly reaching the value of 4, with the lowest value illustrated by Leccino. The total chloroplast pigments were highest in FS-17 followed by Bari Zaitoon-1 and Bari Zaitoon-2, while the lowest was in Arbequina. Chlorophyll a was highest in Bari Zaitoon-1 followed by FS-17 and Balkasar, with the lowest rate in Arbequina. Chlorophyll b content of FS-17 was the highest whereas the Chlorophyll b and total chlorophyll contents in Arbequina were the lowest of all the cultivars. The highest value of total carotenoids was found in Balkasar followed by FS-17 with the lowest value in Arbequina. The phyllotaxy was categorized into three types, i.e., alternate, opposite, and whorled. The combination of two or more types was usually observed on the same branch. The whorl of four leaves was also present in rare cases. Leaf venation was both pinnate and reticulate. The leaf base of most (four) of the olive cultivars, i.e., Arbequina, Balkasar, Leccino and FS-17, were cuneate having acute, rounded, apiculate, and cuspidate leaf tips, respectively. The findings revealed remarkable variations in olive morphology, especially in the leaves and a successful record of the preliminary data of olive cultivars from the study area was made. The present research demonstrated that local olive cultivars have unique characteristics that differentiate them from imported cultivars. Thus, local cultivars provide novel genetic resources that should be conserved.

The Begomovirus genus of the family Geminiviridae comprises the largest group of geminiviruses. Begomoviruses are transmitted by the whitefly complex (Bemisia tabaci) and infect dicotyledonous plants in tropical and subtropical regions. The list of begomoviruses is continuously increasing as a result of improvements in the methods for identification, especially from weed plants, which are considered a source of new viruses and reservoirs of economically important viruses but are often neglected during diversity studies. Lathyrus aphaca L. weed plants (yellow-flowered pea) with varicose veins and discoloration of the leaves were found. Amplified genomic DNA through rolling circular amplification was subjected to PCR analysis for the detection of the viral genome and associated DNA-satellites (alphasatellites and betasatellites). A full-length sequence (2.8 kb) of a monopartite begomovirus clone was determined; however, we could not find any associated DNA satellites. The amplified full-length clone of Rose leaf curl virus (RoLCuV) reserved all the characteristics and features of an Old World (OW) monopartite begomovirus. Furthermore, it is the first time it has been reported from a new weed host, yellow-flowered pea. Rolling circle amplification and polymerase chain reaction analysis of associated DNA satellites, alphasatellite, and betasatellite, were frequently accomplished but unable to amplify from the begomovirus-infected samples, indicating the presence of only monopartite Old World begomovirus. It is observed that RoLCuV has the capability to infect different hosts individually without the assistance of any DNA satellite component. Recombination in viruses is also a source of begomovirus infection in different hosts.

Garam Chashma valley is a mountainous valley situated in the Hindukush mountain range in Pakistan. This area is blessed with rich and diverse medicinal flora extensively utilized by the local community to cure health issues. The present article aims to explore and document the indigenous traditional knowledge about wild plants and their curative properties. This survey was carried out during April 2018 to September 2019. Data was collected from 153 indigenous people through semi structure questionnaire, group discussion, field survey and formal talks with elder people. Quantitative analysis of recorded data was obtained by applying quantitative indices like Frequency of Citation (FC) Use Reports (UR), Family Use Value (FUV), Informant Consensus Factor (ICF), Use Value (UV) and Relative Frequency of Citation (RFC). About 83 plant taxa belonging to 36 different families were recorded for the treatment of 95 different disorders grouped into sixteen disease categories. Herbs were the most leading plant habit (81.9%) and dried plant material (51.8%) usually preferred for therapeutics uses. Among families Asteraceae (16.86%) was recorded as major taxon with highest number of species followed by Lamiaceae (12.06%). Leaves 33% were recorded most abundantly used plant part followed by flowers (17%). Regarding to formulations, decoction (39.3%) and powder (17.1%) were recorded most frequent mode of preparation while oral intake (78%) was most preferred administration route. About (40%) plants species were utilized to treat Gastrointestinal diseases (GIT) disorders. Informant consensus revealed that Gastrointestinal disorders and Dermatological disorders were top ranked ailments categories with 0.94 consensus. The current study imparted that medicinal plants are still used by the indigenous communities of Garam Chashma valley, district lower Chitral, Pakistan. Thus, this investigation provides basis for the conservation of medicinal flora in the area. Medicinal plants (MPs) having high value of FC, RFC, UV, FUV, FL and ICF should be further study for phytochemistry and ethnopharmacology to evaluate novel active ingredients for new drugs discovery.

