Herbs, terrestrial, sympodial. Roots fasciculate, fleshy, villous. Stems simple, rhizomatous. Leaves few-to-many, basal, petiolate; blade not articulate, convolute, mostly ovate to elliptic, soft. Inflorescences terminal, many-flowered spikes or racemes, erect; scapes bracteate. Flowers resupinate, horizontal, greenish or yellowish green, small; sepals subparallel, distinct or connate at base, forming obscure mentum with base of column or sepaline nectar tube; petals connivent with dorsal sepal; lip clawed, sagittate to cordate, constricted proximal to apex; lateral margins appressed to sides of column; column erect; pollinia 2, clavate-oblong, mealy; stylar canal entrance central; stigma lobes 2, distinct or approximate; rostellum longer than wide; viscidium relatively large, disc-shaped; ovary sessile or subsessile. Fruits capsules.

Distribution

Tropical and subtropical regions, s North America, Mexico, West Indies, Central America, South America

Discussion

Species 70 (2 in the flora).

All species of Cyclopogon except the holotype were placed in the genus Beadlea (L. A. Garay 1980[1982]) because their perianth base was not united into a tube. That characteristic was rejected as a valid generic distinction but the taxon was recognized as Cyclopogon sect. Beadlea (P. Burns-Balogh 1982; P. Burns-Balogh and H. Robinson 1983). The perianth tube character is a matter of degree and not one of presence or absence (D. L. Szlachetko 1993).
