Adenochilus

Diurideae subtribe Caladeniinae

Diminutive terrestrials found individually or forming loose colonies. Rhizome subterranean, horizontal, subsimilar to the erect stems. Stems erect, gracile. Leaves solitary, sessile, shiny. Inflorescences erect, pedunculate, one-flowered, the peduncle equal to or longer than the stems. Flowers with the dorsal sepal concave, forming a hood over the column, the lateral sepals and petals free, spreading. Lip unlobed, recurved, with the callus of rows of erect, finger-like, glandular projections. Column erect, winged along its entire length, the wings extending beyond the anther to form a two-lobed, hooded clinandrium.

From the Greek aden, meaning gland, and cheilos, meaning lip, referring to the callus-covered midlobe of the lip.

A genus of perhaps two species native to Australia (New South Wales) and New Zealand.
