The water lily clade represents the second earliest diverging branch of angiosperms. Most of its species belong to Nymphaeaceae, whose dominant clade (the “core Nymphaeaceae”) comprises the genera Barclaya, Euryale, Nymphaea, and Victora. Despite previous molecular phylogenetic studies on the core Nymphaeaceae, various aspects of their evolutionary relationships have remained unresolved. Among these unresolved questions are (i) the potential sister relationship of Euryale and Victoria to the subgenera Hydrocallis and Lotos of Nymphaea, which would render Nymphaea paraphyletic, (ii) the potential sister relationship of the type subgenus of Nymphaea to all other species of the genus, and (iii) the unclear relationships within the subgenera Brachyceras, Hydrocallis, and Nymphaea of Nymphaea. New molecular phylogenetic studies on the core Nymphaeaceae need to accommodate the idiosyncrasies of the non-coding plastome regions, as most of the DNA sequence variability and, by extension, phylogenetic information between the water lily genomes is located in the length-variable introns and intergenic spacers. For example, new studies must emphasize correct, motif-based DNA sequence alignments of intron and intergenic spacer regions before phylogenetic tree reconstruction. In this study, we revisit the phylogenetic history of the core Nymphaeaceae by employing such an approach. Specifically, we use a plastid phylogenomics analysis strategy in which the coding and non-coding partitions of the plastome are separated by region and undergo an automatic as well as a manual DNA sequence alignment. Our approach allows us to increase the reliability of the character base compared to the default practice of aligning complete plastomes through automated algorithms. It produces significantly different phylogenetic tree reconstructions for several of the regions under study. The results of these reconstructions indicate that Nymphaea is paraphyletic in its current circumscription, that each of the five subgenera of Nymphaea is monophyletic, and that the type subgenus is sister to all other subgenera of Nymphaea. Our results also clarify many relationships within the Nymphaea subgenera Brachyceras, Hydrocallis, and Nymphaea. Finally, we discuss whether the phylogenetic reconstructions received through our approach are in line with morphological evidence.

Most plastid genome sequences are assembled from short-read whole-genome sequencing data, yet the impact that sequencing coverage and the choice of assembly software can have on the accuracy of the resulting assemblies is poorly understood. In this study, we test the impact of both factors on plastid genome assembly in the threatened and rare endemic shrub Calligonum bakuense. We aim to characterize the differences across plastid genome assemblies generated by different assembly software tools and levels of sequencing coverage and to determine if these differences are large enough to affect the phylogenetic position inferred for C. bakuensecompared to congeners. Four assembly software tools (FastPlast, GetOrganelle, IOGA, and NOVOPlasty) and seven levels of sequencing coverage across the plastid genome (original sequencing depth, 2,000x, 1,000x, 500x, 250x, 100x, and 50x) are compared in our analyses. The resulting assemblies are evaluated with regard to reproducibility, contig number, gene complement, inverted repeat length, and computation time; the impact of sequence differences on phylogenetic reconstruction is assessed. Our results show that software choice can have a considerable impact on the accuracy and reproducibility of plastid genome assembly and that GetOrganelle produces the most consistent assemblies for C. bakuense. Moreover, we demonstrate that a sequencing coverage between 500x and 100x can reduce both the sequence variability across assembly contigs and computation time. When comparing the most reliable plastid genome assemblies of C. bakuense, a sequence difference in only three nucleotide positions is detected, which is less than the difference potentially introduced through software choice. &nbsp

Scutellaria is one of the largest genera in the Lamiaceae with an estimated 400���500 species with a nearly worldwide distribution. Most species occur in the N hemisphere, with the Caucasus and the wider Irano-Turanian region housing a large number of taxa, many of them considered endemic. We present an overall phylogeny of the monophyletic genus Scutellaria based on rapidly evolving plastid regions (matK-trnK, rpl16, trnL-F). Three well-supported clades are evident, which render the currently accepted S. subg. Scutellaria paraphyletic to S. subg. Apeltanthus, which appears nested in ���clade A���, in which the African S. schweinfurthii is sister to all remaining taxa, followed by other lineages of S. subg. Scutellaria. Ancestral states of 12 morphological characters frequently used as diagnostic from subgenus to species level were reconstructed with BayesTraits. The S. orientalis group appears as a major radiation in the Caucasus area and the Irano-Turanian region that may comprise up to a quarter of the species in the genus. This radiation corresponds to a monophyletically defined S. sect. Lupulinaria, characterized by decussate inflorescences and specialized (e.g. cucullate) bracts. Our phylogenetic data present significant resolution at the species level within the S. orientalis group, indicating complex geographically centred patterns of speciation in adaptation to steppe and high mountain habitats, including multiple evolution of pinnate and tomentose leaves. The detailed infrageneric classification of Juzepczuk (1951, 1954) mostly does not reflect natural groups.

