PITTIER—-MIDDLE AMERICAN SPECIES OF LONCHOCARPUS. 67 
Racemes few, axillary or terminal, subsessile, the rachis ferruginous-pubescent, 
4cm. long or longer. Peduncles and pedicels ferruginous-hairy, the former biflorous, 
not over 1.5 mm. long, the latter 2 to 3 mm. long; bracts and bractlets very small, 
ovate, hairy, the latter opposite, inserted near the upper end of the pedicels. Calyx 
cupulate, truncate or slightly 5-toothed, 2.5 to 3 mm. long, minutely ferruginous- 
pubescent without, reddish-lineolate. Petals pink, marked with darker lines fol- 
lowing the veins; standard suborbicular, flat, 2-lobulate and callous-plicate at the 
base, emarginate at the apex, sparsely silky-pubescent with- 
out, the claw 1.5 mm. long, the blade about 9.5 mm. long, 
11 to 11.5 mm. broad; wings oblong, auriculate, broadly ob- 
tuse, sparsely pilosulous without, the claw about 3 mm. long, 
the blade 8.5 mm. long, 3.5 mm. broad; carinal petals ob- 
lique, obovate, subfalcate, calcarate at the base of the blade, 
broadly obtuse, sparsely hairy without and ciliate at the apex, 
the claw as in the wings, the blade 6.5 to 7 mm. long, 3 to 
3.5 mm. broad. Staminal tube glabrous. Ovary linear, 
grayish-pubescent, about 7 mm. long, 8-ovulate; style gla- 
brous, arcuate; stigma conspicuously bilobulate.

Near Lonchocarpus oaxacensis, with which it has in common the relatively long, 
7 or 8-ovulate ovary and the pubescent leaflets, but from which it differs in the smaller 
number of the leaflets, in the pink, lineolate petals, and in the peculiar conformation 
of the base of the blade in the carinal petals.

A small tree, the branchlets reddish brown, glabrous. 
Leaves unifoliolate, glabrous; petiolules slender, subcanaliculate, thicker and 
dark-colored at base and apex, 1.3 to 3.5 cm. long; leaflets ovate, rounded at the base, 
with a long and narrow obtuse acumen at the apex, 10 to 12.5 
em. long, 3.5 to 7 cm. broad, coriaceous, dark green above, paler 
and reticulate beneath, the costa and veins prominent. Stip- 
ules not seen. 
Racemes axillary, the rachis sparsely pilosulous, 12 to 15 cm. 
long. Peduncles and pedicels grayish-pubescent, the former 1 
to 2 mm. long, usually geminate and biflorous, the latter 2 to 
2.5 mm. long; bracts and bractlets ovate-oblong, grayish- 
pilosulous, the latter in a pair close to the calyx. Calyx cupu- 
late, grayish-pubescent without, broad, about 2 mm. long, dis- 
tinctly denticulate, the carinal tooth more prominent. Petals
