Inpo-CHiINA, Tonkin, Massif du Tam Dao, À. Petelot 4360 (type), 
May, 1931, “liane à fleurs blanches.” Also represented by Petelot 4814 
from Pho Vi, Province of Bac Giang, May, 1933, a shrub 1.5 m. high. 
A species unrelated to any of those recorded from Indo-China, char- 
acterized by its simple leaves and racemes, the latter about equalling the 
former in length. It resembles Allophylus samarensis Merr. of the 
Philippines.
