Concept
Trochetiopsis
Summary
The flowering plant genus Trochetiopsis consists of two extant and one extinct species endemic to the island of Saint Helena (South Atlantic Ocean). They were formerly placed in the family Sterculiaceae, but this is included in the expanded Malvaceae in the APG and most subsequent systematics.
There is evidence from fossil pollen that the Trochetiopsis lineage has been on Saint Helena since the late Miocene (some 9.5 million years).
The species of this genus were formerly included in the genus Trochetia, but were separated by Marais in 1981 on the basis of geography and morphological characters. Unlike in Trochetia, the Trochetiopsis flowers have only five stamens, and the sepals generally have appressed sericeous indumentum on their interior faces (although one species, T. melanoxylon, lacks this last character).
The wood of all the species is attractively coloured and is used in island inlay work.
Trochetiopsis is closely related to the genera Melhania and Paramelhania, with a 2021 study subsuming Trochetiopsis and Paramelhania into Melhania.
There are three species (two living, one extinct), and one named hybrid:
Trochetiopsis erythroxylon. Extinct in the wild
Trochetiopsis ebenus. The St Helena ebony (critically endangered in the wild).
Trochetiopsis melanoxylon - Extinct.
Trochetiopsis × benjaminii (T. erythroxylon × T. ebenus).
