Trochetia is a genus of flowering plants from the family Malvaceae (formerly in the Sterculiaceae, but this family is now usually subsumed in the Malvaceae). They are endemic to the Mascarene Islands.
The genus was first described by A.P. de Candolle in 1823, who named it in honour of French botanist Henri Dutrochet.
The genus Trochetia consists of scrubs or small trees, which can reach a height from two to eight metres. The hermaphroditic flowers are either white (T. triflora), pink (T. parviflora), or reddish orange (T. boutoniana). They are either single-standing, or grow in a cluster of three flowers. Some species have bell-shaped petals. All plants of this genus are imperiled due to the competition of invasive species, like the guavas from China but also by destruction caused by introduced monkeys and rats. Five species occur on Mauritius and one on La Reunion. The habitat consists of humid forests with a high annual rainfall or mountainous slopes which are directed windwards.
Plants from the genus Trochetia belong to the few plants worldwide that can produce coloured nectar. Some scientists, like the Danish ecologist Jens Olesen assume that this could be linked to bird species which have pollinated this plants in the past and are extinct today. However, recent research has demonstrated that not only do endemic Phelsuma geckos pollinate some of the species, but that they actually prefer coloured over clear nectar. Hence, the 'mystery of the Mauritian coloured nectar' can be considered at least partly solved now. Whether the nectar-feeding birds in Mauritius also react to the coloured nectar as a signal for floral reward remains to be seen.
