U myriocista is extremely variable in over-all size with a corresponding variation in the size of the corolla. It is very closely related to the North American U. purpurea Walt, with a short, obtuse rather than a long, acute spur. Specimens from Central America and the West Indies appear to be more or less intermediate.
