PITTIER—MIDDLE AMERICAN SPECIES OF LONCHOCARPUS. 77 
This species is characterized by its small leaves, not unlike those of Lonchocarpus 
atropurpureus Benth. or other members of the same section, its peculiar pubescence, 
its large flowers with the style of L. mexicanus, etc. Unfortunately the petals have 
been destroyed by insects and the fruits are wanting.

A large tree with rounded crown; bark of the branchlets dark brown, pubescent, 
lenticellose. 
Leaves 7 to 13-foliolate, the rachis 12 to 17 cm. long, more or less ferruginous-pubes- 
cent, deeply sulcate. Leaflets coriaceous; petiolules 5 mm. long, subsulcate, hairy; 
leaflet blades elliptic-ovate or obovate, slightly oblique, rounded at the base, shortly 
obtuse-acuminate at the apex, 6 to 11 cm. long, 2 to 6 cm. broad, glabrous, dark green 
and Justrous above, paler and sparsely hairy on the costa and nerves beneath, the 
nerves impressed above and prominent beneath. Stipules not seen. 
Racemes axillary or paniculate at the ends of the branchlets, the rachis 20 to 24 
cm. long (as long as or longer than the leaves), slightly ferruginous-pubescent, the 
peduncular part 5.5 cm. long. Flowers 12 to 14 mm. long 
(without the pedicels), solitary or 2 or 3 together in distant 
clusters, the peduncles and pedicels ferruginous-pubescent, 
the former 1.5 to 2 mm. long, 2-flowered, the latter about 
1 mm. Jong; bracts and bractlets ovate or orbicular, the 
former about 1 mm. long, ferruginous-pubescent, the latter 
opposite and contiguous to the calyx, 1.5 mm. long, 2 mm. 
broad. Calyx cupulate, toothed, about 5 mm. long, densely 
ferruginous-pubescent, the 2 anterior teeth rounded and 
coalescent, the 3 posterior acute but almost obsolete. 
Petals pink; standard ovate or orbicular, 2-lobulate at the 
base, emarginate at the apex, almost flat, densely silky-hairy 
on the back, the claw 2 mm. long, the blade 10 mm. long, Fic. 27.—Lonchocarpus

pubescent, the claw 5 mm. long, the blade 8 mm. long, 3.5 mm. broad. Vexillar

curved, 3.5 to 4 mm. long, sharply separated from the ovary, hairy almost to the 
tip; stigma capitellate. 
Legume flat, 1 to 4-seeded, coriaceous, glabrescent, 3 to 1] cm. long, 1.7 cm. broad, 
more or less contracted between the seeds, the vexillar margin broadened opposite 
the seeds (nearly 5 mm. broad) and slightly concave. Seeds reniform, flat, dark 
brown, about 11 mm. long and 6 mm. broad. 
Type in the U. 8. National Herbarium, no. 334017, collected at Santo Domingo 
de Osa, Costa Rica, in forests, flowers, March, 1896, by A. Tonduz (Inst. Fis. Geogr. 
Costa Rica, no. 9950). The legume and seeds are described from Pittier 3879, cited

This species is very common in Panama. Besides differing from L. sericeus (Poir.) 
H. B. K. in several details of its general description, the type of the legume is distinct, 
the vexillar margin being concave and broad and not sharply carinate. Consequently