Phaeographis galeanoae L��cking, Moncada & B. Salgado-N. sp. nov. Mycobank MB 828117 (Fig. 3d). Diagnosis. Differing from Phaeographis bicolor in the very long, narrow, dendroid lirellae and the smaller ascospores. Type. COLOMBIA. Atl��ntico: Pioj��, Reserva Forestal Protectora (RFP) El Palomar; 10��45���47��� N, 75��08���56��� W, 200���600 m; 18 March 2016, R. L��cking, B. Moncada et al. 42981 (UNO, holotype; B, isotype). Description. Thallus corticolous, epiperidermal, up to 5 cm diam., continuous, light olive-green, unevenrugose, opaque; prothallus not observed. Thallus in section 80���150 ��m thick, with prosoplectenchymatous cortex and irregular photobiont layer, strongly encrusted with clusters of calcium oxalate crystals. Ascomata lirellate, radiately branched (dendroid), erumpent, 5���20 mm long, 0.2���0.3 mm broad, 0.1���0.12 mm high; disc exposed but narrow, dark brown; labia inconspicuous, visible as thin, somewhat irregular, greyish-brown line between the disc and the thalline margin; thalline margin basal to lateral, white. Excipulum prosoplectenchymatous, 20���30 ��m broad, dark brown to carbonized; hypothecium 15���30 ��m high, hyaline. Hymenium 70���80 ��m high, strongly inspersed, inspersion partially dissolving in K; paraphyses unbranched, apically smooth. Asci 70���80 �� 15���20 ��m, oblong. Ascospores 8 per ascus, 7���9(���11)-septate, 25���35 �� 6���8(���10) ��m, oblong, with thickened septa and lensshaped lumina, grey-brown, I + vine-red. Secondary chemistry: stictic acid, thallus in section with K + persistently yellow efflux. Etymology. We dedicate this beautiful new species to the memory of the late Gloria Amparo Galeano Garc��s (1958���2016), one of the foremost Colombian botanists and agronomists and internationally renowned specialist in the taxonomy of Arecaceae (palms), an important element in tropical forests including DTF (Garc��a 2016, Olivares and Balslev 2016). One of her last published papers was on the use of the bitter palm, Sabal mauritiiformis, for roofing in Pioj��, Atl��ntico (Andrade-Erazo and Galeano 2016), the municipality of the type locality of Phaeographis galeanoae. Remarks. The genus Phaeographis is currently not well-studied, but we were able to examine most of the type material of names belonging here. We found only three species with transversely septate ascospores, inspersed hymenium, dark brown to carbonized excipulum, and stictic acid chemistry. Among these, the eastern paleotropical P. circumscripta (Kremp.) Vain. [syn.: Graphis pasaniae Vain. nom. inval.] differs in the distinct, apically strongly carbonized labia, fitting the concept of Platygramme (Staiger 2002) and the smaller (15���25 �� 5���6 ��m), consistently 5-septate ascospores. Phaeographis bicolor M��ll. Arg., also an eastern paleotropical species, forms much shorter and broader, irregularly branched lirellae, and the ascospores are larger (35���45 �� 9���11 ��m). Finally, a third species also known from the eastern Paleotropics, P. concava M��ll. Arg., differs in the consistently 5-septate ascospores and the shorter, irregularly branched lirellae with sunken disc and prominent margins covered by a thallus layer. The new species is quite conspicuous due to the dendroid lirellae and strong color contrast between the olivegreen thallus and the dark brown disc and white margin of the lirellae.

