Vegetative Morphology

Habit: Caespitose, pseudomonopodial epiphytes.

Main axis: Stems sparsely branched, erect to pendent, leafy throughout, rooting at the base.

Leaves: Leaves alternate, distichous, deciduous by abscission or withering and long-persistent.

Reproductive Morphology

Inflorescence: Inflorescences axillary short-pedunculate, one-flowered scapes, the floral bracts tubular.

Flowers: Flowers one to a few from axils usually near the stem apex, cupped. Sepals and petals free, spreading, subsimilar, subequal. Lip unlobed to three-lobed, clawed, often anchor-shaped, +/- basal callus. Column erect, with a short foot, without wings, the base of the stigma often extended as a tongue-shaped appendage; pollinia 4, in two pairs, on a slender common stipe and minute viscidium. Ovaries smooth, three-angled, or covered with fleshy trichomes (muriculate).

Notes: Dichaea is extremely problematic at the species level. I have little confidence in the application of any names in this flora. In addition, there are many unidentified species in herbaria.
