17,3 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 leaflets; 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. 3^675 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.
