Aniseia is a small genus of twining flowering plants in the morning glory family, Convolvulaceae (order Solanales). Described by the Swiss botanist Jacques-Denis Choisy in 1834, the genus is native to tropical and subtropical America, where its species grow as herbaceous vines in warm, humid habitats typical of the Neotropical region.
The genus belongs to the large and cosmopolitan family Convolvulaceae, which encompasses roughly 60 genera and over 1,600 species of largely twining or trailing plants. Within this family, Aniseia is a small, relatively obscure genus with around 12 taxa recognised at the species level according to the GBIF backbone taxonomy. Three species are frequently cited in floristic treatments: Aniseia martinicensis, Aniseia argentina, and Aniseia luxurians.
Distribution
Aniseia is native to tropical and subtropical America. The genus spans the Neotropical region, with species recorded across the Caribbean (including Martinique, reflected in the epithet of A. martinicensis) and continental South America (including Argentina, reflected in A. argentina).
Taxonomy Notes
Aniseia was established by Jacques-Denis Choisy in 1834 (published in Mémoires de la Société de Physique et d'Histoire Naturelle de Genève, vol. 6, p. 481). It is placed in the family Convolvulaceae, order Solanales. The genus name Aniseia and its circumscription have been subject to revision; recent work (Athiê-Souza & Buril) has transferred Aniseia luxurians from Moric. into the genus.
