Name: Trisetella didyma (Luer) Luer

Etymology: The genus name Trisetella refers to the three characteristically elongated sepals found in many species of the genus. The specific epithet didyma means “paired” or “twin-like.”

Origin/Distribution: Northwestern South America.

Location/Habitat: Epiphytic miniature orchid of humid montane forests. We recommend shade to bright filtered light, high humidity, gentle, continuous air movement, and intermediate conditions.

Description and Notes: Trisetella didyma is a very compact Pleurothallidinae with small leaves and delicate flowers, whose narrow, elongated sepals give the genus its characteristic appearance. We prefer to grow this species mounted with a little sphagnum moss or in a very fine, airy substrate. The fine roots should remain evenly moist and should not be allowed to dry out completely. Temperatures of about 14–24 °C, high humidity, and good air movement promote healthy growth.
