Callopsis is a monotypic genus from the plant family Araceae and has only one species, Callopsis volkensii. This plant forms a creeping rhizome and has cordate-ovate leaves that are medium green and glaborous. The inflorescence is typical of the Araceae family, with a white spathe and yellow spadix. The spadix is shorter than the spathe and its male and female flowers are separated shortly. It grows at an altitude of 800 m (2,625 ft) in virgin forest in parts of eastern Africa (Kenya and Tanzania). There have been reports of the species in Cameroon, but these remain unconfirmed.
