Oxytropis mandokhailii N. Khan, A. Sultan et M. Rashid sp. nov.
Diagnosis: The new species has affinities to Oxytropis margacea by its narrow leaflets, basally connate stipules and inflorescence longer than leaves, but differs by its heteromorphic, longer leaves. Oxytropis margacea has 3-5 cm long leaves while O. mandokhailii has 6-14 cm long leaves. The new species also has longer stems (20-110cm) while O. margacea has 15-20 cm long stems. Calyxin O. mandokhailii is black and white appressed pubescent, while calyx has white minute appressed hairs in O. margacea. The new species also has affinities to Oxytropis cabulica by its peduncle longer than leaves andcalyx with black and white appressed hairs, but differs by its connate stipules opposed to free stipules in O. cabulica, linear to lanceolate leaflets, longer stem up to110 cm long, versus oblong to elliptic leaflets and stem upto 30 cm long in O. cabulica. The new species also differs by its stipitate, unilocular, black and white pubescent legume opposed to subsessile partially bilocular, black pubescent legume in O. cabulica.
