Note
|
The showy tubular flowers of this genus resemble those of Brunfelsia undulata (Solanaceae) or Pose queria latifolia (Rubiaceae) which are also fragrant night bloomers adapted to hawk moth pollination. The roots of Escobedia are used by local peoples as a food coloring agent which resembles saffron.

Note
|
Although Pennell recognized 15 species in the genus, there are fewer than six. In upper Central America, Escobedia laevis Cham. & Schlecht., a species with linear leaves and narrow calyces, occurs in 'marshes, but it has not been found as far south as Panama. Species with broader leaves often occur in drier habitats from Mexico to Paraguay and Brazil. The genus is closely related to the African genus Cycnium Mey. ex Benth. (1846) from which it may not be distinct. Cycnium has been distinguished by the anthers having one theca reduced.
