Indo-China, Tonkin. Sontoy Province, Mount Bavi, Pételol 6608, in open humid 

 forests. 



This is clearly distinct from any of the five species admitted by Lecomte 

 as occurring in Indo-China. It is characterized by its relatively thin leaves 

 which are glaucous beneath, its short substellate-subfurfuraceous indu- 

 mentum on the inflorescences and younger parts, and by its few-flowered, 

 simple staminate umbels. In accordance with Warburg's arrangement of 

 the species it apparently belongs in the grou[) with Knema Pierrei Warb. 

 which has much larger, more numerously nerved leaves.
