Diagnostic Description

Calymperes victoriae Dix. from the Victoria Falls, Zimbabwe, is similar but differs from this species by its oblong leaves that abruptly constrict to a short, spathulate, gemmiferous tip. The costa in section has dorsal and ventral stereid bands and incrassate surface cells. The leaves also have narrow teniolae extending from the leaf base to the thickened margin. Both species grow on wood or bark in moist environments.
