A medium-sized tree with rounded crown; branchlets pubescent or glabrous, 
angular. 
Leaves glabrous or glabrescent, the rachis marginate or narrowly winged 
below each pair of leaflets, terete and nude above them, 3.5 to 10 cm. long, the 
petiolar part 0.8 to 2 cm. long; stipules narrow-lanceolate or linear, acute, per- 
sistent, 6 to 12 mm. long; leaflets 1 to 3-jugate, sessile or almost so, coriaceous, 
bullate; glands large, sessile, salver-shaped; blades oblique, broadly ovate to 
obovate, rounded or attenuate toward the base and emarginate on the broader 
side, obtuse or subacute and often mucronate at the apex, dark green and lus- 
trous above, with the costa prominent and minutely pubescent and the veins 
deeply impressed, beneath light green, with the costa, veins, and venules 
strongly prominent, the blades of the basal pair 8 to 19 cm. long, 5 to 10 cm. 
broad, those of the terminal pair 15 to 26 cm. long, 8 to 14 cm. broad. 
Inflorescences paniculate and terminal; peduncles stout, 2.5 to 4 em. long, 
minutely brownish-pubescent ; flower heads dense, elongate, the rachis minutely 
pubescent, 3 to 4 em. long; flowers sessile; bractlets ovate-lanceolate, pubescent 
without and within, shorter or longer than the calyx; calyx broad, irregularly 
cleft.at the tip, minutely pubescent outside and inside, 7 to 8 mm. long; corolla 
tubular, broadening toward the tip, silky-villous, 18 mm. long, the lobes narrow, 
about 5 mm. long; staminal tube included ; style subcapitellate. 
Legume glabrous, 80 to 60 cm. long, about 7 cm. broad, and 2.5 to 8 em. thick, 
the margins rounded and smooth, the apex obtuse; seeds 7 to 16 or more, 
immersed in an insipid white pulp. 
The type material was from Santa Marta, Colombia.

This tree is sometimes cultivated on account of the edible pulp contained in 
its enormous pods, but there is no doubt as to its being indigenous in Panama 
and Costa Rica. <A leaf collected in the vicinity of Sepacuité, Alta Verapaz, 
Guatemala, by Cook and Griggs may also belong to this species. 
Bentham’s statement that the corolla is “ subpollicaris”—almost an inch 
long—does not hold with our specimens, in which that part of the flower is 
only 18 mm., that is to say, 84 lines long. The other discrepancies have already 
been mentioned by Seemann in the Voyage of the Herald.

A small tree; branchlets terete, slender, the younger parts sparsely light 
brown hairy. 
Rachis of the leaves also light brown hairy, very narrowly winged, 4 to 8 cm. 
long, the petiolar part 3.5 to 6 cm. long; stipules ovate, acute, 6 to 9 mm. long, 
4 mm. broad, pubescent, persistent; leaflets 1 to 3-jugate, petiolulate, mem- 
branous or subcoriaceous; glands very small, sessile; petiolules 4 mm. long,
