Dear Tanay one would get really confused if we compare with older Indian Floras (Flora of British India, Flora Simlensis, etc.) The species described there as R. lasiocarpus Smith (flowers pink, leaves pinnate compound, leaflets 5-11) is now R. niveus Thunb, with var. pauciflorus (few flowers) as R. niveus var. pauciflorus (Hook.f.)Saxena. The species described in these books as R. niveus Wall ex Hook.f., the different varieties are now often treated as distinct species R. mesogaeus, R. hypagyrus, etc. Our Kashmir plant commonly known as R. fruticosus var. discolor (subsequently R. discolor) is a different species, R. ulmifolius with 3-5 leaflets (palmate), sulcate (channelled) and pruinose branches and crumpled white to light pink petals. Both R. ulmifolius and R. discolor are described in Flora Europaea.
