DATA ON THE PALYNOMORPHOLOGICAL CHARACTERISTICS OF FIVE PLANTS OF COMPOSITAE FAMILY IN THE REGION OF ELBASAN, ALBANIA

Palynomorphological characteristics of the five plants of Compositae Family: Arctium lappa, Solidago virgaurea, Cichorium intybus, Senecio vulgaris and Leontopodium alpinum (the latter is very rare plant (status R) according to the data of IUCN), pollens of which were collected in fresh condition to the habitat of Great Site of the mountain Polis, were provided for the first time in the Albania’s palynological literature by this article.This article aims to assess and highlight the existence of differences of some morphological features of the pollen grains of this family, regardless common particulars which distinguish the pollens of Compositae plants such as: the aperture three furrows three pores and the echinate exine. Regular pollen grains of three plants: Senecio, Leontopodium and Solidago were 3-zonocolporate, oblate spheroidal to prolate spheroidal and could be classified as Senecio type based to the data of the palynological literature. Three sharp tip furrows with smooth membrane and three pores with circular frames which due to thickening of intine in this zone, come out like cupoles, were identified to the pollen grains of the plants of genus: Senecio, Solidago and Leontopodium. Based on the results obtained by this study, it was concluded that the exine sculpture of the pollen grains of the five plants was echinate which vary from fenestrate-perforate at Cichorium, to echinate accompained by small verruca at the pollen grains of Arctium, echinate accompained by small granules at the pollen grains of Senecio, echinate accompained by hools in the base of every spine at the pollen grains of Solidago, and echinate accompained by microspinules at Leontopodium alpinum.
