["Habitat in Vera Cruce."] Sp. Pl., ed. 2, 1: 176 (1762). RCN: 992. Type not designated. Original material: [icon] in Houstoun in Philos. Trans. 37(421): 196, f. 1. 1733. Current name: Dorstenia drakena L. ( Moraceae ). Note: Although Berg ( Fl. Neotropica 83: 203. 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 .
