Plants 20–100 cm or more. Corms globose, 8–22 mm. Leaves: blade strongly curled transversely, linear, 25–50 cm × 3.5–15 mm. Inflorescences green or seldom slightly purple at base, becoming entirely green after flowering, 20–100 cm or more; floral bracts ovate to ovate-lanceolate, subulate, 3–12(–30) mm.

Fla., West Indies (Bahamas, Cuba).
Discussion
Calopogon tuberosus var. simpsonii can be distinguished from the typical variety of the species based on its strongly transversely curled leaves, the frequently narrowed and pale apex of the middle lip lobe, and its habitat in wet, marly soils. Based on morphology and allozymes (D. W. Trapnell 1995) and on nuclear and chloroplast DNA (D. H. Goldman 2000), C. tuberosus var. simpsonii was determined to be a distinct taxon.
