Four species of Sedum genus from twentyone species of this genus present in the flora of Albania such as: litoreum, sexangulare, cepaea and rubens were analyzed comparatively for their palynomorphological characteristics versus the hispanicum specie of Albanian palynological literature sources. By the comparative study of palynomorphological features of pollen grains of analyzed species, it was noted that the pollen grains of four plants: litoreum, sexangulare, cepaea and hispanicum were three furrows and three pores, while at the pollen grains of Sedum rubens were presented as variable from three furrows and three pores to four furrows and four pores. Based on P/E ratio, the shapes of pollen grains of four species studied were varied from prolate spheroidal to oblate spheroidal, triangular or tetrangular in polar view and oblique in equatorial one. The furrows were with sharp edges and rounded end and the pores were elliptical, located within the contour of the furrow with exine remnant. The exine sculpture varied from rugulate at the pollen grains of three species: litoreum, sexangulare and hispanicum, to reticulate with uniform reticle at cepaea specie and varied from reticulate to rugulate at Sedum rubens. The biggest polar and equatorial axis dimensions were identified at Sedum rubens plant, while in terms of thickness of exine, length of furrow and mesocolpium the biggest size of pollen grains was found at hispanicum specie. While in terms of pore length appeared to be the largest at cepaea specie and for the width of furrow at Sedum litoreum plant. Regarding to the palynological indicator of pore width, it was seen that the pollen grains of three species: cepaea, rubens and litoreum had the largest dimensions simultaneously.

This article provides data on the palynological study of Pancratium maritimum L. of the Amaryllidaceae family in Albania. Pancratium is a bulbous perennial herb that is very tolerant to dry climates. It grows mainly in the coastal sandy areas of our country. The material for the study was taken fresh from the sandy area of the beaches of Durres to Divjaka, Lushnje. The processing of the material was done with the method of acetolysis and basic fuchsine. Fixation of pollen grains in microscopic preparations was done with the glycerin gelatin method. The microscopic study of the pollen grains as well as their photography was done with a microscope with X 1000 magnification. The pollen grains of these plants varied from oblate ellipsoid to oblate spheroid, heteropolar, monocolpate. The exine appears thick and has two layers. The sculpture of exine is reticulate. The palynomonomological study of these representatives is given for the first time in the literature of palynology. [ABSTRACT FROM AUTHOR]

This paper presents the morphological features of the pollen grains of Scorzonera doria and Hieracium hoppeanum and the comparison of these features with other species of the genus Scorzonera L. and Hieracium L. The material for the study was taken from the National Herbarium in Tirana. Acetolysis and basic fuchsine methods were used to study the morphological features of Scorzonera doria and Hieracium hoppeanum pollen grains. The fixing of the pollen grains is made with glycerin gelatin. A light microscope was used to take photos and study the morphological features of the pollen grains. From the study of pollen grains of Scorzonera doria and Hieracium hoppeanum, results that they are tricolporate. The shape of pollen grains according to their outline is spheroidal and oblate-spheroidal. The exine appears thick, two-layered and its ornamentation is echinolophate. [ABSTRACT FROM AUTHOR]

Palynomorphological features of the pollen grains of four honey plant: Foeniculum vulgare, Eryngium maritimum, E. campestre and Crithmum maritimum from 61 genera of Umbelliferae family present in Albania, were studied and examined by compound microscope. By the palynomorphological study of Eryngium maritimum plant compared with pollen grains of E. campestre resulted that there were similarities in the majority of their palynological features on one side, and there were differences in terms of the dimensions of pollen grains and furrows, the aperture and sporoderme features, on the other side. Based on the results obtained by this study, it was noted that the pollen grains of two plants: Foeniculum vulgare and Eryngium campestre were triaperturate, while at the pollen grains of E. maritimum and Crithmum maritimum showed three furrows and three pores. The exine sculpture of the four plants varied from granulate to rugulate at the pollen grains of Foeniculum vulgare and Eryngium campestre, reticulate to scabrate at Crithmum maritimum, and rugulate at E. maritimum. The largest dimensions for the majority of the palynological indicators were identified for Eryngium campestre pollen grains and the smallest ones were found in Crithmum maritimum pollen grains.

The palynomorphological features of four species belonging to the genus Silene (Silene italica, Silene armeria, Silene pusilla and Silene fabarioides) from different regions of Albania, were investigated and studied by light microscope. This study aims to assess and highlight the existence of significant differences in pollen size, distance between two pores, the exine sculpture and pores number found in these species. Pollen grains were usually radially symmetrical, polar, polypantoporate, spheroidal. The pores were circular contours, operculate which due to thickening of intine in this zone, come out like a cupole. The number of pores varied from 20 to 26 in Silene italica, from 16 to 20 pores in Silene fabarioides and Silene armeria, and from 12 to 16 pores in Silene pusilla. The ornamentations of exine varied from microechinate to microperforate (punctate) at Silene italica, Silene fabarioides and Silene pusilla, whereas at Silene armeria the sculpure of exine was reticulate. The biggest pollen grains were found in Silene fabarioides, whereas the smallest ones were found in Silene armeria. [ABSTRACT FROM AUTHOR]

Pollen allergy is a human disease that is rapidly growing among the Albanian population. There are many plants in Albania that cause this disease and Humulus lupulus (Cannabaceae) is one of them. In this study is presented an allergopalynologic description of pollen grains of this plant. They were taken in the Elbasan region of Albania and are studied for the first time by the local researchers. The slides were prepared using two methods: acetolysis and basic fuchsine method. The results have shown that the pollen grains of H. lupulus were triporate. Also, is done the comparison of the size of pollen grains for the specie studied with others from foreign literature that belong to different habitats. The study showed the pollen grains of H. lupulus taken in Elbasan area have similarities to the morphological features with H. lupulus' pollen according to the foreign literature, but they differ from their size. By our study, it turns out that the pollen grains of H. hupulus from Elbasan habitat have smaller sizes than those obtained from the literature. We conclude that the change in the size of pollen grains caused by environmental factors and the chosen method during processing laboratory. [ABSTRACT FROM AUTHOR]

In this article we present data for new floristic records on the flora of Shebenik- Jabllanicë National Park, which extends at north - east of Librazhdi town, in the border with Macedonia. It has a total surface 33,927.66 ha and the altitude varies from 300 m to 2264 m a. s. l. The Park is under the administration of Elbasan Regional Administration of Protected Areas (RAPAs) and is one of the largest Albanian National Parks, with great values especially of being home to a rich wild flora and fauna as well, that needs further explorations due to difficult terrains and roads. The Park is known for its diversity of vascular native flora and until now it comprises more than 1000 taxa, with a large number of endemic and sub-endemic species. During our exploration we found many taxa, which are reported here for the first time as present in the park area. Many of them have limited Europe distribution being native to Albania, Macedonia, Serbia, Bulgaria, Greece and Turkey such as: Fritillaria macedonica Bornm., Vincetoxicum speciosum Boiss. & Spruner, Crocus jablanicensis N. Randjel. & V. Randjel. and others widespread, as: Tulipa sylvestris L., etc. that increase even more the number of floristic richness of this protected area. [ABSTRACT FROM AUTHOR]
