Marchanda androgyna Linnaeus, Species Plantarum 2: 1138. 1753.

"Habitat in Italia, Jamaica inter saxorum crepedines." RCN: 8146.

Type not designated.

Original material: Herb. Linn. 1269.11 (LINN) .

Current name: Mannia androgyna (L.) A. Evans ( Aytoniaceae).

Note: Grolle (in Trans. Brit. Bryol. Soc. 5: 544. 1968; Feddes Repert. 87: 208. 1976) treated a Micheli collection in FI as the lectotype but this material was never seen by Linnaeus and is not original material for the name. See comments by Zijlstra (in Taxon 39: 291. 1990) on this name in connection with a proposal to conserve Mannia Opiz.
