Description:Distribution and Ecology - Damp savannas, usually at low altitudes, British Honduras, Nicaragua, Trinidad, Venezuela, Colombia, British and French Guiana, Suriname and Northern Brazil. This extremely variable species is common on low altitude savannas but the specimens cited by Steyermark from 1830-1920 m, and 1065 m on Alt. Roraima are undoubtedly this species. The leaves are usually linear or narrowly linear but on Maguire, Schulz, Soderstrom & Holmgren 54167 and 54269 from Suriname, Wilhelmina Gebergte, alt 225 and 275 m, some of the leaves (apparently those produced first) are obovate-spathulate. Corolla color is recorded as white, yellow, violet or purple or various combinations of these colors and there is also great variation in flower size, the degree to which the calyx-margin is crenulate and to which the bract margin is ciliate-dentate. The scape base varies from densely hispid to quite glabrous.
