Type in the John Donnell Smith Herbarium, collected in the forested hills around 
Nicoya, Costa Rica, in flower, May, 1900, by A. Tonduz (Inst. Fis. Geogr. Costa Rica, 
nos. 13961, 13966). 
Other specimens (Inst. Fis. Geogr. Costa Rica, no. 13812) were collected in flower in 
the same locality, also by Mr. Tonduz. The fruits accompanying the last specimen, 
in the U. 8. National Herbarium, are all detached. In his description, Capt. Smith 
does not mention the remarkably recurved carinal margin. 
The vernacular name of the species is “‘chaperno.”’ This tree produces one of the 
hardest timbers in the country. 
My reasons for not including this species and the two following in the genus Derris 
are given elsewhere.

Derris nicoyensis Donn. Smith, Bot. Gaz. 44: 111. 1907. 
. A shrub or small tree, the branchlets grayish, glabrous, minutely lenticellate. 
Leaves, 5-foliolate, the rachis glabrous, canaliculate, 7.5 to 10 cm. long. Leaflets
