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.

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.
