Description

The species form a homogeneous group that is well characterized by their striped petals, many-flowered inflorescences and usually ant holes in the twigs. The bracts are recaulescent, which means that the first node of the inflorescence is bare and the lowest bracts are inserted at the second node.[2]

Distribution and habitat

The genus is found in the Guineo-Congolian rainforest zone. The centre of diversity is the Lower Guinean forests; two species occur in the Upper Guinean forests, and only C. angolensis extends into the Congolian forests.[2]

Most species are relatively light demanding, favouring secondary or riverine forest, but some are found in the understory as well. They often grow in clusters.

Taxonomy

At one time, the genus Globulostylis was considered as a subgenus of Cuviera,[3] but it has been re-established as an accepted genus.[2]

gollark: It would be, except you don't really have a full GUI in a shop.
gollark: CC GUIs?
gollark: This does seem like a lot of excessive abstraction.
gollark: ... And then an actual shop eventually?
