Heteranthera diversifolia Vahl, Enum. Pl. 2: 44. 1805. Lectotype (designated here). GUIANA. s.loc., fl., s.dat., L.C. Richard s.n. (C barcode C10017422!).

Distribution.

Antilles (Cuba, Dominican Republic, and Puerto Rico), Central America (Belize, Costa Rica, El Salvador, Guatemala, Honduras, Nicaragua and Panama) and South America (Bolivia, Colombia, Ecuador, French Guiana, Guyana, Suriname, Venezuela and Brazil - states of Acre, Amazonas, Amapá, Pará, Rondônia, Roraima, Tocantins, Alagoas, Bahia, Ceará, Maranhão, Paraíba, Pernambuco, Piauí, Rio Grande do Norte, Sergipe, Goiás, Mato Grosso do Sul, Mato Grosso, Minas Gerais and Rio de Janeiro).

Nomenclatural notes.

When describing Heteranthera diversifolia , Vahl (1805) makes no direct mention of any analysed specimens in which he might have based the description of his new species. The author only mentions that his new species is native to Guiana and was sent to him by “Richard”. After analysing the collection at C, we came across a specimen part of Herb. Vahlian., collected by Richard s.n. and identified in Vahl’s handwriting as H. diversifolia . Thus, it is chosen by us as the lectotype.
