68 CONTRIBUTIONS FROM THE NATIONAL HERBARIUM. 
gray-pubescent, about 6 mm. long, 3-ovulate; style arcuate, pubescent at the base; 
stigma inconspicuous. 
Legume not known. 
Type collected in southern Mexico by Jurgensen (no. 717). 
The above description is based on a specimen in the U. S. National Herbarium, 
collected at Chinantla, State of Puebla, Mexico, in flower, July, 1849, by H. Galeotti 
(no. 3457). 
This very curious species is readily distinguished by its unifoliolate leaves. The 
so-called petiolule is composed of a rudimentary rachis on which the real petiolule, 
about 6 mm. long, is articulated as in those species with the normal type of leaves. 
19. Lonchocarpus cochleatus Pittier, sp. nov. PLaTE 4, C (facing p. 65). 
A tree 4 to 5 meters high, the branchlets grayish, glabrous, minutely lenticellate. 
Leaves 7 or 9-foliolate, glabrous, the rachis slender, canaliculate, 7.5 to 12 cm. long. 
Leaflets coriaceous, the petiolules canaliculate, slender, 7 to 8 mm. long, the blades 
ovate, rounded and subattenuate at the base, obtuse or obtusely subacuminate at 
the apex, 4 to 9.5 cm. long, 2.5 to 4.5 cm. broad, light green on both faces, the costa 
and veins impressed above, the former strongly, the latter scarcely prominent beneath. 
Flowers not known. 
Legume lanceolate or elongate, oblique, attenuate-stipitate at the base, rostrate on 
the carinal side at the apex, light brown with darker margins, glabrous, 1 to 3-seeded, 
when 1-seeded ovate, about 4.5 cm. long and 2.7 cm. broad, subcochleate or shallowly 
concavo-convex, when more than 1-seeded more or less arcuate, up to 13 cm. long, 
constricted between the seeds, the joints cochleate. Seeds, in specimen, immature. 
Type in the U. 8. National Herbarium, no. 385594, collected at El Cabazal, State 
of Guerrero, Mexico, with immature fruits, October 18, 1898, by E. Langlassé (no. 471). 
Distributed as Lonchocarpus violaceus (Poir.) H. B. K., but quite distinct and not 
identifiable with any of the Central American species. Unfortunately the flowers are 
wanting and the seeds undeveloped. It seems to be nearest L. megalanthus Pittier, 
but the rachis of the leaves is canaliculate, the leaflets are more numerous with the 
veins nearer and at a different angle, etc. The fruits of the latter species are not 
known. 
20. Lonchocarpus caudatus Pittier, sp. nov. Puate 4, A (facing p. 65). 
A tree, the branchlets brownish, glabrous, minutely lenticellate. 
Leaves 5-foliolate, the rachis slightly canaliculate, glabrescent, 10 to 12 cm. long. 
Leaflets coriaceous, the petiolules slightly canaliculate, glabrescent, 9 to 10 mm. 
long, the blades ovate, rounded and subattenuate at the base, long-acuminate at the 
apex with a narrow and acute acumen, 6.5 to 12.5cm. long, 3.5 to 6 cm. broad, glabrous, 
the costa and nerves hardly prominent above, glabrescent, subreticulate, the costa 
and veins prominent beneath. Stipules not seen. 
Flowers not known. 
Fruiting racemes axillary, the rachis glabrous or glabrescent, 18 cm. long. Pedun- 
cles and pedicels glabrous or softly pubescent, the former about 4 mm. long, the latter 
about 5 mm. long; bracts and bractlets not seen. 
Legume flattened club-shaped or lanceolate, stipitate, apiculate (i. e., bearing the 
persistent style), glabrous, coriaceous, 1 or 2-seeded, 6 or 10 cm. long, 3 cm. broad, 
the margin thin-edged (the carinal margin slightly broader). Seeds reniform, brown 
with white hilum, 10 mm. long, 6 mm. broad, about 1.5 mm. thick. 
Type in the U. S. National Herbarium, no. 48925, collected between Petlancingo 
and Acatlan, State of Puebla, Mexico, November 20, 1894, in fruit, by E. W. Nelson 
(no. 1998). . 
The long-acuminate leaflets, broader near the base, distinguish this species from 
Lonchocarpus mexicanus and L. megalanthus, to which it is probably closely related. 
To judge by the remnants of the indument on the leaves, these must be densely 
tomentose in the first stages of growth, as in the species of the section Eriophylli.
