Geogenanthus

Geogenanthus is a member of the subtribe Dichorisandrinae of the tribe Tradescantieae of the flowering plant family Commelinaceae.

Aerial shoots unbranched and determinate in length, up to 0.75 m, with a terminal rosette of leaves.

In the wild, plants grow on the floor of primary rainforests and possess a shallow underground, short, branching rhizome.

Unlike its closest relatives in the family, Cochliostema and Plowmanianthus,[2] its roots are both tuberous (although weakly so) and actually penetrate the soil.

Flowers consist of 3 green-brown sepals, 3 blue, pink or purple petals fringed with moniliform hairs, 4-6 stamens - the posterior three of which may be bearded with monilifiorm hairs, and 3 connate carpels.