Populists are dominating the world's political situation. The election campaign of Donald Trump in the United States, the emergence of right-wing populist parties in Eastern Europe, and the popularity of Narendra Modi ofIndia prove that we live in a populist world. Populism has also returned to Pakistan as cricketer-turning politician Imran Khan's popularity was attributed to a massive publicity campaign. This article aims to evaluate the populist coverage of Pakistan’s political parties in media. This research study aims to answer the question of which political party shares more populist views, in what form they share it, and who the targets of these populist views are. Therese archer has utilized the “Quantitative Content Analysis” as a research method to answer the outstanding research questions. The news coverage of the two leading English-language newspapers of Pakistan, namely Dawn and The News International, has been studied. A total of 278 news stories we reexamined during the month of the 2018 elections. The findings support that Pakistan Tahreek-e-Insaf was the most populist party and the Shariffamily/PMLN was the prime target of anti-elitist views shared by PTI.Findings also support that The News International gave more coverage to populist narratives than Dawn.

The genus Sophora (Fabaceae) is one of the taxonomically challenging genera with high economic and medical values. In this study, the pollen morphology of 43 samples of 27 species, 4 subspecies, and 4 varieties of the genus Sophora and 3 closely related genera was examined using scanning electron microscopy to evaluate the pollen diversity of the genus and its taxonomic significance. Pollen grains of the studied species were tricolporate (rarely six-aperture), and pollen shape varied from suboblate, spheroidal, subprolate to prolate. Echinate external ornamentation was reported for the first time in some species of the genus. Aperture membrane ornamentation and outline in a polar/equatorial view were described for the first time in the genus. Principal component analysis was used to understand the relationship and discrimination between the species and the genera, with six components accounting for 79.92% of the total variance. Taxonomic keys based on pollen morphology were also constructed to easily identify the taxa of the genus through palynological characteristics. Results showed that pollen morphology alone is not sufficient to elucidate or reconstruct taxonomic relationships within the genus Sophora, but palynological assessments can provide some useful information for identifying taxonomically problematic taxa.

The subtribe Loliinae is one of the largest subtribes of Poeae with about 600 species. Festuca is a large genus with close relations to other genera as Lolium, Castellia, and Vulpia. The taxonomic history of the Festuca-Lolium species group is very complicated. The polyploidy and hybridization make it more confusing. Due to the morphological similarities between genera identification is very difficult, the aim of the present study is to provide the taxonomic characters for the delimitation of the taxa of subtribe Loliinae. We used scanning electron microscopy (SEM) techniques for the evaluation of the lemma and palea surface micromorphology for 33 species of this subtribe. Multivariate statistical analysis was used to show the species groupings. Factor analysis based on the principal component analysis showed the diagnostic importance of each of the characters. The lemma and palea epidermal patterns of Castellia, Festuca, and Lolium were examined, and results revealed that Lolium and Vulpia sensu lato species made separate groups nested in the Festuca clusters. The length of the long cell of the lemma, prickle in the lemma and palea, the wall shape of long cells of the lemma, wax type, silica bodies of lemma and palea, and the short cells in palea were important diagnostic characters for the species studied. The measured and evaluated set of lemma and palea micromorphological features was unable to provide the delimitation of the Festuca genus as subgeneric or sectional level. Present observations illustrated a heterogeneous assemblage as Festuca that needs further study for delimitation.

In this research, the fruits and seeds' surface morphological features and their taxonomic significance were determined. Additionally, useful traits for delimitation of taxa of Rosa sericea complex were studied. In this research, three taxa of the complex R. sericea, R. omeiensis, and R. sikangensis have been studied. A total of 41 populations and 130 specimens of seeds, and 35 populations and 168 specimens of fruits from 10 different geographical regions of southwest China have been examined. The surface micro-morphological characters of the seeds have been studied through scanning electron microscopy to distinguish important characteristics of the complex taxa. Forty-four different qualitative and quantitative characteristics were observed. Principal component analysis was used to simplify and elucidate the relationship between the studied characters of different population based on the morphology of fruits and seeds' features. Moreover, the numerical taxonomic characters and their variation with elevation have been studied in these species. The most interesting characters observed on the surface of the seeds were stomata, and trichomes, for which density was more at the dorsal and ventral parts, while rarely present on the lateral parts. The fruits and seeds' surface morphology of the studied species was complicated and some variation in the characters, that is, persistent calyx shape, the shape of fruits and seeds, stomata shape, and trichomes size were found significant for delimitation of taxa in the complex. The purpose of this study is to identify the taxa of R. sericea complex based on fruits and seeds' morphological characters, and identification keys.

