Racemes axillary, densely flowered, the rachis more or less pilosulous or pubescent, 
6 to 9 cm. long. Peduncles and pedicels grayish-pubescent, the former usually 
biflorous, about 1 mm. long, the latter 1.5 to 2.5 mm. long; bracts and bractlets very 
small, ovate, scarious, ciliate, the bractlets opposite, inserted at the base of the calyx 
stipe. Calyx cupulate, turbinate or stipitate at the base, shallowly sinuate-dentate, 
4 to 4.5 mm. long, minutely puberulous, longitudinally dark-striped. Petals crimson 
or red, thick, obscurely spotted; standard suborbicular, callous-plicate and sub- 
auriculate at the base, emarginate at the apex with the margin more or less inflexed, 
densely silvery-pubescent above the claw and along the veins without, the claw about 
2 mm. long, the blade 9 mm. long, 10 mm. broad; wings long, nalrow, arcuate, auri- 
culate, rounded-obtuse at the apex, glabrous, the claw 2.6 mm. long, the blade 7 mm. 
long, 2 mm. broad; carinal petals strongly falcate, subauriculate, rounded at the apex, 
slightly pubescent without along the veins, the claw 3.2 mm. long, the blade about 
6.5 mm. long, 2.5 mm. broad. Staminal tube glabrous. Ovary 
linear, long-stipitate, densely and minutely cano-pubescent, about 
5.5 mm. long, 4-ovulate; style arcuate, sparsely pubescent; stigma 
capitellate. 
Legume ovate-lanceolate, attenuate and substipitate at the 
base, long-acuminate at the apex, light brown, glabrous, 6.5 cm. 
long, 2.8 cm. broad, 1-seeded, the vexillar margin about 2 mm. 
broad, the carinal margin somewhat rounded. Seed dark brown, 
reniform, 11 mm. long, 18 mm. broad.

Lonchocarpus peninsularis and L. nicoyensis are known among the natives under the 
common name of “‘chaperno,’’ a fact that seems to have brought about an almost 
hopeless confusion of the collections distributed by Mr. Tonduz. Thus the flowers of 
the latter were attributed to the former and vice versa. It seems, however, that both 
species are quite distinct and hardly need be confused. Lonchocarpus nicoyensis is 
probably always a shrub, and its leaves are fully developed before the appearance of 
the flowers. These are noted by Mr. Tonduz as being red, while those of L. peninsu- 
laris are pinkish; furthermore the petals of the former species are unusually thick, 
and the wings assume a falcate, elongate shape exceptional in the genus. Lastly, the 
fruits are quite distinct.

Derris costaricensis Donn. Smith, Bot. Gaz. 44: 110. 1907. 
A deciduous tree, the branchlets thick, the grayish bark at first densely tomentose, 
later glabrous; young shoots densely reddish brown tomentose. 
Leaves 5 or 7-foliolate, the rachis 9 to 12 cm. long, terete, at first densely reddish- 
tomentose, later grayish brown pubescent. Leaflets coriaceous, the petiolules thick, 
canaliculate, about 7 mm. long, reddish brown tomentose, the blades broadly ovate 
to obovate, shortly cuneate at the base, rounded-emarginate at the apex, 6 to 12 cm. 
long, 4 to 11 cm. broad, at first velvety, later sparsely pubescent, impressed-reticulate 
above, reticulate and grayish-tomentose beneath; costa and primary nerves reddish 
brown hairy on both faces, slightly prominent above, strongly so beneath. Stipules 
short, broad, rounded at the apex, reddish brown hairy.
