Distribution and ecology

The genus contains about 19 species native to South America, Belize, Trinidad and Puerto Rico.[4] Terrestrial or epiphytic plants found in low to mid elevation, hill and mountain forests.

Characteristics

Related to Zygopetalum. Stems short, leafy, usually forming pseudobulbs, 1- to 3-leaved. Leaves petiolate, linear to oblong, narrow, pleated, lightly veined. Inflorescence lateral, erect, slender, branched or unbranched, numerous to few-flowered. Flowers small to medium sized, fragrant, yellow or white, barred magenta, rose or violet and suffused pink on the outside. Sepals and petals subsimilar, free, spreading; lip trilobed with spreading or erect, small side lobes, a larger, broad midlobe that is entire or somewhat bilobed and has a bilobed, erect callus. Column with a conspicuous foot, very short, sometimes winged; pollinia 2 or 4.

Cultivation

Require intermediate conditions, moderate shade, and high humidity. The plants can be grown potted in a free-draining bark mixture and should not be allowed to dry out completely for any length of time.