In this research, 25 medicinally used Lamiaceae species belonging to 20 genera have been studied and identified for the nine disorders. We used scanning electron microscopy (SEM) for qualitative and quantitative morphological character identification. The micromorphological characters observed here were important for distinguishing the studied taxa. The highest medicinal values were reported for Vitex negundo and Scutellaria baicalensis for all considered categories except urinary and otorhinolaryngology disorders. The foliar epidermal anatomical characteristics revealed that the micromorphological features of the Lamiaceae species provide taxonomically significant and accurate identification information to delimitate the family species. Moreover, we focused on both qualitative (epidermal cell shape, stomata type, stomatal pore shape, subsidiary cell shape, glandular trichomes, and non-glandular trichome shape) as well as quantitative features (epidermal cell size, stomata size, stomatal pore size, subsidiary cell size, and trichomes size). The trichomes diversity was different in most species' on adaxial and abaxial surfaces. In most species, anomocytic stomata were observed, but other types such as diacytic, paracytic, and tetracytic type stomata were also examined. The diverse pattern of anatomical characters suggests that the studied taxa provide insight evidence for the taxonomic observation of the Traditional Chinese Medicinal plants from the Lamiaceae. This work sets an avenue for future research and taxonomic exploration of medicinal flora through microscopic investigations. RESEARCH HIGHLIGHTS: This research offers a thorough microscopic identification of the family Lamiaceae. Taxonomic information on the trichome characters and types for the accurate authentication. Qualitative and quantitative characterization of 25 medicinally used Lamiaceae taxa.

Lolium rigidum (Poaceae) is important forage and weed species grown in different habitats of Iran. Rigid ryegrass originated from the Mediterranean region. They are very resistant to common herbicides. To investigate the genetic variability of L. rigidum, we studied 81 individuals of 18 natural populations from Iran; four ISSR and four SCoT primers were used. These are reproducible and highly polymorphic markers. We examined their gene flow and genetic variation. Genetic diversity among and within populations was determined through different methods. The Mantel test indicated a significant correlation between these populations’ genetic distance and geographical distance and a high correlation between ISSR and SCoT markers. Analyses of molecular variance (AMOVA) produced high genetic differences among the studied populations for both markers. Structure analysis showed population genetic stratification and identified three genetic groups through ISSR molecular markers for L. rigidum in Iran and indicated restricted gene flow. The current investigation revealed the productivity of ISSR and SCoT molecular markers in evaluating genetic variation and grouping of wild populations of L. rigidum and provides detailed data concerning the genetic structure of its populations. The present finding provided useful information for further conservation, selection, and breeding plans.

Lamioideae comprised the second-largest subfamily in Lamiaceae. Although considerable progress has recently been made in the taxonomic study of Lamioideae, the subfamily remains one of the most poorly investigated subfamily in Lamiaceae. Therefore, the present study was designed with the aim to document the pollen micromorphology of some selected Lamioideae taxa and its taxonomic significance from Pakistan. Pollen micromorphological features were observed using scanning electron microscopy. The pollen grains are monad, tricolpate, radially/bilateral symmetrical. The pollen grains were small to medium-sized having oblate, oblate/subspheroidal, and subspheroidal shape. Exine sculpturing was observed as reticulate, microreticulate, and bireticulate. The colpus surface ornamentation was found as verrucate, gemmate, scabrate, and psilate. There was a considerable variation between the species in the micromorphology, that is, the coarseness of the reticulum, thickness of the muri comprising the reticulum and the number of secondary lumina per primary lumen. Hence, this study documented the pollen morphology of some selected taxa of the subfamily Lamioideae from Pakistan and strengthens the taxonomic identification of subfamily based on pollen characters, which helps in the correct identification, discrimination of the species of Lamioideae at generic and species level.