Thallus corticolous, up to 2 cm diam., continuous, white-grey with a silvery shine, minutely uneven-verrucose; prothallus not observed. Thallus partially immersed in the periderm, in section 50–80 µm thick, ecorticate, dominated by the irregular photobiont layer, with large clusters of calcium oxalate crystals. Ascomata lirellate, more or less fissurine, unbranched to sparsely branched, immersederumpent, 0.5–1.5 mm long, 0.1–0.2 mm broad, 0.12–0.15 mm high; disc concealed; labia thin, entire, lighter than the thallus, along the slit with a thin, dark brown line, laterally covered by whitish thallus. Excipulum prosoplectenchymatous, 10–15 µm broad, yellowish, laterally covered by thallus including large clusters of crystals; periphysoids absent; hypothecium 10–15 µm high, light olive. Hymenium 90–100 µm high, clear; paraphyses unbranched, apically smooth. Asci 90–100 × 15–20 µm, oblong. Ascospores 8 per ascus, muriform, 15–20 × 9–12 µm, ellipsoid-oval, with thin septa and rectangular lumina, constricted at the median septum, hyaline, I–. Secondary chemistry: no sustances detected by TLC. Etymology. This new species is dedicated to Lino Olivares, one of the most knowledgeable and passionate empirical experts of the flora of the Colombian Caribbean dry forests and collaborator in the EcoSecos initiative and other conservation efforts in the region for 18 years (Castro-Vásquez et al. 2010, Rodríguez et al. 2012, Castellanos Castro and Newton 2015). ‐ Remarks. Currently, there are only two species known in Fissurina with a whitish, endoperidermal thallus, lacking substances, and muriform ascospores, namely F. alligatorensis Lendemer & R.C. Harris and F. ilicicola Lendemer & R.C. Harris (Lendemer and Harris 2014). The first agrees with the new species in thallus and ascoma morphology, as well as ascospore size, but has distoseptate, I+ strongly amyloid ascospores. The second one differs in the more distinct (hemithecioid) labia and the larger (24–32 × 12–14 µm), also distoseptate and I+ amyloid ascospores.

Secondary chemistry: no substances detected by TLC. Etymology. Graphis lurizana is dedicated to the Luriza community, who manages the Distrito Regional de Manejo Integrado (DMI) Luriza, the first protected area to be declared in the Atlántico Department (Molina-Acosta 2013). Remarks. Graphislurizana keysoutingroup 9 in the Graphis world key of Lücking et al. (2009a). There are four species in this group with large ascospores (> 80 µm), lacking secondary substances, and with elongate, prominent lirellae, namely G. acharii Fée, G. cleistomma Nyl., G. illinata Eschw., and G. subvernicosa Lücking. Graphis acharii and G. subvernicosa have (2–)4–6(–8) ascospores per ascus; in addition, in G. acharii the labia rather regularly become striate and the ascospores are longer (up to 170 µm), whereas in G. subvernicosa, the lirellae have only a basal thalline margin and the ascospores are narrower (15–20 µm broad). Graphis cleistomma and G. illinata agree with the new species in the singlespored asci; however, the first has shorter lirellae with an apically thin complete thalline margin, and larger ascospores (up to 180 × 40 µm), whereas the second has lirellae with an apically thick complete margin and slightly longer ascospores (up to 150 µm).

Secondary chemistry: stictic acid, thallus in section with K+ persistently yellow efflux. Etymology. This new species is dedicated to the Mokan��, the only indigenous community in Atl��ntico (Borda 2009, Montoya and Siegler 2010, 2011). The name is said to mean ��� those without feathers ��� in the Mokan�� language, but this interpretation is disputed (Montoya and Siegler 2010). The Mokan�� language has become extinct, but the community, which was considered near-extinct about three decades ago, is recovering its cultural traditions in a process of re-indigenization (Borda 2009). Remarks. Because of its uncarbonized excipulum, this species corresponds to the concept of the genus Hemithecium, which has now been subsumed under the genera Graphis and Allographa (L��cking and Kalb 2018). Among these two genera there are only two species with uncarbonized excipulum, small, muriform ascospores, and secondary substances: G. microsperma (Chitale, Makhija & B. O. Sharma) L��cking & Kalb from India differs in the smaller ascospores (15���20 �� 8���14 ��m) and the formation of norstictic instead of stictic acid, whereas Allographa dispersa (Redinger) L��cking & Kalb agrees in ascospore size, but also differs in the norstictic acid chemistry and the very short, prominent, white lirellae contrasting with the brownish thallus. The new species is morphologically similar to the widespread Graphis implicata F��e, which differs in the transversely septate ascospores and lack of secondary substances.

