Abstract
The present work was carried out to evaluate the floristic checklist and environmental distinctiveness of Plants of Parachinar, Kurram Agency across the year during 2014- 2015. A total of 283 species of 222 genera among 85 families were recorded. Asteraceae with (29 Sp.) was the most dominant followed by, Poaceae with (20 Sp.), Papilionaceae, Lamiaceae each with (19 Sp.), Brassicaceae (16 Sp.), Solanaceae (13 Sp.), Rosaceae (9 Sp.) and Polygonaceae (7 Sp.). While Euphorbiaceae, Caryophylaceae and Pinaceaeeach with (6 Sp.) were the co-dominant taxa. Rest of the families possessed either 5 or fewer species. Based on the habitat 252 (89.04%) species were grew in dry places as wild mesophytes and xerophytes. Seventeen species (6.00%) were cultivated while 11 species (3.88%) were aquatic. There were 18 spiny species (6.36%). Among the perennial, majority were evergreen. Three species (1.06%) namely Cuscutareflexa, Periplocaaphylla and P. calophyllawere leafless. The leaf lamina was simple in 230 species (81.27%) and 50 species (17.66%) contained composite foliage. Therophytes107 (37.80%) and nanophanerophyte 47 species (16.66%) respectively were dominant life form groups. Leaf spectra revealed that nanophylls with 121 species (42.75%) and leptophylls with 89 (31.44%) were dominant leaf size classes. The vegetation was also characterized by microphylls and mesophylls but of least concern. Key word: Ecological characteristics, Kurram agency, Floristic composition, Biological spectrum, Pakistan.
