Name: Coelogyne trinervis Lindl.

Synonyms: Coelogyne cinnamomea Lindl.; Coelogyne stenochila Hook.f.; Coelogyne rossiana Rchb.f.; Coelogyne pachybulbon Schltr.

Etymology: The specific epithet trinervis means "three-nerved" and refers to three prominent longitudinal keels on the lip.

First description: 1830 by John Lindley.

Origin/Distribution: Widely distributed in Southeast Asia, from Indochina to Malaysia and Indonesia.

Location/Habitat: Epiphytic or lithophytic in humid lowland and mountain forests up to about 1,600 m altitude. We recommend warm to intermediate conditions of approximately 16–27 °C, bright filtered light, high humidity, and good air circulation.

Description and notes: This robust species forms ovoid pseudobulbs, each with two lanceolate leaves. Basal inflorescences bear several cream-white to yellowish, often spicy-scented flowers with cinnamon-brown markings on the three-keeled lip. Water abundantly during growth; coarse bark ensures air circulation at the roots. Water somewhat more sparingly after the pseudobulbs have matured, but do not provide a distinct dry rest period.
