Taxonomic Revision Of The Family Salicaceae Of Pakistan

The present study of confined to the taxonomic revision of family salicaceae of Pakistan. In this family considerable hybridization between different taxa is involved and there is considerable morphological variation within each species. The extensive availability of frequently misidentified plant specimens. In different herbaria of Pakistan suggest that it is taxonomically a difficult family. Some species of the genus Salix Linn show nomenclatural problems. The present study was therefore under taken to clear up the taxonomic position of a number of taxa. Minute character have been considered for the delimitation of various taxa, e.g. pubescence, the length and position of the pedicle and peduncles, the length of catkin, the size and shape of leaves, the size and shape of capsule, etc.. Numerical analysis was carried out using following computer packages: SPSS &statistical cluster analysis was used and delineate and defined taxa. Result are presented in the form of keys and dendrogram
