Tripogandra purpurascens

A genus found in Mexico, not entering the United States, Tripogandra is similar to Tradescantia, but with three large stamens with yellow anthers and three smaller stamens with whitish-lavender anthers; all anthers, however, appear to release pollen. My identification of the species is tentative.
