Palyno-anatomical characters and their systematic significance in the family Apiaceae from Chitral, eastern Hindu Kush, Pakistan.

The present study was performed to provide a detailed explanation of leaf epidermal anatomy and pollen micromorphological features of selected species of family Apiaceae from Chitral, eastern Hindu Kush region as the basis of forthcoming studies. In the present article pollen morphology of eight species and foliar epidermal of seven species of family Apiaceae have been examined through microscopic techniques. In results two types of pollen prolate (five species) and perprolate (three species) with three colpi have been recorded.

Taxonomic implications of macro and micromorphological characters in the genus Brachythecium (Brachytheciaceae, Bryopsida) from the Western Himalayas: A combined light and scanning electron microscopic analysis.

Brachythecium Schimp. is one of the most complex and diverse genus among the pleurocarpous mosses, having almost 150 species distributed around the world. The current study presents a detailed morphological analysis of the six species of the genus Brachythecium in Western Himalayas, Pakistan.
