Indo-Chin.a: Tonkin, Chapa, Pételot 2185, 2194 (type), September 

 1929 and .'^ugust 1932, in open forests, altitude 1500 to 1800 m., flowers 

 yellow. Type deposited in the Gray Herbarium. 



A species clearly allied to Thladiantha villosula Cogn. of Hupeh and 

 Yunnan, differing in its longer, many flowered, staminate racemes, larger 

 flowers, the strikingly and densely granulose-glandular margins of the 

 petals, and in its indumentum. The weak, rather pale, mostly spreading, 

 distinctly jointed trichomes on the younger végétative parts and in- 

 florescences are very conspicuous and characteristic.
