Intendencia de Choco: Truando, Schntt, no. 3 (Field Mas., phot. Gr.). 



A species clearly of the genus Eupaforium, yet somewhat anomalous 

 in the supernumerary ribs of the achenes.

Originally described from material collected by Dombey in South 

 America, presumably in Peru. The type in the DeCandollean Her- 

 barium was examined some years ago by the writer and there is a 

 clear photograph of it in the Gray Herbarium. With this, as well as 

 with the original diagnosis, the Colombian plants just cited corre- 

 spond closely in all significant details.

 coarsely serrate, 2-4 cm. long; corymbs few -headed; heads many- 

 flow'ered; involucral scales more than 20, linear-lanceolate, acuminate, 

 glabrous or glandular-puberulent, almost equal. — Bonplandia, iv.
