PITTIER—-MIDDLE AMERICAN SPECIES OF LONCHOCARPUS. 93 
or 2-seeded and 8 cm. long, 1.6 cm. broad across the seeds. Seeds broadly reniform, 
about 6 mm. long and 8 mm. broad, flat, reddish brown with a light-colored hilum. 
Type in the U. S. National Herbarium, no. 600294, collected in dry forest near 
Mamatoca, at the foot of the Cordillera de Santa Marta, Colombia, altitude about 30 
meters, flowers, April 10, 1899, by Herbert H. Smith (no. 107). 
This beautiful species was distributed under the name of Lonchocar pus sericeus (Poir.) 
H.B.K. A look at the floral racemes shows the simple pedicels, and the pods evi- 
dently are not those characterizing the subgenus Neuroscapha, to which the latter 
belongs. On the other hand, the Santa Marta tree does not seem to correspond to 
any of the species with simple peduncles heretofore described. 
Under the same number, three distinct collections have been distributed, obtained 
February 25, April 10, and August 19, 1899. A note by Mr. Smith on one of the New 
York Herbarium sheets explains that ‘‘this species seems to be rare, flowering prin- 
cipally from February to April. In April, the flowering branches were nearly leafless 
but the rest of the tree was covered with old and young leaves.”’

Section Fasciculati. A tree or a shrub (?), the branchlets terete, glabrous, ob- 
scurely lenticellate. 
Leaves 7 or 9-foliolate, the rachis slender, thickened and darker at the base, canali- 
culate, sparsely pilosulous or glabrescent, 9 to 12 cm. long. Leaflets coriaceous, the 
petiolules canaliculate, glabrous or sparsely pubescent, 4 to 5 
mm. long, the blades oval-elliptic or elliptic-lanceolate, acute 
or slightly rounded at the base, acute-acuminate and mucron- 
ulate at the apex, 2.5 to 7 cm. long, 1.3 to 2.7 cm. broad, dark 
green, sublustrous, and, except on the impressed costa, gla- 
brous above, paler (or subglaucescent), reticulate, and mi- 
nutely pubescent beneath, the costa and veins subglabrous 
and prominent. Stipules ovate, acute, pubescent, 3 to 4 mm. 
long, caducous. 
Racemes axillary, the rachis thick, angular, more or less 
rufous-pubescent, 15 to 30 cm. long, the flowers fasciculate on yg 43, — Lonchocarpus 
thick, short peduncles. Pedicels simple, 3 to 5 mm. long, _ boliviensis. b, Wings; c, 
sparsely pubescent; bracts and bractlets suborbicular, about 1 _—_carinal petals; d, calyx 
mm. in diameter, densely rufous-pubescent, caducous. Calyx 924 stamens; ¢, pistil. 
: . . Natural size. From Rus- 
broadly cupulate, sinuate on the margin, about 4 mm. long, by 2362, 
densely ferruginous-pubescent without. Petals purplish; 
standard subflabellate, attenuate at the base into a short claw, emarginate at the 
apex, about 11 mm. long (without the claw, this 1 mm. long) and 13 mm. broad, 
minutely dark-punctate, pubescent without; wings narrow, arcuate, long-attenuate 
at the base, obtuse and subbilobulate at the apex, sparsely pubescent without, ciliate 
on the lower margin at the base, the claw 4 to 5 mm. long, the blade about 15 mm. 
long and 3.5 mm. broad; carinal petals strongly falcate, attenuate at the base, acute 
at the apex, sparsely pubescent along the lower margin without, the claw + mm. long, 
the blade about 11.5 mm. long, 4 to 4.5 mm. broad. Staminal tube strongly arcuate, 
slightly hairy on the upper side. Ovary short-stipitate, linear, minutely pubescent, 
about 7 mm. long, 16 to 18-ovulate; style long, filiform, broadly arcuate, sparsely 
hairy; stigma capitellate, minutely hairy. 
Fruit not known. 
Type in the U. 8. National Herbarium, no. 32680, collected at the junction of the 
rivers Beni and Madre de Dios, Bolivia, in August, 1886, by H. H. Rusby (no. 2362). 
This species differs from all the others in the section Fasciculati in its numerous 
ovules.
