Terrestrial herbs with erect, often branching stems, glabrous, membranous, plicate,
usually many-nerved leaves with sheathing petioles. Flowers resupinate, small, in terminal
or leaf-opposed bracteate spikes. Sepals connivent; the lateral pair more or less connate,

smaller. Lip superior, adnate to the column, cymbiform or produced into a cylindric
blunt spur, oblong, without side lobes, the apex reflexed, tho disc with short or long
intramarginal ridges or lamell®. Column short or long; the rostellum very long, erect,
often bifid. Stigma single, anticous. Anther erect, dorsal, acute or acuminate, the cells
contiguous; pollinia two, narrow, clavate or cylindric, grooved or even bifid, attached
by a single long slender caudicle to a narrow gland. Capsule cylindric-clavate. Species
