Tradescantia roseolens
Although E. Anderson and R. E. Woodson Jr. (1935) do not report eglandular hairs on the sepals in Tradescantia roseolens, they are present in nearly all specimens. While some eglandular hairs might be the result of hybridization, in general they seem to be part of the normal variation in this species.
The illegitimate name Tradescantia longifolia Small (a later homonym of T. longifolia Sessé and Mociño 1894) has been used for this species.
