Hexalectris spicata

Hexalectris spicata, the spiked crested coralroot, is a terrestrial, myco-heterotrophic orchid lacking chlorophyll and subsisting entirely on nutrients obtained from mycorrhizal fungi in the soil. It is native to Arizona, New Mexico, Texas and Coahuila. It is closely related to "H. arizonica" and the two are sometimes considered varieties of the same species. "Hexalectris spicata" is endemic to the southern half of the United States from Arizona east to Florida and north to Maryland and the Ohio Valley.
