Trichoglottis, commonly known as cherub orchids or 毛舌兰属 (mao she lan shu), is a genus of flowering plants in the family Orchidaceae. Orchids in this genus are epiphytic plants with thick roots, relatively thick, fibrous stems and many large, thick, leathery leaves arranged in two ranks. The flowers are usually small and yellowish with light brown or purple markings. The flowers have broad sepals, narrower petals and a labellum which has three lobes and is often hairy. There are about 85 species distributed from tropical and subtropical Asia to the north-western Pacific. Most species grow in rainforest.

Description

Orchids in the genus Trichoglottis are epiphytic or climbing herbs with a monopodial habit, thick roots and straggly or pendulous stems. There are many large, leathery linear to elliptic leaves arranged in two ranks with their bases sheathing the stems. From one to a few relatively small flowers are arranged on flowering stems arising from leaf axils. The flowers are resupinate and commonly yellowish with light brown or purple markings. They tend to be produced sporadically throughout the year and last for about a week. The sepals are free and subsimilar. The petals are also free from each other and slightly shorter than the sepals. The labellum is fixed rigidly to the column, fleshy, pubescent or hairy, formed by three lobes and features a sac or spur.

Taxonomy and naming

The genus Trichoglottis was first formally described in 1825 by Carl Ludwig Blume and the description was published in Bijdragen tot de flora van Nederlandsch Indië.

The name Trichoglottis means "hair tongue", and refers to the type species' pubescent labellum.

''Ceratochilus''

In 2014, Kocyan and Schuiteman moved the former monotypic genus Ceratochilus into Trichoglottis. The sole species of Ceratochilus, C. biglandulosus, is endemic to the island of Java in Indonesia. Though Ceratochilus was never considered to be closely related to Trichoglottis, molecular analysis strongly supported its position as sister to T. pusilla. Rather than excluding T. pusilla, the authors merged Ceratochilus with Trichoglottis.
