Name: Oncidium planilabre

Etymology: The genus name Oncidium is derived from the Greek onkos for “swelling” or “hump,” referring to the callus on the lip. The specific epithet planilabre is composed of the Latin planus for “flat” and labrum or labium for “lip,” referring to the shape of the labellum.

Origin/Distribution: Andean region of northwestern South America.

Location/Habitat: The species grows epiphytically in moist montane forests. We recommend bright to partial shade with filtered light, high humidity, and continuous air movement. Cool-temperate conditions of approximately 11–23°C during the day and 7–16°C at night are favorable. Prolonged exposure to intense heat should be avoided.

Description and Notes: Oncidium planilabre produces pseudobulbs with leathery leaves and multi-flowered inflorescences. The striking lip is one of the diagnostic features to which the species name also refers. We cultivate the species in a fine to medium-grade, airy orchid substrate that retains some moisture. During active growth, we water regularly with water that is as soft as possible and do not allow the roots to dry out completely. High humidity should always be combined with good air movement.
