Corymborchis flava inflorescence, by Roberto Takase Originally published as Corymbis by Thouars in 1822, then later as Corymborchis in Orch. Ind. Arch. 125 (1855).

Corymborchis is a small genus of very primitive terrestrial orchids like Xerorchis, Palmorchis, and Psilochilus, related to Sobralia. There are 8 species described in literature that range from Central America (Panamá, Costa Rica) to Colombia and Equador. The leaves are alternating and plicate on upright stems.

Corymborchis flava, pictured at left, is native to southern Brazil (Rio Grande do Sul and Santa Catarina states). Photos at left by Roberto Takase, São Paulo, Brazil.
The species is also found in Ecuador. We saw hundreds of these plants blooming in February 2004, at high altitude in the vicinity of Podocarpus National Park, in the southern Ecuadoran Andes.
