Oreganillo amarillo Wendtia gracilis, photographed by Patricio Novoa.

Belongs within: Rosidae.
Contains: Myrtales, Geraniaceae, Melianthales, Sapindales, Brassicales, Malvales.

The Malvidae is a major clade of flowering plants supported by molecular analysis, defined by Cantino et al. (2007) to include Sapindales, Malvales, Brassicales and Tapisciaceae, but expanded by Wang et al. (2009) to include Myrtales, Geraniales and Crossosomatales (thus maintining the Malvidae as the sister group to the other major rosid clade, the Fabidae). The Malvidae roughly corresponds to the "eurosids II" clade of many studies. Within the Malvidae, the Crossosomatales are a relatively small but morphologically diverse assemblage; members of the Crossosomatales do, however, share a similarly much thickened seed coat (Angiosperm Phylogeny Website).
