| This beautiful plant is found in Texas Hill country. Once scattered throughout south-central Texas, this species is now thought to be rare, and has been considered for federal status. The Bracted twistflower is an herbaceous, somewhat succulent waxy annual. It produces beautiful lavender-purple flowers from spring to early summer. Its name is derived from the fact that, located at the bottom of each flower stalk, is a tiny bract. This unique feature distinguishes the species from others in the genus. Indigeneous people and european settlers utilized related species as a food source. (Damude and Poole 1990).
