Monographs Details: Tocoyena surinamensis Bremek.
Authority: Maguire, Bassett. 1965. The Botany of the Guayana Highland. Mem. New York Bot. Gard. 12 (3): 1-285.
Description:Distribution and Ecology - Distribution. Known only from Suriname.
Discussion:An examination of the isotype collection shows the corolla-lobes to be rounded or obtuse at the apex, a distinction not mentioned in the original description. The corolla-lobes are 10-11 mm long, 7 m m broad, glabrous within, and densely tomentose without. This species differs from the related T. neglecta N. E. Br. in having smaller corolla-lobes 10-11 mm long and 7 mm broad instead of 25-38 mm long by 13-17 mm broad, broadly triangular calyx-lobes equaling the calyxtube instead of setaceous and shorter than the tube, obtuse corolla-lobes, longer petioles, and glabrous upper leaf-surface.
Distribution:Suriname South America