We present a first study of the diversity and community composition of lichens in seasonally dry tropical forest (DTF) remnants in the Atlántico department, Colombia. Lichens were sampled in two of the three protected areas of the department: Distrito de Manejo Integrado (DMI) Luriza and Reserva Forestal Protectora (RFP) El Palomar. The inventory revealed 61 species, including four new to science: Fissurina linoana Lücking, Moncada & G. Rodr. sp. nov., Graphis lurizana Lücking, Moncada & Celis sp. nov., G. mokanarum Lücking, Moncada & M.C. Martínez sp. nov., and Phaeographis galeanoae Lücking, Moncada & B. Salgado-N. sp. nov. Arthonia erupta and Coenogonium saepincola are new to South America, whereas thirteen species are recorded for Colombia for the first time. Further 37 species are new records for Atlántico, raising the total of species known from the department from 27 to 84. With 42 species at Luriza and 31 at El Palomar, species richness was comparable to that of other DTF sites in the Neotropics. Overlap in species composition between the two sites was remarkably low, with only twelve shared species (20 %), indicating a high level of heterogeneity. Biogeographical affinities lie with Central American DTF, which is in line with those of woody plants. These results underline the importance of the remaining fragments of DTF in Colombia in conserving partially unknown biodiversity and the necessity for their continuing conservation. RESUMEN Presentamos un primer estudio de la diversidad y composición de comunidades de líquenes en remanentes de bosque seco tropical (bs-T) en el departamento de Atlántico, Colombia. Se muestrearon líquenes en dos de las tres áreas protegidas del departamento: Distrito de Manejo Integrado (DMI) Luriza y Reserva Forestal Protectora (RFP) El Palomar. El inventario registró 61 especies, incluyendo cuatro especies nuevas para la ciencia: Fissurina linoana Lücking, Moncada & G. Rodr. sp. nov., Graphis lurizana Lücking, Moncada & Celis sp. nov., Graphis mokanarum Lücking, Moncada & M.C. Martínez sp. nov. y Phaeographis galeanoae Lücking, Moncada & B. Salgado-N. sp. nov. Arthonia erupta y Coenogonium saepincola son nuevos registros para América del Sur, mientras que trece especies son reportadas por primera vez para Colombia. Unas 37 especies adicionales son nuevos reportes para Atlántico, incrementando el total de especies conocidas para el departamento de 27 a 84. Con 42 especies en Luriza y 31 en El Palomar, la riqueza de especies fue comparable con la de otros sitios de bs-T en el Neotrópico. El traslape en la composición de especies entre los dos sitios es bajo, con solamente doce (20 %) compartidas, indicando un alto nivel de heterogeneidad. Las afinidades biogeográficas son mayores con los bs-T de Centroamérica, lo que coincide con las de plantas leñosas. Estos resultados enfatizan la importancia de los remanentes de bs-T en Colombia para la conservación de una biodiversidad poco conocida.

Note. – The type of Iresine edmonstonei that was collected by Edmonston might have been from a plant introduced by early settlers or the specimen was mislabeled to originate from Galapagos (Eliasson, 1985). The folder of I. elatior in the Willdenow herbarium (B) contains four sheets, only two of which have labels. Sheet 0 4 is the only one with a label saying “ Iresine – spec. nova”. The fact that the folder itself contains on its inside three more labels, out of the hand of Bonpland as well as Schlechtendahl (H.W. Lack, pers. comm.) is a further indication of a different origin of the sheets but also that these three labels cold not unambiguously be assigned to any of the sheets. A lectotypification is therefore warranted. The geographic origin of the specimens is unknown. The type specimen of I. laxissima is from a hermaphroditic plant and has only bisexual flowers. The name “ Rosea poeppigiana Klotzsch ” is not validly published but was listed by Seubert (1875) as a synonym of I. elatior Rich. ex Willd. There is a specimen in B (E.F. Poeppig s.n., B 10 0 242399, from Brazil, Pará) annotated with the name “ Rosea poeppigiana Kl. ”. The handwriting is clearly by J.F. Klotzsch (R. Vogt, pers. comm.). Seubert cited this name as it was often practised at the time.

