Oncidium ochmatochilum Rchb.f. (1852), reduced to synonymy under Cyrtochiloides ochmatochila (Rchb.f.) N.H.Williams & M.W.Chase (2001), is a species of orchid. The genus Cyrtochiloides N.H.Williams & M.W.Chase (2001) comprises a small group of Neotropical epiphytes, previously included under a broad concept of Oncidium Sw., with a new, more accurate identity based on DNA. Cyrtochiloides is akin to the mainly South American Cyrtochilum Kunth (1815). After having found its species scattered in Oncidium and several other genera, recently Cyrtochilum received notable acceptance by botanists, primarily based on the molecular discoveries made by Williams and Chase, as well as morphological analyses carried out by Stig Dalström. DNA samples illustrate that Oncidium ochmatochilum Rchb.f. and seve
