Ixpo-Cxin4, Tonkin, Sontoy Province, Mount Bavi, Pételot 6607, Nov. 1, 1940, in 
open humid forests, altitude about 150 m. 
À species characterized by its fairly ample, acuminate, slenderly but 
distinctly nerved, rather thin leaves, and especially by its fascicled promi- 
nently rostrate fruits which are borne in the axils of fallen leaves on the 
older leafless branches. It is not closely allied to any of the species placed 
in the series Ramiflorae by myself and Miss F reeman, in our treatment of 
the known species of the genus, Proc. Am. Acad. Sci. Arts 73: 27 1-310. 
1940 (Mem. Gray Herb. 5: 271-310).
