17,8 Merrill: Noteworthy Philippine Plants, XVI 263 
A small tree, about 4 m high, the inflorescences prominently 
ferruginous-pubescent on the younger parts, the plant otherwise 
nearly glabrous, the branchlets dark brown when dry, prom- 
inently angled. Leaves about 40 cm long, the pinnae usually 
about 10 pairs, the lowest 1 or 2 pairs usually much shorter 
than the others, the intermediate ones up to 17 cm long, the main 
rachis slightly pubescent as are the secondary ones, angular, 
and with a single prominent gland near the base, the secondary 
rachises with a single small gland at the base of the ultimate 
pair of leafiets; leaflets on the intermediate pinnae about 15 
pairs, rhomboid or obliquely rhomboid, very inequilateral, the 
midrib diagonal, subcoriaceous, brown and strongly shining 
when dry, 1.5 to 3.5 cm long, 6 to 15 mm wide, acuminate, the 
lower surface very sparingly pubescent. Panicles terminal, 
ample, peduncled, up to 50 cm long, the flowers white, numerous, 
subumbellately crowded at the tips of the ultimate branchlets, 
sessile or nearly so, the subtending bracteoles obovate to oblong- 
obovate, somewhat acuminate, about 3 m long. Calyx about 
4 mm long, densely ferruginous-pubescent, cup-shaped, the teeth 
triangular, acute, about 1 mm long. Corolla 8 to 9 mm long, 
densely ferruginous-pubescent, the lobes oblong-ovate, about 3.5 
mm long. Ovary oblong-ovate to somewhat obovate, pubescent, 
1.5 to 2 mm in length. 
MINDANAO, Surigao Province, Bur, Sci. 34675 Ramos & Pas- 
casio, June 15, 1919, along streams at low altitudes at the iron 
deposit on the northeast coast. 
A species belonging in the group with Pithecolobium clypearia 
Benth. and in this group apparently most closely allied to 
Pithecolobium contortum Mart., from which it is readily 
distinguished, among other characters, by its very densely 
ferruginous-pubescent corollas.
