Paul Ormerod ( 1995 ) in Orchadian 11 ( 7 ) : 325. The new combination of this species is Rhomboda moulmeinensis ( Par.et Rchb.f. ) Ormd.We disagree with his opinion after study and think it is better to put it in this genus.
He is reported from Sinc-British Plant Expedition no 0197 in Fanjing Mountain, Guizhou Province, China.This specimen is described as a new species of Rhomboda fanjingensis Ormd. Because this species is widely distributed in southern and southwestern China, its leaf shape, size, perianth shape, internal structure and shape also have certain changes due to different habitats. |
