Bletia mexicana, the Giant Crested Coral Root, has a very narrow distribution, growing in Trans-Pecos Texas and the mountains of north and central Mexico. This leafless orchid grows up to 60 cm with a dozen or more vivid pink, widely spaced flowers. The margin of the 3-lobed labellum is edged in pink with a white patch and 5 ridges on the center. This orchid prefers leaf litter and humus of moist woodlands.
Bletia mexicana is considered apparently secure, although its distribution appears to be limited.
