Dorstenia alexiteria Linnaeus, Systema Naturae, ed. 10, 2: 899. 1759.

RCN: 993.

Replaced synonym: Dorstenia contrajerva L. var. houstonii L. (1753) .

Type not designated.

Original material: as replaced synonym.

Current name: Dorstenia contrajerva L. ( Moraceae).

Note: This appears to be a nomen novum at specific rank for D. contrajerva var. houstonii L. (1753) . Both names appear to have been based on an illustrated account by Houstoun. Although Berg (in Harling & Andersson, Fl. Ecuador 60: 116. 1998; Fl. Neotropica 83: 198. 2001) indicated Houstoun s.n. (BM) as the holotype, it is most unlikely that Linnaeus could have seen this material and, with the existence of a cited illustration as original material, the Houstoun collection cannot serve as a neotype.
