PITTIER—MIDDLE AMERICAN SPECIES OF LONCHOCARPUS, 73 
Legume long and slender stipitate, narrow, thin, rounded and mucronate at the 
apex, thin-edged on the carinal margin, glabrous, 4 to 10 cm. long, 0.9 to 1 cm. broad, 
1 to 4-seeded. Mature seeds not seen. 
Type from Mexico. The above description is drawn from specimens collected near 
Bonda, at the foot of the Cordillera de Santa Marta, Colombia, October 23, 1898, by 
H. H. Smith (no. 22). , 
ADDITIONAL SPECIMENS EXAMINED: 
VENEZUELA: Quebrada del Tigre, near Arenales, State of Lara, alt. about 400 
meters, in flower, September 6, 1910, Jahn 187. 
Ecvuapor: El Recreo, Province of Manabf, flowers and young fruits, Eggers 15766. 
GUATEMALA: Gualan, Department of Zacapa, in flower, June 20, 1909, Deam 6367. 
Reported also by earlier collectors from Santa Marta, Colombia, and from Maracaibo 
and the Andes of Trujillo and Mérida, Venezuela. 
The identification of the Guatemalan specimens is doubtful. The racemes are 
sparsely flowered and the rudimentary fruits very short, broad, and pubescent.
