-Inpo-CHINA, southern Annam, near Dalat, R. W. Squires 823, April 
12, 1932, in open rocky forests, only a few plants seen. 
This is apparently most closely allied to Munronia sinica Harms from 
Which it differs notably in its vegetative characters and in its much 
shorter flowers. It is not closely allied to the two species hitherto 
recorded from Indo-China, Munronia pauciflora Harms and M. Robin- 
sonii Pellegr. More often the lower leaves are 3-foliolate and rather 
Prominently toothed, while the upper ones usually have 5 leaflets which 
are normally entire and often larger than those on the lower leaves; 
again the terminal leaflet is always larger than the lateral ones.
