Inpo-CxiNA, Sontoy Province, To Phap, Pételot 2600 (Tyrz, fruit), 2610, 2643, 
June 2, July 7, and August 15, 1940, a large tree near water courses. 
This species clearly belongs in the group with Vatica astrotricha Hance, 
V. faginea Dyer, and V. Dyeri King, differing from all of them in its indu- 
mentum, which occurs only on the very youngest branchlets, the vounger 
parts of the inflorescences, and on the flowers; this indumentum is minute 
and consists of more or less scattered, very short, cinereous or, at times, sub- 
ferrugineous stellate hairs of a type quite different from that of the three 
species listed above. Vatica tonkinensis A. Chev. Bull. Écon. Indo-Chine 
20: 799. 1918, remains undescribed, like the considerable number of other 
proposed new species in various families whose names appear in the same 
paper.
