Here we have a S.W. Chinese representative of the type found 
further East and North in the Tali Rh. brachyanthum, Franch. 
and in Rh. hypolepidotum, Balf’ f. et Forrest of the Mekong- 
Salween divide. It recalls also in many ways Rh. charitopes, 
Balf. i. et Forrest from N.E. Upper Burma. With these it forms 
a special phylum in the Series of Campylogynum. Its distincitve 
features are to be found in the leaves densely lepidote above and 
discontiguously black-punctulate on the grey-white surface below, 
the green sepals with prominent fan-shaped venation, the green- 
yellow corolla and the thin lepid®te style.
