Abstract


We demonstrate that Ranunculus angustisepalus (Ranunculaceae) described from Bomi in southeastern Xizang (Tibet) is conspecific with Oxygraphis delavayi, a species widely distributed in northern Sichuan, southeastern Xizang, and northwestern Yunnan, China. We therefore place the former in synonymy within the latter. We also reduce Ranumculus subgen. Stenoglossa and R. sect. Stenoglossa, both with R. angustisepalus as their type, to the synonymy of the genus Oxygraphis.
