8. Lonchocarpus affinis Pittier, sp. nov. Puate 1,C. Fiaure 3. 
A tree, the branchlets thick, nodose, the younger parts ferruginous-pubescent. 
Leaves 13 or 15-foliolate, rarely 11-foliolate, the rachis subterete, 19 to 27 cm. long, at 
first ferruginous-hairy, later glabrescent. Leaflets coriaceous, the petiolules 5 to 6 
mm. long, subcanaliculate, ferruginous-hairy, the blades oblong, rounded and sub- 
attenuate at the base, obtuse, acute, or shortly subacuminate at the apex, 3 to 12.5 
cm. long, 1.8 to 4 cm. broad, glabrous and impressed-reticulate above, elevated- 
reticulate and softly pubescent beneath, the costa and veins ferruginous-pubescent 
and impressed above, ferruginous-hairy and very prominent beneath. Stipules 
ovate, ferruginous-hairy, caducous. 
Racemes axillary, mostly paniculate at the ends of the branchlets, the rachis terete, 
10 to 13 cm. long, ferruginous-hairy. Peduncles and pedicels ferruginous-hairy, the 
former usually biflorous, 1 to 2 mm. long, the latter 2 to 3 mm. 
long; bracts oblong, very small, hairy, caducous, the latter a little 
distant from the calyx. Calyx cupulate, about 2.5 mm. long, fer- 
ruginous-hairy, 5-toothed, the two vexillar teeth rounded and con- 
nate, the carinal tooth longer and prominent. Petals purplish, 
turning to white toward the base; standard suborbicular (broader 
~~ than long), concave, bilobulate and callous-plicate at the base, 
SF emarginate at the apex, densely fulvous-pubescent on both sides of 
the median line without, the claw obliquely inserted, 1.5 to 2

Standard; % hairy along the longitudinal veins, the claw about 2.5 mm. long, 
votale, 4 eal the blade 5 mm. long, 2 to 2.5 mm. broad; carinal petals falcate, 
and stamens; e, broadly rounded at the apex, sparsely and minutely ferruginous-

onan the claw asin the wings, the blade 5 mm. long and 3 mm. broad. 
ug ; Vexillar stamen free at the base; staminal tube and filaments glab- 
rous, Ovary linear, sessile, densely fulvous-hairy, about 5 mm. long, 2-ovulate; 
style glabrous, abruptly geniculate, straight and exceeding the stamens; stigma capi- 
tellate. 
Legume lanceolate-elongate, attenuate and short-stipitate at the base, rounded and 
apiculate at the apex, 1 or 2-seeded, 5.5 to 9 cm. long, 1.6 te 1.8 cm. broad, thin and 
submembranous, fulvescent, softly hairy or glabrescent, the vexillar margin narrowly 
3-winged, the carinal margin slightly thickened. Seeds reniform, flat, purplish, about 
10 mm. long, 5 mm. broad. 
Type in the U. 8. National Herbarium, no. 48926, collected at Orizaba, State of 
Veracruz, Mexico, by Botteri (no. 348). 
OTHER SPECIMENS EXAMINED: 
Mexico: Vicinity of Orizaba, in fruit, August 4, 1866, Bourgeau 2834. Near 
Jalapa, Veracruz, May 17 to 22, 1899, Rose & Hough 4278. 
This species agrees closely with Lonchocar pus velutinus Benth. in most details, but is 
specifically differentiated by the number and shape of the leaflets, the pubescence of 
the flowers, the characters of the fruits, and the shape, size, and color of the seeds.

A tree, the branchlets brownish, glabrous, minutely lenticellate. 
Leaves 5-foliolate, the rachis glabrous, canaliculate, 8to 12 cm. long. Leaflets sub- 
membranous, the petiolules canaliculate, glabrous, 7 to 8 mm. long, the blades obo-
