Monographs Details: Myrcianthes prodigiosa McVaugh
Authority: Maguire, Bassett. 1969. The botany of the Guayana Highland-part VIII. Mem. New York Bot. Gard. 18: 1-290.

For description see McVaugh. This is still known from the original cohections only, these from the Kaieteur Plateau of British Guiana, and from the Tafelberg, Suriname, at elevations from about 420 to 550 m above sea level. This species is unique in Myrcianthes by virtue of its trilocular ovary and its very large flowers. The 3-flowered dichasium is that of Myrcianthes, however, and the embryo of two somewhat unequal plano-convex cotyledons is typical of the genus.
