Morphology
[edit]Aerial shoots unbranched and determinate in length, up to 0.75 m, with a terminal rosette of leaves. The leaves at lower nodes mere tubular leaf sheaths. All plant parts somewhat succulent. 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. Its flowers have no fragrance detectable by the human nose.