Medicinal plants have been used worldwide for population control since ancient times. Today, population growth is one of the burning issues in the world. The main purpose of this research is to record and investigate contraceptive uses of medicinal plants in order to control population growth in Pakistan and in the world through cheaper and safer methods. Field trips were carried out from November 2015 to March 2017. These data were collected during field surveys and interviews from traditional therapists and from the local of the District Shangla. The information gathered was quantitatively analysed through relative frequency of citation (RFC), disease consensus index (DCI) and Jaccard index (JI). The results showed that a total of 48 plant species belonging to 40 genera and 26 families were used by the local communities of the study area as male contraceptives. A detailed study of these reported plants species was done by investigating local name, part used, family name and habitat, mode of utilization etc. This study documented some important medicinal plants for the use and control of male contraception and will attract the researcher's interest for clinical trials, which could be of great scientific support to the society.

The present research work was carried out to conduct concordance between the molecular data and the phylogenetic relationship between the selected species of Lamiaceae. We studied 34 species collected from various phytogeographical areas of Pakistan. Molecular DNA was isolated from fresh leaf specimens of the selected taxa. The rps14 gene was amplified for the isolation of DNA sequencing and the amplified products were sequenced and analyzed for phylogenetic analysis. The sequenced products were analyzed using bioinformatics tools such as MEGA7, I-TASSER (Iterative Threading Assembly Refinement) and SAVES (The Structure Analysis and Verification Server). ExPASY translate tool was used for the translation of nucleotide sequences to amino acid sequences. Phlomis cashmeriana with Origanum vulgare, and Lamium album with Lamium amplexicaul showed a close relationship in both phylogenetic trees with well-represented bootstrap (BS) values. The pairwise distance ranged from 0.013 to 0.19 with an overall mean distance of 0.068 was also observed. I-TASSER software was utilized to predict the 3D protein structures followed by stereochemical analysis. Based on the present finding it is determined that the rps14 gene would be used as a DNA barcode for the identification of plant taxa. Additionally, it is needed for the development of additional reliable molecular markers to resolve the systematics issues in the family Lamiaceae.

In all over the world, herbal drugs are usually adulterated with similar species or varieties due to incorrect identification. Most of herbal products devoid purity and quality, therefore an attempt was carried out to identify plant species and authenticate its herbal drug products from Mentha suaveolens. Microscopy tools provide an excellent platform to identify plants at species level. In this study, microscopic and pharmacokinetic parameters of M. suaveolens were observed. Plant species were collected from high diverse areas of Northern Pakistan. Macro and micro-morphology including palynology and anatomical features were analyzed to study M. suaveolens. Species characteristics were studied, while implementing microscopic techniques for the delimitation and identification of the species. Traditionally Mentha species are used to cure several diseases that is, digestive disorders, respiratory disorders. Micromorphology (stem, leaves, flowers structure, length etc.), palynology (shape, size of pollen etc.), and anatomical characters (types of stomata, epidermal cell shape, and trichomes) were studied. Micromorphology and anatomical characters were of great interest and significance to discuss the taxonomy of the species. Taxonomic characters were studied to characterize and authenticate the species. The aim of the present study is to observe in detail the taxonomic identification of the species in term of morphology, palynology, and foliar epidermal anatomy for the correct identification along with their medicinal uses in the area.

Currently, prevention and control of the coronavirus disease pneumonia epidemic situation are grim globally. To cope with total sheer carriers and patients of COVID-19 requires intensive medical support and adjunctive therapies to overcome the disease. The epidemic can be controlled with the help of both, disease suppression via community health measures and adjunctive therapies for patients suffering from infection. Till date, we do not have any proper anti-COVID-19 therapy. In order to achieve the overall realization of this pandemic, there is a need to identify treatments depending upon their direct or indirect targets; like inhibition of polyprotein synthesis, transmembrane serine protease, inhibition of viral entry and endocytosis. This could be possible by turning the focus in the direction towards the development of numerous tentative drugs, particularly in the severe to badly ill. Though, majority of these off-label adjunctive medicines are being inspected in a lot of clinical trials at different stages, scientific organizations have endeavored to elucidate the situation where these adjunctive drugs might be practiced as off-label, open- label or compassionate. Our review compiles the adjunctive therapies adopted in COVID-19 infected patients according to clinical severity in conjugation with practicing recommendations from existing guidance rules issued by global professional bodies in healthcare.

