XIV. 4 Merrill: Noteworthy Philippine Plants, XV 405 



This species is allied to Rourea erecta (Blanco) Merr., from 

 which it is especially distinguished by its fewer, differently 

 shaped, not slenderly acuminate leaflets; and its smaller, nearly 

 equilateral, slenderly pedicelled fruits which are racemosely 

 arranged.

TRIFIDACANTHUS Merrill 



TRIFIDACANTHUS UNIFOLIOLATUS Merr, in Philip. Journ. Sci. 12 

 (1917) Bot. 269. 



Pods straight, about 2 cm long, usually composed of three or 

 four 1-seeded joints, flat, thin, reticulate, sparingly pubescent, 

 the upper suture nearly straight, slightly indented between the 

 joints, the lower suture rather deeply indented ; joints usually 6 

 to 7 mm long, about 4 mm wide, the valves chartaceous or thinly 

 coriaceous. 



Luzon, Ilocos Norte Province, Burgos, Bur. Sci. 32925 Ramos, 

 July 18, 1918, in dry thickets at low altitudes. 



The original description of this new genus and species was 

 based on flowering specimens, but the second collection, and this 

 from the type locality, shows that I was correct in placing it in 

 the Papilionatae-Hedysareae-Desmodiinae, the Desmodiinae 

 being indicated in the original description with doubt. It is 

 manifestly most closely allied to Desmodium, from which, among 

 other characters, it is distinguished by its characteristic spines.
