Taxonomic note
Asensi & de Reviers (2009: table 1) note that in their 1906 paper, Gepp & Gepp described L. grandifolia from specimens belonging to two different collections and that in their 1906 paper they realized that these collections actually corresponded to two taxonomic entities and created Lessonia simulans for the second one. Therefore, only part of the 1905 paper (p. 106) is relevant. - (11 April 2013) - G.M. Guiry
