Shrub or small tree, the branchlets puberulent. Leaves several- to many- foliolate, up to 3.5 cm. long; petiole about 3 cm. long, puberulent, eglandular; rachis similar to petiole; stipules ovate-rotund, acuminate, up to 12 mm. long; leaflets normally 8-16 pairs, oblong or elliptic, up to 5 cm. long and almost 2 cm. wide, basally inequilaterally obtuse, apically obtuse or acute and mucronate, sub- sessile, lightly pubescent, the hairs from a pustuliform base in dried material. In- florescence of a few subterminal racemes up to 3 dm. long, the buds approximate and ensheathed by ovate bracts about 12 mm. long. Flower yellow; sepals elliptic, imbricate, sessile, about 15 mm. long; petals obovate to elliptic, up to 2 cm. long, markedly venose, short-clawed; stamens 4-morphic; anther of lowermost center stamen about 7 mm. long, with terminal pores and lateral slits, prominently hastate basally, this anther bounded on either side by a stamen with a large anther about 12 mm. long, similarly dehiscent, sagittate basally, arcuate; anthers of 4 median stamens subequal, about 5 mm. long, long-rostrate, sagittate, dehiscent as the lowermost; uppermost 2-3 stamens rudimentary, distorted; ovary tomentose.

Note

If the Johansen specimen typifies the species, it is very little different from C. nicaraguensis. It differs chiefly in pubescence characters and in having smaller, different-shaped stipules. The plant is reported to emit an unpleasant odor when bruised.
