Abstract:Ophiorrhiza gracilis Kurz was reported from China by several authors previously. Relevant specimen examination and field investigations revealed that it is actually a misidentification of O. caudipetala, which is known to be only distributed in India. Thus, its new record for the flora of China is reported here. Ophiorrhiza caudipetala can be distinguished from other species of the genus in China by its leaves usually in distinctly unequal pairs and corolla lobes with 0.6-1 mm long dorsal horns.
