Abstract
In this study, Scorzonera L. (Asteraceae) collected from Pakistan was investigated by its morphology, leaf epidermal anatomy and pollen grain characteristics. Scorzonera is a perennial herb growing in wet nutrient-poor grasslands and wet heathlands. The stem texture is glabrous in Scorzonera ammophila, Scorzonera picridioides and Scorzonera virgata while tomentose in Scorzonera hondae and terete with fine striate above in Scorzonera laciniata. The bifacial leaves had anomotetracytic, amphianisocytic, brachyparacytic and staurocytic stomata. The pollen morphology results indicate that pollen grains in Scorzonera were lophate. Based on sculpturing, all pollens were echinate in Scorzonera. The pollen class was trizonocolporate in all taxa.
Key words: Morphology, palynology, anatomy, Scorzonera L., scanning electron micrographs, Pakistan.
