Abstract
Floristic composition of grasses in Cholistan desert has been lacking. Therefore, this study aims at s to provide the identification, life form, life trend and abundance of grass species in Cholistan desert. For the said purpose, floristic survey was carried out for a period of two years. Twenty seven grass species belonged to16 genera were identified. Floristic analysis reflects that the genus Eragrostis as being the most representative with 05 species (18.5%) followed in descending order by Aristida and Cenchrus with 04 species (14.8%) each and Panicum with 02 species (7.4 %) while the remaining genera have one species each. Therophyte was the most abundant life form consisted of 16 grass species (59.2%) followed by hemicryptophytes 09 species (33.3%) and phanerophytes 02 species (7.4%). Overall summary of grass species showed that, 06 species (22%) were very common, 14 species (52 %) were common and only 07 species (26%) were found rare. Overall 13 annuals grass species (48 %) and 14 perennials grass species (52%) were recorded. This floristic information will provide a useful starting point for further ecological and bio-prospective researches in this hot desert area.
