Facts About

Accepted Synonym: Hexalectris revoluta

Bletia revoluta, the Curly Coral Root, is known from a very few locations in Texas and northern Mexico. This leafless orchid produces about 15 widely-spaced flowers that are purple to tan with darker veins. The sepals and lateral petals are rolled back to form a tight coil, a feature that distinguishes this orchid from other members in the genus that may grow in the same area. The labellum is deeply lobed with crimson veins and white ridges along the central lobe. Bletia revoluta can be found in moist to dry oak-juniper woodlands and has been recorded in the Chisos and Glass Mountains.

Bletia revoluta is considered critically imperiled.


This orchid is autogamous.