The bactericidal effects of nanomaterials play an essential role in cytoplasmic leakage, leading to bacterial cell death. In this study, silver nanoparticles (AgNPs) were synthesized using a fungal extract of Aspergillus fumigatus (A. fumigatus). The physicochemical properties of the bare and myco-synthesized AgNPs (MS-AgNPs) were examined by X-ray diffraction (XRD), Fourier transform infrared (FT-IR) spectroscopy, ultraviolet–visible (UV–vis) spectroscopy, scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDX), and transmission electron microscopy (TEM). XRD revealed the crystalline structure of the prepared NPs. The FTIR spectrum of the MS-AgNPs revealed the presence of the stretching vibrations of hydroxyl (−OH) and carbonyl groups (C=O). The UV results showed absorption from 450 nm to 590 nm, confirming the synthesis of the AgNPs. SEM and TEM showed rough cubic shapes (spheres), 20–60 nm in size, while EDX confirmed the presence of 60% Ag in the sample. The MS-AgNPs revealed the highest antibacterial activity against Staphylococcus aureus, with a zone of inhibition of 18.21 ± 2.1 mm, followed by Shigella dysenteriae and Salmonella typhi. The bimetallic-AgNPs played a vital role in cell membrane damage and the release of cellular contents, specifically nucleic acids and proteins. These results suggest that MS-AgNPs have promising antimicrobial capabilities and might be beneficial for an extensive array of biological applications.

In present study, 18 plant species belonging to 7 genera of the family Convolvulaceae has been investigated by using the light microscope for foliar epidermal anatomy. Despite the medicinal importance of family Convolvulaceae, there is no evidence regarding the secretory structure and their effect of environmental conditions on their density is unknown. The aim of the study was to describe the morphology of these secretory structures and to estimate the hypothesis that glandular trichomes density decreases with increased aridity. Foliar micromorphology of Convolvulaceous taxa, gathered from arid parts of Northern Punjab Pakistan, was first time conducted with an aim to utilize this information as an aid in plant taxonomy. Significant diversity was observed in both qualitative and quantitative characteristics using light microscopy. Variations were observed in stomatal number, size, guard cells shape, epidermal cell number, subsidiary cells, and trichomes. Unique ornamentation was observed in trichomes diversity. A taxonomic key was prepared for the identification of species. The main goal of this study was to describe the morphology of glandular trichomes and to estimate the hypothesis that glandular trichomes density decreases with increased aridity. Based on these findings, Light microscopy of foliar epidermal features can be of special interest for taxonomists in the identification of complex taxa. Studied taxa were also separated from each other by using Cluster Analysis (MVSP ver.3.22). Statistical analysis by using the Software XLSTAT exhibited that some anatomical features are the main characteristics in the identification of the taxa. Principal component analyses (PCA) used as a statistical tool for data analyses that show the importance of these characteristics for the characterization and identification of the family Convolvulaceae in an arid land. The study shows many novel characters that provide baseline information about trichome diversity in relation to aridity for future taxonomist.

The resurrection plant species, termed desiccation-tolerant plants have evolved remarkable ability to withstand extreme dehydration and rapid rehydration of vegetative tissue without damage. Pteridophytes include almost 70 desiccation tolerant species, and there is limited information of vegetative desiccation tolerance in ferns. A field examination of the representatives of the ferns flora of the Northern Pakistan disclosed 5 ferns species belonging to 2 genera with foliage which can revive after dehydration. These species are Asplenium dalhousiae, Asplenium ceterach, Cheilanthes acrostica, Cheilanthes bicolor, and Cheilanthes nitidula. We undertook a comprehensive leaf micromorphological investigation in all the five resurrection fern species. The study were accomplished using light microscopy (LM) and scanning electron microscopy (SEM). The detailed investigation of adaxial and abaxial leaf surfaces revealed species specific variation in the size and number of epidermal cells, size of stomata, and stomatal pore, stomatal density, and stomatal index and other foliar micromorphological features. In all studied species, adaxial surface lack stomata, i.e., all species are hypostomatic, stomata is polocytic, and epidermal cells shape in all species on both surface is similar, and are irregular shaped. The quantified leaf micromorphological traits are discussed in order to detect their possible role in the desiccation tolerance of resurrection fern species.

