species, but is at once distinguished by its aculeate branches, 

 petioles, and leaves, as well as by its rather larger paniculate 

 inflorescences. The most striking character of the present spe- 

 cies is found, however, in the sepals which are remarkably 

 dissimilar, two being narrowly lanceolate and entire, the other 

 three being obovate and deeply laciniate.

 ad elliptico-lanceolatis, acute acuminatis, 8 mm longis, petalis

A tree about 5 m high, the young parts somewhat appressed- 

 pubescent. Branches about 2 mm in diameter, brown, terete, 

 slightly pubescent, ultimately glabrous. Leaves 7 to 10 cm 

 long, the rachis slightly pubescent and with a single conspicuous 

 gland halfway between the lower pair of leaflets and the base 

 of the petiole; leaflets 20 to 28, subcoriaceous, inequilateral, 

 sessile, subolivaceous, ultimately glabrous, the apex obtuse 

 and minutely apiculate, the base rounded, the midrib situated 

 in about the upper one-third of the leaf, the lateral nerves 

 ascending, slender, about 6 on each side of the midrib ; stipules 

 linear-lanceolate, acuminate, 3 mm long. Flowers yellow, about 

 2 cm in diameter, in few-flowered, supra-axillary fascicles or 

 the lower inflorescences racemose, the rachis produced about 

 5 mm, the inflorescences usually in pairs; bracts about 2 mm 

 long, abruptly linear-lanceolate, and acuminate from a broad 

 base ; bracteoles 2, near the apex of the pedicels, linear-lanceolate, 

 acuminate, 2 to 2.5 mm long. Sepals lanceolate to elliptic- 

 lanceolate, sparingly appressed-pubescent, acutely acuminate, 

 about 8 mm long. Petals obovate, 10 mm long, 7 to 8 mm wide, 

 rounded, base cuneate, glabrous. Anthers 4 to 5 mm long, 

 their filaments 1 mm long or less. Ovary and style about 10 

 mm long, the former appressed-pubescent, about 5-ovulate. Pods 

 thin, narrowly oblong, oblique at both base and apex, slightly
