|discussion=<p>Species 7 (5 in the flora).</p><!--
--><p>Rafinesque’s choice of the name Hexalectris was probably inappropriate because plants in the genus tend to have five or seven crests on the lip (C. A. Luer 1975; J. Liggio and A. Liggio 1999).</p><!--
--><p>Examination of material, both living and preserved, suggests that a species complex exists that involves Hexalectris nitida, H. revoluta, H. spicata in the broad sense, and the Mexican and Guatemalan H. parviflora. This is a complicated group, some plants of each species resembling plants of another species within the complex. Hexalectris spicata var. arizonica possibly is a hybrid-derived taxon from H. nitida and H. spicata var. spicata, or the latter species and H. revoluta (P. M. Catling and V. S. Engel 1993), although plants with cleistogamous flowers of H. nitida are often similar to H. spicata var. arizonica. A number of recent significant range extensions have been noted for H. nitida (V. S. Engel 1987), H. revoluta (R. A. Coleman), and H. warnockii (V. S. Engel 1987; G. A. Salazar-Chavez 1991), suggesting that members of this genus lurk unsuspected over a very large geographic area; they may be more common than currently assumed. Because relatively few herbarium collections have been made for this genus, particularly in the western United States and Mexico, it is clear that more has yet to be understood about the biology and taxonomy of the members of this complicated genus. Based on plastid DNA sequences, it has been estimated that Hexalectris is most closely related to the neotropical genera Basiphyllaea and Bletia (D. H. Goldman 2000; D. H. Goldman et al. 2001).</p>
