PITTIER—-MIDDLE AMERICAN SPECIES OF LONCHOCARPUS. 75 
broad, minutely reticulate and pilose or pilosulous on the costa and veins above, paler 
and sparsely pubescent beneath. Stipules small, ovate, cano-pubescent, caducous. 
Racemes axillary, the flowers scattered, the rachis sparsely pubescent, 5 to 9 cm. 
long. Peduncles sparsely pubescent, biflorous, about 2 mm. long; pedicels densely 
pubescent, 1 to 2 mm. long; bracts and bractlets pubescent, ovate-oblong, the latter 
opposite and close to the calyx. Calyx cupulate, subtruncate, silky-pubescent with- 
out, about 2.5 cm. long. Petals purplish, all minutely pubescent at the apex; 
standard orbicular, very concave, subbilobulate and emarginate at the base, emarginate 
at the apex, the claw 1 mm. long or less, the blade about 8.5 
mm. long and 9 mm. broad, the basal lobules and lateral mar- 
gins inflexed; wings adhering to the keel, elongate, auriculate, 
the claw 2 mm. long, the blade 6.5 to 7 mm. long, 2.3 to 3 mm. 
broad; carinal petals cohering or free, obovate-oblique, broadly 
obtuse at the apex, the claw asin the wings, the blade about 5 
mm. long, 2 to 2.5mm. broad. Vexillar stamen free at the base. 
Ovary linear, densely white-pubescent, about 4.5 mm. long, 
5-ovulate; style strongly arcuate; stigma capitellate, subbilobu- 
late. 
Legume obovate or elongate, long attenuate stipitate, rounded 16. 25.—Lonchocarpus

Type in the John Donnell Smith Herbarium, collected on the strand belt at Salinas 
Bay, Guanacaste, Costa Rica, in flower, June, 1890, by A. Tonduz (Inst. Fis. Geogr. 
Costa Rica, no. 2731). s 
ADDITIONAL SPECIMENS EXAMINED: 
Costa Rica: Around Orotina, near San Mateo, in flower, June 15 to 17, 1906, 
Maxon 578. Around Nicoya, on wooded hills, in fruit, December, 1899,

Capt. Smith gave this species a manuscript name but afterward referred it to 
L. atropurpureus Benth. Although undoubtedly very closely related to that species, 
its distinctness is quite evident and fully supported by the characters of the fruit, 
which Capt. Smith had not seen. The leaflets are almost always 7, narrowly and 
almost acutely acuminate, not obtuse or shortly obtuse-acuminate; furthermore, 
while in L. atropurpureus the groove of the petiolules is broadly open, it is closed and 
subtubular in the new species. The flowers are slightly smaller, the pubescence of 
the petals is more marked, and the standard is of a distinct shape at the base. The 
legume is much broader and does not seem to contain more than 2 seeds. But for 
the fact that L. parviflorus Benth. is described as having almost always 5 leaflets, 
whereas the leaves of the Costa Rican tree usually show 7, I should feel inclined to 
refer the latter to that species. 
The specific name calyculatus, suggested by Capt. Smith, is hardly applicable 
to a Lonchocarpus, since there is no involucre of bractlets imitating a calyx, hence 
with his courteous consent I have dropped his name and designated the species from 
one of the localities at which it has been collected.
