Indo-China, Tonkin, Xoan Dao, Pho Ba Che, Pélelol 4029 (type). 



A species characterized by its small leaves, the basai glands normally 

 absent, but if présent, then a single one clearly évident on the lower surface 

 and slightly concave but not at ail saccate, and its unusually short inflo- 

 rescences and small flowers. While I hâve tentatively placed it in the section 

 Cylopygeum I am by no means convinced that it belongs hère, but in the 

 absence of fruits nothing further can be done with it at présent. With the 

 description of thèse two new species the total number of Indo-China species 

 is now five.
