Abstract:
A red- and several yellow-flowered variants of Aloiampelos tenuior (Asphodelaceae subfam. Alooideae), a species of
scrambling aloe, are well known, including in cultivation, and apart from the autonymic variety, at least four others have
been given taxonomic recognition at that rank. The yellow-flowered varieties of A. tenuior are predominantly, but not
exclusively, based on vegetative characters, while the red-flowered variety is distinguished by its flower colour, as well as
vegetative characters. The orange-flowered form of A. tenuior, which is much less common in cultivation than A. tenuior
var. tenuior or A. tenuior var. rubriflora, is here described as A. tenuior var. ernstii.
