Lamarck’s new species of Mesembryanthemaceae and the types of their names

Abstract

The holotype of Mesembryanthemum echinatum Lam. is an unpublished, sketchy drawing kept in the Lamarck herbarium (P-LAM). The holotype of the name M. vaginatum Lam., which has not been taken up again since its original publication, is also in P-LAM. That name has priority over M. ciliatum Aiton, pertaining to a species currently placed in Brownanthus.Two new combinations are proposed: Brownanthus vaginatus (Lam.) Chesselet & M.Pignal and Brownanthus vaginatus subsp. schenckii (Schinz) Chesselet & M.Pignal.
