Calopogon

Arethuseae subtribe Bletiinae

Terrestrials arising from corms. Leaves basal, plicate, erect, linear-lanceolate. Inflorescences erect, terminal, long-scapose racemes, the floral bracts insignificant. Flowers not resupinate, showy, pink. Sepals and petals free, spreading. Lip three-lobed, the lateral lobes basal, minute, the midlobe with a beard of long trichomes (pseudopollen). Column elongate, arching, with large apical wings, without a foot; pollinia 4, in two pairs, granular.

From the Greek kalos, meaning beautiful, and pogon, meaning beard, in reference to the trichomes on the lip that mimic a cluster of anthers (pseudopollen).

A genus of four species in eastern North America and the West Indies.
