Hexalectris colemanii
Hexalectris colemanii, or Coleman's crested coralroot, is a terrestrial, myco-heterotrophic orchid lacking chlorophyll and subsisting entirely on nutrients obtained from mycorrhizal fungi in the soil. It is a very rare species endemic to southern Arizona, known from only three counties. It is closely related to H. revoluta and the two are sometimes considered varieties of the same species.
