pedicellis 4 ad 5 mm longis; fructibus oblongis, glabris, auran- 

 tiacis, in siccitate atris, 1 cm longis, obtusis, seminibus paucis. 



Ng Chi Leng and Sha Po Leng, McClure 9326 (type), 8160, 

 November 11, 1921, and April 28, 1922, on forested slopes and 

 in damp ravines, altitude at and above 450 meters. 



A species most closely allied to Casearia philippinensis Merr., 

 from which, among other characters, it is distinguished by its 

 differently shaped, fewer-nerved, denticulate leaves.

 squamulis crassis, ciliatis, irregulariter 4- ad 6-dentatis, quam

Shui Mun, McClure 9636, May 15, 1922, on rocky stream banks. 



This species is most closely allied to Taraktogenos serrata 

 Pierre of Indo-China, from which it differs in its glabrous, not 

 ferruginous-pubescent sepals, although in the present species the 

 very young buds are sparingly pubescent. The genus is new 

 to China.
