Oncidium abortivum

An Andean Oncidium (once split into Heteranthocidium) with long branched inflorescences in which many flowers stay small and undeveloped. It grows as an epiphyte in montane forest around 1,800 m, so it wants intermediate-to-cool, humid, airy conditions with steady moisture all year.