Note. – No lectotypification of Iresine latifolia was made by Pedersen (1997), who also cited a wrong collector’s number (Galeotti 520) for the type. The two Galeotti specimens mentioned in the protologue are numbers 420 and 423. We have selected Galeotti 423, the sheet with barcode 0 0 0 0 0 6952501, which has the more complete label; the isolectotype could be a duplicate for which a simpler label was just written by hand. Standley (1916) erroneously made a new combination using Achyranthes calea Ibáñez as basionym, assuming that “ Iresine latifolia D. Dietr. ” was already available as a validly published name. However, as pointed out by Pedersen (1997) the name Iresine latifolia appears nowhere on p. 870 in Dietrich’s Synopsis plantarum (vol. 1, 1839), although this is cited by Moquin-Tandon (1849: 351). On the other hand, Moquin-Tandon mentiones two pages earlier (p. 349) “ Iresine latifolia = Alternanthera pulverulenta ”, which apparently is an error because Alternanthera latifolia is the next entry on p. 351 of Moquin’s treatment. No specimen of I. latifolia var. velutina could be localized at B. The existence of duplicates that could serve as lectotypes cannot be excluded as Endlich specimens are in various herbaria such as G, L and MO (electronic search so far not successful).

Note. – The Aschenborn specimen at FR that is designated as the lectotype of Iresine cassiniiformis is from the herbarium of Sebastian Schauer (see also comment in sched. by S.

The protologue cites the Aschenborn collection numbers 169, 617 and 618, none of which could be localized so far in any herbarium. Aschenborn collected in Mexico from 1839 to 1841 and sent specimens to several European herbaria (see Butzin, 1985). More than 700 specimens were deposited in Berlin, from which only a small proportion survived the destructions of the Second World War. Today, no Aschenborn specimen of I. cassiniiformis is present in B (R. Vogt, pers. comm.).

Note. – For Iresine mutisii there is no designation of any holotype nor any citation of a specimen in the protologue; but the Paris herbarium holds a specimen that might have been used as a type. It has an original label saying “Herbier donné par M. Bonpland en 1833”, which corresponds to the note published at the end of the protologue “A Mutisio cum Bonplandio communicata”. Other Mutis material in US was collected later and came there via Madrid. In order to describe I. polymorpha, Martius worked on Sellow specimens from B (H. Esser, pers. comm.) and the specimen in P has a label “Herb. Reg. Berolinense” but no material could now be located at B. The P specimen therefore is the best original material for lectotypification, assuming that the holotype in B was destroyed in the second world war. As frequently practiced at this time, no nominate variety was established by Martius (1826). Because “β effusa ” is mentioned on the original label, we treat the nominate variety as a synonym of var. effusa with the same type. No specimen exists of I. papantlana at B. It is very likely that the holotype was destroyed during the second world war, but duplicate original material with a Berlin label exists in GH. The specimen of I. pilgeri at S was labeled as the type by Suessenguth in 1934, whereas he put annotations on the B and K specimens as “co-types”. Suessenguth cites Klug 1893 as the only specimen of I. polymorpha var. verticillata f. albonervosa in the protologue. However, one year earlier, when describing I. spiculigera f. picta Suess. he mentioned the same specimen among the syntypes “desgl. 1893”. So he probably decided later that this specimen should be treated as a different entity. So far this specimen could not be localized in any herbarium. The specimen G. Klug 1756 is one of the syntypes of I. spiculigera f. picta but the locality of G. Klug 1756 is identical to G. Klug 1893. Since none of the other syntypes could so far be localized a lectotypification is premature as the correct assignment of label data in the publication needs to be checked. Eliasson (1987) did some morphometrics supporting the differentiation of var. spiculigera as a high-elevation Andean taxon. However, his study was only including material from Ecuador, so that the status of this variety within the total variation of Iresine diffusa requires further study before recognizing this and other infraspecific taxa.

