Trochetiopsis
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). Description. 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. Phylogeny. "Trochetiopsis" is closely related to the genera "Melhania" and "Paramelhania," with a 2021 study subsuming "Trochetiopsis" and "Paramelhania" into "Melhania". Species. There are three species (two living, one extinct), and one named hybrid:
