PITTIER—MIDDLE AMERICAN SPECIES OF LONCHOCARPUS. 63 
carinal side, almost glabrous, the claw 4.5 to 5 mm. long, the blade 10 mm. long, 5 
to 5.5 mm. broad; carinal petals falcate, rounded-auriculate at the base, obtuse at 
the apex, the claw 4.5 mm. long, the blade folded near the base, sparsely silky- 
pubescent without and within, 10 mm. long, 4.5 to 5 mm. broad. Vexillar stamen 
freeat the base. Ovarysessile, linear, 3.5 mm. long, 8-ovulate, silky-pubescent; style 
arcuate, pilosulous, exceeding the stamens, the stigma capitellate. 
Legume coriaceous, ovate-lanceolate, compressed, attenuate-stipitate at the base, 
rounded-mucronate at the apex, glabrous, 1 or 2-seeded, 8 to 8.5 cm. long, 3 cm. broad, 
both margins thin-edged. 
Type in the herbarium of the Field Museum of Natural History, collected at 
Xbalché, Yucataén, Mexico, by Dr. G. F. Gaumer (no. 904).

Closely related perhaps to L. punctatus H. B. K., but differing in the number, 
shape, and dimensions of the leaflets, the ciliate, glandular calyx, and the size and 
shape of the petals and legume. 
12. Lonchocarpus chiricanus Pittier, sp. nov. PuaTE 3, A. 
A small deciduous tree, the branchlets grayish, glabrous, lenticellate. 
Leaves 7 or 9-foliolate, the rachis subterete, canaliculate, glabrous, thicker at the 
insertion, 10 to 12 cm. long. Leaflets coriaceous, densely pellucid-puncticulate, the 
petiolules canaliculate, thick, 6 to7 mm. long, the blades ovate or obovate, rounded 
at the base, subacuminate and obtuse at the apex, 6.5 to 11 cm. long, 4.5 to 6 cm. 
broad, dark green and sublustrous above, paler (almost glaucous) and minutely 
pilosulous beneath, the costa and veins glabrous and prominent. Stipules not known. 
Flowers not known. 
Legume flattened, club-shaped, ovate, long-stipitate at the base, abruptly acumi- 
nate at the apex, glabrous, subligneous with a suberous mesocarp, 1-seeded, about 
10 cm. long and 4 cm. broad, both margins thin-edged and sharp. Seed reniform, 
rich brown with a whitish hilum, about 2.3 cm. long, 1.5 cm. broad, and 6 mm. thick. 
Type in the U. S. National Herbarium, no. 677284, collected on Parida Island, 
Province of Chiriqui, Panama, in fruit, February 25, 1911, by H. Pittier (no. 2817). 
The transparent-dotted leaflets indicate that the place of this species is in the sec- 
tion Punctati; the characters of the legume and seed show that it is distinct from L. 
benthamianus and L. proteranthus; the presence of the minute pubescence on the 
lower face of the leaves, presumably the remnants of a denser initial indument, 
almost excludes the possibility of the specimens belonging to L. punctatus or L. lon- 
gipedicellatus, etc. Notwithstanding the absence of the flowers, it seems permissible 
to consider this tree a distinct species. 
13. Lonchocarpus proteranthus Pittier, sp. nov. PLATE 3, B. Fiaure 11, 
A tree 15 to 20 meters high, the trunk 35 to 40 cm. in diameter at the base, the 
branchlets sparsely lenticellate, the young growth glabrous or puberulous. 
Leaves mostly 9-foliolate, glabrous, the rachis 10 to 14 cm. long, subterete, thickened 
at the base. Leaflets petiolulate, coriaceous, pellucid-punctate, the petiolules 7 mm. 
long, narrowly canaliculate, dark greenish brown, the blades ovate-oblong, broadly 
rounded at the base, shortly and obtusely acuminate at the apex, 3.5 to 9 cm. long, 
2.3 to 3.8 cm. broad, the venation finely reticulate and prominent on both faces. 
Stipules not seen.
