Microscopic investigations of some selected species of Papilionaceae through SEM and LM from Skardu valley, northern Pakistan

Pollen morphology of 10 species and foliar epidermal anatomy of eight species of Papilionaceae from Skardu valley, northern Pakistan has been estimated for the first time. The present study was commenced with an aim to provide a detailed account of the pollen morphology by scanning electron microscopy and foliar epidermal anatomy by light microscopy. The pollen aperture was tricolporate with reticulate exine in the selected species. Stomata types are actinocytic, paracytic, and anomocytic. Irregular or polygonal with undulate or straight walls, epidermal cells were reported. A unique diversity was observed in the foliar trichomes that show the taxonomic significance of the discrimination of taxa. Non‐glandular trichomes were observed in the selected species which are unicellular with thin, long and pointed apical cells. Pollen and foliar micro morphological characters proved to be helpful for the identification of taxa at a specific level.
