Matthiola W.T. Aiton, Hort. Kew. ed. 2, 4: 119. 1812 [nom. cons.].

Tribe: Anchonieae DC.

Notes. – A taxonomically difficult genus of 52 species much in need of thorough systematic and molecular studies throughout its range.

Although the study of JAÉN-MOLINA et al. (2009) is a good starting point, substantial more work is needed to resolve many of the taxonomic problems.
