Abstract

The systematic position ofCosmocalyx, heretofore treated as agenus incertae sedis, is discussed. The morphological features ofCosmocalyx suggest strong similarities to various genera of the Hamelieae, to which it is compared and where it is placed. A complete description ofCosmocalyx, observations on its phenology, and comments on calyx and fruit development are presented and illustrated.
