Trees to 55 m tall; trunk buttressed to 3 m; young branches sparsely puberu- lous-glabrescent. Leaves trifoliolate; petioles 2.5-11 cm long, glabrescent, terete; leaflets shortly petiolulate, the terminal petiolule 4-7 mm long, the lateral pet- iolules slightly shorter than the terminal one, the petiolules sparsely puberulous, shallowly canaliculate; blades elliptic to oblong, slightly asymmetrical, apically acuminate, the acumen 1-1.5 cm long, basally cuneate to subcuneate and often markedly unequal, the margins unevenly coarsely serrate, glabrous on both sur- faces, the terminal leaflet 7.5-12 cm long, 2.5-5.5 cm broad, the lateral blades slightly smaller than the terminal one, the primary veins 10-11 pairs, plane to prominulous beneath, the venation prominulous beneath; stipels to 5 mm long, ellipsoid, inflated, persistent. Inflorescences clustered racemes; peduncles 3.5-7 cm long, glabrous; rachis tomentose; pedicels elongate, ebracteolate. Flowers with the calyx cupuliform, ca. 6 mm long, glabrous on the exterior, the lobes 5, small, rounded, the margins ciliate; corolla lobes 5, ca. 2-2.5 cm long, oblong, glabrous, greenish yellow; stamens numerous, ca. 200, the filaments basally shortly united in a ring, but into groups, white, sparsely pubescent, the apical portion tuberculate, the innermost filaments much shorter than the rest, the anthers small; ovary globose, glabrous on the exterior, 4-locular; the styles 4, filamentous, shorter than the filaments. Fruits globose-ellipsoid, ca. 5.5 cm long, the exocarp glabrous, smooth, the pericarp thick, fleshy, the mesocarp and endocarp enveloping the seed to form an ovoid stone, the exterior of the mesocarp not seen, the interior enveloping the endocarp tubercles, the endocarp with numerous flattened tuber- cles ca. 5 mm long, and a hard woody interior ca. 1 mm thick, glabrous within. This species is also common in the Magdalena valley region of Colombia. It is most closely related to C. costaricense from which it differs in the absence of a hirsute mass at the junction of the primary veins and petioles, the smaller leaves with a more coarsely serrate margin, and the more inflated stipels.
