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.