The sequencing and comparison of complete plastid genomes is becoming a standard method in plant phylogenomics, and many researchers have used this approach to generate hypotheses on plant phylogenetic relationships over the past decade. Due to the widespread availability of next-generation sequencing, complete plastid genome sequences are currently being generated at breakneck pace. This trend towards massive sequencing of plastid genomes highlights the need for standardized bioinformatic workflows. In particular, documentation and dissemination of the details of genome assembly and annotation are needed, as both processes are highly sensitive to the choice of software and the precise settings used. Here, we present the procedure and results of sequencing and characterizing three complete plastid genomes of the aquatic plant genus Cabomba. We accompany our findings by a detailed description of the bioinformatic workflow employed for assembling and annotating the plastid genome sequences. Importantly, we share a total of seven software scripts for plastid genome assembly and annotation as well as for generating assembly quality statistics, enabling other researchers to evaluate and replicate our bioinformatic analyses step by step. The results of our sequencing efforts illustrate that the plastid genomes of Cabomba are highly conserved in both structure and gene content.

We aimed to (i) assess the extant genetic diversity of the riparian relict tree Pterocarya fraxinifolia across its current distribution range in the South Caucasus, including the past refugial areas Colchis and Hyrcan, and (ii) test if a separation of these areas is reflected in its phylogeographic history. Genetic diversity of natural populations was examined using nuclear microsatellite and plastid DNA markers. Spatial genetic structure was evaluated using Bayesian clustering methods and the reconstruction of plastid DNA networks. Divergence times of Colchic and Hyrcanian populations were estimated via divergence dating using a relaxed molecular clock. Allelic richness, private allelic richness, and expected heterozygosity were significantly higher in Hyrcan than in Colchis and the Greater Caucasus, and significant genetic differentiation was revealed between the two groups. Whereas only two plastid haplotypes were detected for the Colchic and Caucasian populations, the Hyrcanian populations displayed 11 different haplotypes. Significant isolation by distance was detected in Hyrcan. The most recent common ancestor of all P. fraxinifolia haplotypes was dated to a time well before a suggested glaciation period in the Caucasus during the late Pliocene (5.98 Ma [11.3–2.48 Ma HPD]). The widespread Colchic haplotype that also occurs along the southern slope of the Greater Caucasus and reaches south-eastern Azerbaijan has appeared more recently (0.24 Ma [1.41–0 Ma HPD]). This diversification pattern of Colchic haplotypes from ancient Hyrcanian haplotypes suggests a colonization of the region from south-east to north-west that predates the last glacial maximum (LGM). Natural populations of P. fraxinifolia show low-to-intermediate levels of genetic diversity and a significant decrease of diversity from Hyrcan to Colchis. However, the genetic differentiation between Colchic-Caucasian and Hyrcanian populations for nuclear markers suggests that independent gene pools existed in both areas at least since the LGM. Particular attention to conservation seems justified for the more diverse Hyrcanian populations.

Flowering pattern and seedling establishment of umbrella bamboo (Fargesia murieliae (Gamble) Yi) were studied in its native habitat, Mount Shennongjia in Central China. Here in 1996–2000, over 95% of the bamboo plants simultaneously flowered and died, extending from lower elevations to the higher mountains along the altitude and from southwest to northeast along the mountain settings. Bamboo seedlings emerged after the simultaneous flowering, achieving an average density of 5 460 seedlings· m−2 in the autumn of the year following the flowering. After a high mortality throughout the first winter, bamboo seedlings remained a stable density in following 2–4 years (1130–1230 seedlings· m−2). Seedling density positively related to the coverage of parent bamboo, but negatively to the herb layers.

Simultaneous flowering caused a gregarious dieback of umbrella bamboo (Fargesia murielae) all over the world in 1993–2000. Mountain Shennongjia in Central China’s Hubei Province is the only native home of umbrella bamboo, where it dominates the understorey of the farges fir (Abies fargesii) forest between 2 400 and 3 100 m, covering the ground for more than one century before a periodically flowering death. Data from 20 quadrats along a vegetation sequence revealed that the density, coverage, and height of umbrella bamboo negatively affected the species richness, diversity, and evenness of vascular plants in the forest. Local climax community of fir-bamboo was the poorest in species diversity, while the bamboo-free communities (i.e. shrubs and meadows) were bearing a higher species diversity. The simultaneous dieback of umbrella bamboo is an ecological release, which can periodically promote the plant diversity in the fir forest.
