A species closely related to Lonchocarpus sericeus (Poir.) H. B. K. and ZL. santa- 
rosanus Donn. Smith, differing from both in the pubescence, the shape of the leaflets, 
and the size and indument of the flowers. It comes closer to L. santarosanus in the 
length and shape of the pistil and in the very broad carinal petals, but the ovary is 
3-ovulate and the leaflets are distinct in several details.

A tree 6 to 8 meters high, the branchlets grayish, minutely lenticellate, at first 
pubescent. 
Leaves 11 to 15-foliolate, the rachis minutely pubescent, canaliculate, 15 to 21 
cm. long. Leaflets membranous or subcoriaceous, the petiolules hairy, canaliculate, 
4 to 6 mm. long, the blades lanceolate, oblong, or ovate-oblong, 
rounded or subacute at the base, rather long and acutely acuminate, 
4 to 7.5 cm. long, 1.5 to 2.5 cm. broad, glabrous and minutely reticu- 
late above, beneath paler, densely pubescent, subreticulate, the costa 
and veins prominent. Stipules not seen. 
Racemes axillary, densely flowered, the rachis puberulous, 6 to 12 
cm. long. Peduncles and pedicels hairy, the former 4 to 6 mm. long, 
mostly biflorous, the latter 2 to 3 mm. long; bracts and bractlets 
small, ovate-oblong, pubescent, the latter inserted a little below the 
calyx. Calyx cupulate, truncate, broad, 1.5 to 2 mm. long, pubes- 
cent. Petals scarlet (fide J. D. Smith); standard orbicular, concave, 
silky-pubescent without, distinctly callous-plicate at the base,
