Discussion:Our first Venezuelan representative of the genus Candylocarpon connects C. hirlellum with C. pubifloruin Muell.-Arg. Isotypes of both are at The New York Botanical Garden (Esperanga and "propc Barra," respectively). The two seem to differ principally in the character of the indumentum. C. hirteihon is more densely pubescent, the hairs on the stem spreading instead of appressed, the leaves subronnded at base instead of obtusely cuneate, the petiole slightly shorter, about 5 mm long instead of 8 mm. The Rio Yatua specimen has the hairs on the stem dense and spreading- as in C. hirtellum, but the leaves obtuse at the base and with longer petioles as in C. pubiflorum; the peduncles are shorter as in C. pubiflorum. Perhaps the two are not specifically distinct.
