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.
