17. Canavalia paraguayensis Piper, sp. nov.

cuneate at base, abruptly short-acuminate, rather prominently veined, glabrous 
above, strigillose beneath, 5 to 8 em. long by half as broad; peduncles 
strigillose, as long as the young thyrses; racemes 20 to 25-flowered ; brac- 
teoles orbicular; calyx campanulate, sparsely strigillose, 15 mm. long, the

Type in the Gray Herbarium, collected between Rio Apa and Rfo Aquidaban, 
Centurién, Paraguay, December 10, 1908-09, by K. Fiebrig (no. 4395). 
Paraguay: Asunci6n, Morong 694, 624 (Gray, N. Y.; Morong’s 694 is in the 
Gray Herbarium numbered 649). Cordillera de Altos, Hassler 2951 (Kew). 
Notes on Morong’s 694 were published in the Annals of the New York 
Academy of Science (7: 84. 1892) under the name C. ensiformis (L.) DC., 
but there was associated with it Morong’s 639, which is Phaseolus caracalla L., 
so that the notes are confused.
