چکیده

In the present study, we shortlisted 71 endemic and subendemic plant species in three diverse families, orobanchaceae, plantaginaceae, and scrophulariaceae from the political territory of pakistan. among them, orobanchaceae has the highest number of species (47 spp., 66.20%), including four genera: pedicularis and euphrasia, each with (21 spp., 44.68%), followed by orobanche with (4 spp., 8.51%), and christisonia, which has one species (2.13%). plantaginaceae contains (14 spp., 19.72%), including four genera: lagotis, linaria, and veronica, each with (3 spp., 21.42%), followed by plantago with (2 spp., 14.28%), and campylanthus, chaenorhinum, and picrorhiza, each having a single species (7.14%). scrophulariaceae includes only the genus scrophularia with (10 spp., 14.08%). some species-rich genera (e.g., euphrasia, pedicularis, and scrophularia) are extensively distributed in the himalayan region, which is regarded as a significant hotspot and a center of speciation for these genera. it is concluded that the species richness and proportion of these endemic plants are highly diversified in northern pakistan due to altitudinal gradients, which show a response to altitude.
