This terrestrial species is found in Venezuela and Brazil. In the Gran Sabana, it is found growing in open, grassy plains in association with Sobralia liliastrum. It has been found near Sarisarinama, as well as on top of Auyan tepui, blooming in February.
The stems are characterized by leaf-bearing sheaths that widen very noticeably in their upper part, giving them the flattened, funnel-like appearance that accounts for the origin of this species' name.

This species was pictured on a Venezuelan stamp on orchid sheetlet III, issued in 1994.
Delfina de Araujo has written that this species is found in the Brazilian state of Roraima and may be in Amazonas.
