20 cm long, 3.5 em wide, smooth, shining, irregularly sinuate and de-

incurved beak, the stipe slender, about 4 cm long. Seeds 6 or 7 in each 
pod, flattened, black, elliptic in outline, about 2 cm long. 
Luzon, Province of Benguet, Twin Peaks, Elmer 6439, June 8, 1904. 
A species in vegetative characters similar to Pithecolobium scutiferum, but 
distinguishable at once by its very different pods.

Arbor parva, subglabra; foliis bipinnatis, pinnis 2-jugatis, foliolis 2- 
vel 3-jugatis, elliptico-ovatis vel oblongo-ovatis, chartaceis vel submem-

obtuse acuminatis, interdum caudato-acuminatis, nervis utrinque 3 vel 
4, prominentibus, valde obliquis; floribus sessilibus, capitato-dispositis ; 
leguminibus circinatis, 10 ad 12 em longis, circiter 1.5 em latis, in sicco 
extus nigris vel brunneis, intus rubris. 
A small tree (4 m high fide Clemens), glabrous or nearly so, or the 
branchlets and inflorescence at first slightly pubescent. Branches terete, 
light-gray or brown, somewhat lenticellate. Leaves bipinnate, the petiole 
and rachis varying from 5 to 10 cm in length, with from two to four 
small sessile glands on the upper surface; pinnae 2-jugate; leaflets 2- or 
3-jugate, those on the upper pair of pinnae usually 3-jugate, those on 
the lower pair 2-, rarely 1-jugate, elliptic-ovate to oblong-ovate, char- 
taceous or submembranaceous, slightly shining when dry, 7 to 12 cm 
long, 3 to 5 em wide, the base acute, the apex usually rather abruptly acu- 
minate, the acumen blunt, or sometimes the apex caudate-acuminate ; 
nerves prominent, curved-ascending, 3 or 4 on each side of the midrib, 
the reticulations lax; petiolules about 2 mm long. Panicle-branches 
very slender, elongated, the flowers sessile, in heads of from three to five 
flowers each at the ends of the branchlets, the bracts and bracteoles 
small, about 1.5 mm long, obtuse, oblong. Calyx about 1.5 mm long, 
glabrous, with five broad teeth. Corolla 5 mm long, the lobes somewhat 
acuminate, veined. Stamens about 50, nearly 1.5 em long. Pods 10 to 
12 em in length, about 1.5.cm wide, curved into an almost complete 
circle, glabrous, ultimately dehiscing by both sutures, before dehiscence 
not sinuate between the seeds, the base acute, the apex rounded, when
