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]
