Triceratorhynchus is a genus of flowering plants of the orchid family, Orchidaceae. It is native to central Africa: Cameroon, Rwanda, Burundi, Uganda, and Kenya.^[2]^[3]^[4]

Description

Vegetative characteristics

The species are dwarf epiphytes with short stems, which bear many leaves. The leaf shape is oblong or lanceolate.^[5]

Generative characteristics

The inflorescences produce one to many small, spurred, inconspicuous flowers.^[5]

Taxonomy

Taxonomic history

The genus was described in 1951 by the British botanist Victor Samuel Summerhayes (1897–1974).^[2] His concept of the genus only included the type species, which he described as Triceratorhynchus viridiflorus Summerh.^[1] The other two species of the genus were formerly placed in Distylodon Summerh., which is a synonym of Triceratorhynchus.^[2] Therefore, the genus now consists of three species.^[5]^[2]

Etymology

The generic name Triceratorhynchus is composed of the three Greek words tri (three), keras (horn) and rhynchos (beak or snout), which refer to aspects of the floral structure.^[1]

Horticulture

The species of this genus are not cultivated.^[1]
