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]

<i>Vanilla polylepis</i> Species of orchid

Vanilla polylepis is a climbing orchid species in the plant family Orchidaceae. It is native to tropical Africa, with a range spanning the width of the continent, from Kenya to Angola. It grows in high-altitude evergreen and swamp forests between 1,200–1,500 m (3,900–4,900 ft) and is often found growing on trees bordering rivers and waterfalls. Plants produce bright green, fleshy stems, 10–12 mm (0.39–0.47 in) in diameter, with large, glossy leaves. White, aerial roots form on the stems allowing the orchids to attach themselves to trees for support. As with many orchids, they produce showy flowers, which in the case of V. polylepis are white and yellow with a pink to maroon blotch. This differentiates them from similar species. They have seedpod-like fruits, called capsules, which produce a distinctive aroma as they dry. They are closely related to the well-known species Vanilla planifolia, whose seed pods are used commercially in the production of vanilla flavouring.

Victor Samuel Summerhayes was an English botanist in charge of the orchid herbarium at Royal Botanical Gardens, Kew for 39 years.
