Discussion

Specimens of plants from western Louisiana reported as Calopogon pallidus (A. M. Pridgeon and L. E. Urbatsch 1977) are actually C. oklahomensis.

Natural hybrids of Calopogon multiflorus and C. pallidus have been observed in central Florida, and collections of other such hybrids are known from peninsular Florida (D. H. Goldman 2000; D. H. Goldman and L. S. Orzell 2000).

Calopogon pallidus is distinguished by its relatively widely spaced flowers in a long spike, one to three flowers opening simulataneously, lateral sepals typically falcate and reflexed, and petals entire to barely obpandurate and falcate. The blooming period is longer, and C. pallidus flowers later than all species of Calopogon, with the exception of C. tuberosus.
