COSTA RICA.—EI Tablazo, Apr. 28, 1946, Jose Antonio Echeverria 358 (UC). 
The slender filaments longer than the anthers, slender anthers sparingly 
punctate dorsally, persistent matted tomentum of undersurface of leaves, and

The Costa Rican collection is a very poor specimen with young buds and loose 
fruits. Although it appears referable here, the leaves are exceptionally large
