PITTIER—-MIDDLE AMERICAN SPECIES OF LONCHOCARPUS. 81 
pubescent, the former short (less than 1 mm. long), broad, early caducous, the upper 
ones opposite, suborbicular, about 3 mm. long and broad, appressed to the base of the 
calyx and almost persistent. Calyx truncate, about 5 mm. long, densely grayish- 
pubescent without. Petals purple, with white claws; standard suborbicular, emargi- 
nate at the apex, silky-pubescent on the back, the claw about 3 mm. long, the blade 
15 mm. long and broad, the basal lobules small, callous and revolute; wings oblong, 
auriculate, the claw 5.5 mm. long, the blade 11 mm. long, 5.5 mm. broad, pubescent 
outside along the lower margin, sparsely so on the claw; carinal petals mostly free, 
subauriculate, obtuse, pubescent without and within 
along the lower margin and on the claw, this about 
5 mm. long, the blade 10 mm. long, 5 mm. broad. 
Vexillar stamen free at the base; staminal tube sparsely 
pubescent all over, about 12 mm. long. Ovary short- 
stipitate, linear, 9-ovulate, about 9 mm. long, densely 
grayish-pubescent; style arcuate, sparsely pubescent 
almost to the tip; stigma capitellate. 
Fruit not known. 
Type in the U. 8S. National Herbarium, no. 578330, 
collected near Nahuizalco, Department of Sonsonate, 
El Salvador, at an altitude of 550 meters, in flower, 
February 16, 1907, by H. Pittier (no. 1932). 
Another specimen of the same is Renson 238, col- 
lected in flower near San Salvador. I refer also to this 
species J. D. Smith’s no. 4143, collected along the Rfo

gate racemes. They were determined by the late 
Micheli as L. guatemalensis Benth., an association which is indicated at first sight 
as erroneous on account of the large bractlets contiguous to the calyx. 
Lonchocar pus salvadorensis is related closely to L. sericeus, but differs in the reduced 
number of leaflets, the short, dense, paniculate inflorescences, blossoming before or 
simultaneously with the appearance of the new leaves, the large bractlets, the pubes- 
cence of the petals and staminal tube, the shape of the standard, etc.

A spreading tree 6 to 10 meters high, the trunk 15 to 30 cm. in diameter, the branch- 
lets grayish brown, at first ferruginous-pubescent, lenticellate. 
Leaves 7 to 13-foliolate, the rachis narrowly canaliculate, 8 to 15 cm. long, more or 
less pubescent. Leaflets coriaceous, the petiolules obscurely canaliculate, densely 
ferruginous-pubescent, 5 to 6 mm. long, the blades ovate, oblong, or obovate, rounded 
at the base, obtuse or shortly obtuse-acuminate at the apex, 4.5 to 9.5 cm. long, 2.5 
to 4.5 cm. broad, glabrous or glabrescent and sublustrous above, finely reticulate 
and puberulous beneath, the costa and veins more or less hairy and impressed on the 
upper face, prominent and ferruginous-pubescent beneath. Stipules not seen. 
Racemes solitary on defoliate nodes at the ends of the branchlets, the rachis fer- 
ruginous-pubescent, 12 to 25 cm. long. Peduncles and pedicels ferruginous-pubes - 
cent, the former 3.5 mm. long, 2-pedicellate, the latter about 3 mm. long, each ofien 
bearing 2 or 3 flower buds; bracts and bractlets ovate, ferruginous-pubescent, the 
latter about 2 mm. long, appressed to the calyx. Calyx cupulate, rather narrow, 
about 5 mm. long, densely ferruginous-pubescent, the margin sinuate-dentate. Petals 
diversely colored; standard suborbicular, subemarginate at the apex, densely silky-
