Etymology
The name geminiflora, twin flower, was given to the species because the flower usually occur in pairs. Nees, on transferring the species to the genus Dipteracanthus, recognized five Greek-letter entities, namely α, procumbens, β, hirsutior, γ, erectus, δ, subacaulis, and ε angustifolius. None of these have been validly published except β and ε.
