Abstract
Many grasses are being used as sourece of traditional medicines in many areas of world. Howver, it is very hectic to identify grasses properly. The present research work was conducted to determine taxonomic status of some selected grass species being used in medicinal purpose in District Bhimber of Azad Jammu and Kashmir (AJK). Following species grasses: Cynodon dactylon L., Saccharum spontanium L., Saccharum ravennae L., Poa annua L. and Poa nemoralis L. were selected for study from district Bhimber (AJK). In taxonomical study morphometric analysis and leaf epidermal anatomy approaches were employed, furhtrer stomatal index parameters were also studied. In morphometric study; cluster was formed which divided relevant species into their group (taxon) genus. Genetic distances were also calculated for their inter and intra-species variation analysis. Genetic distance among the species of Bhimber was 135 GD, among species of Barnala was 83 GD and among species of 108 GD. During the leaf epidermal study of grasses stomatal index was calculated highest stomatal index was found Saccharum spontanium (23.6), after that Poa nemoralis stomatal index is (20.4). Cynodon dactylon showed stomatal index of (15), Saccharum revennae (12.6) and the lowest stomatal index of upper epidermis was found in Poa annua (12.5). Economic potential of the species was calculated and tabulated along with their medicinal potential. Economically Saccharum spontanium was more potent than other species having highest value of economic potential.
