66 CONTRIBUTIONS FROM THE NATIONAL HERBARIUM. 
Type in the U. 8. National Herbarium, no. 258406, collected at El Carrizal, Depart- 
ment of Santa Rosa, Guatemala, at an altitude of about 1,670 meters, in flower, May, 
1892, by Heyde and Lux (J. D. Smith, no. 3289). 
Determined as Lonchocarpus sericeus (Poir.) H. B. K. by the late Micheli, but evi- 
dently belonging to the subgenus Eulonchocarpus, and to be placed near L. luteomacu- 
latus, from which it differs in the number and size of the leaflets, the shape of the 
branchlets, the dimensions of the floral parts, the yellow-spotted petals, etc. 
16. Lonchocarpus oaxacensis Pittier, sp. nov. Ficure 14, 
A tree, the branchlets grayish, lenticellate, at first tomentose. 
Leaves 7-foliolate, the rachis brownish-tomentellous, terete, 6 to 8 cm. long. Leaf- 
lets subcoriaceous, the petiolules thick, 4 to 5 mm. long, tomentellous, the blades 
ovate, rounded and subattenuate at the base, obtuse 
or subacute at the apex, 4.5 to8cm. long, 3 to4.5cm. 
broad, minutely pilosulous and dark green above, 
paler, pubescent, and reticulate beneath, the costa 
and veins subimpressed or prominulous above, 
prominent and fulvous-tomentellous beneath. 
Stipules not seen. 
Racemes axillary and paniculate at the ends of 
the branchlets, the rachis puberulous-tomentellous, 
rather slender, 4 to 12 cm. long. Peduncles and 
pedicels tomentellous, the former biflorous, grow- 
ing singly along the rachis, 6 to 7 mm. long, the 
latter 4 to 6 mm. long; bracts and bractlets linear 
or oblong, very small and fugacious, hairy, the latter 
not very close to the calyx. Calyx cupulate, obso- 
letely 5-toothed, minutely brown-pubescent, about 
6 mm. long, the 2 carinal teeth rounded and subcon-

without, the claw about 2.5 mm. long, the blade 13 mm. long, 15 mm. broad ; wings 
oblique, oblong, obtuse, auriculate, glabrous, ciliate at the apex, the claw about 5mm. 
long, the blade 11.5 to12 mm. long, 5.5 to 6 mm. broad; carinal petals falcate, subauri- 
culate, obtuse, slightly pubescent at the apex, the claw asin the wings, the blade about 
7.5 mm. long and 5.5 mm. broad. Vexillar stamen free at the base. Ovary sessile, 
linear, densely pubescent, about 9 mm. long, 7 or 8-ovulate; style arcuate, glabrous; 
stigma capitellate. 
Legume not known. 
Type in the U. 8. National Herbarium, no. 371944, collected at Jayacatlin, State 
of Oaxaca, Mexico, at an altitude of about 1,500 meters, in flower, April 8, 1895, by 
Rev. Lucius C. Smith (no. 454). 
A beautiful species, related probably to Lonchocarpus latifolius (Willd.) H. B. K. 
and conspicuous for its large flowers. 
17. Lonchocarpus lineatus Pittier, sp. nov. Figure 15. 
A tree, the branchlets grayish, striate, minutely lenticellate, at first ferruginous- 
hairy. 
Leaves (1 to) 5-foliolate, the rachis canaliculate, grayish-hairy, 1.5 to 7.5 cm. long. 
Leaflets submembranous, the petiolules terete, densely grayish-hairy, 4 to 6 mm. 
long, the blades ovate, broadly rounded at the base, obtusely acuminate at the apex, 
4 to 12 cm. long, 2.5 to 5 cm. broad, puberulous or glabrescent above, softly grayish- 
pubescent beneath, the costa and veins grayish-hairy and impressed above, ferrugi- 
nous-hairy and prominent beneath.