Palynological characters of 18 species belonging to seven genera of the traditional subfamily Alsinoideae including Arenaria, Cerastium, Eremogone, Lepyrodiclis, Minuartia, Sabulina and Stellaria were studied in detail using light and scanning electron microscopy. Pollen grains of subfamily Alsinoideae are subspheroidal or prolate, pantoporate and 20.04 to 51.4 µm in size, prominent and sunken apertures uniformly distributed on the pollen surface. Two types of pollen grain ornamentation were observed, i.e. microechinate-punctate or microechinate-perforate. Echini are present on the surface of the pollen of all investigated species with medium, dense, or sparse echinodensity. These species exhibit variation in polar view, equatorial diameter, number of apertures, exine thickness, diameter of pore, appendages per pore, pore ornamentation, echini arrangement, echinidensity and shape of pollen. Based on qualitative characters, a dichotomous key has been developed for quick and easy identification. The...

Foliar and stem epidermal anatomical features of the tribe Cynoglosseae have been studied in detail for the taxonomic identification using light microscopy (LM) and scanning electron microscopic (SEM) techniques. A comparative study was conducted on different plant parts (leaf and stem epidermal anatomy) of 25 species belonging to eight genera of the tribe Cynoglosseae (Boraginaceae) collected from different phytogeographical regions of Iran for the first time. Different qualitative and quantitative characteristics were observed in detail using LM and SEM. Results showed that although generally the stem and leaf anatomical traits were similar, but some diagnostic features were examined for distinguishing the closely related genera in the tribe. The ratio of cortex/diameter of stem and phloem/xylem, the average row number of collenchyma, palisade and spongy cells, structure of trichomes, type of indumentum and palisade arrangement were found taxonomically important. The anatomical characters were statistically analyzed using cluster analysis and principal component analysis. The study found that stem and leaf eccentrics are variable in the genus but constant within species of the same genus. Most species had typical isobilateral leaves, but some showed an incipient dorsoventrally symmetry with a layer of abaxial palisade tissue. Eglandular trichomes were observed found in all the studied species, which were recognized based on structure and function. In present study some novel characters have been observed which are of great interest to the taxonomist for the correct identification some genera delimitations. The characters studied here are of less taxonomic value and delimitating at species level.

Foliar epidermal features were based on the micromorphology of trichomes types, epidermal cells and stomatal complex. Even though each feature has its own limited taxonomic value but collectively these characteristics may be systematically important especially for the discrimination and identification of complex and problematic taxa. The systematics significance of nonglandular (NGTs) and glandular trichomes (GTs), stomatal complex and epidermal cells of Lamiaceous flora were analyzed by using the light microscopy (LM) and scanning electron microscopy (SEM). Variations on the observed epidermal appendages were divided into two basic types: glandular and nonglandular. GTs can be divided into subtypes: sessile capitate, subsessile capitate, and barrel and sunken. NGTs were also divided into subtypes: dendritic, stellate, conical, falcate, simple and 1-6 cells long having granulate and smooth surface ornamentation. NGTs were the most dominant features of both adaxial and abaxial surfaces of all observed taxa. Vitex negundo, Isodon rugosus, Colebrookea oppositifolia, and Marrubium vulgare could be demarked because of their twisted like appearance of NGTs at the abaxial surface. The Lamiaceae had both hypostomatic and amphistomatic leaf. Stomata were observed as diacytic, anisocytic, and anomocytic. Epidermal cells were found to be irregular, isodiametric, and rectangular. Based on these characters a taxonomic key was developed to delimit the closely related taxa. Distribution and morphology of the foliar epidermal trichomes through SEM highlight an important taxonomic tool used by the taxonomists as an aid to the correct identification of problematic Lamiaceae taxa.

The pollen morphology of 11 salt tolerant plant species of family Amaranthaceae from the salt range of Northern Punjab, Pakistan has been studied. The palyno-morphological characters were examined using light and scanning electron microscope. The examined all salt tolerant species have a slight difference in size but have similarity in shape, pore ornamentation, and polarity. The observed morphological characters of pollen grains were pollen symmetry, size, shape, pore ornamentation, pore size, number of pores, exine thickness, polar and equatorial diameter and, P/E ratio. Apolar type of pollens has been observed in all species. Shape of pollens was spheroidal. Exine sculpturing of pollen grains was scabrate (six spp), microechinate (four spp), and microechinate-scabrate (one spp). Different pori numbers were observed in different species. The pantoporate aperturate and sunken pore ornamentation have been reported in all species. A pollen taxonomic key was developed using examined morphological characters for the accurate identification of halophytic taxa. The high fertility and low sterility of pollens confirmed that the selected halophytes are well-established in the salt region. The findings highlight the taxonomic significance of pollen morphology in correct identification and differentiation of salt tolerant plant species.
