Abstract:

As currently delimited, the Brassicaceae comprise 49 tribes, 321 genera, and 3660 species. Of these, 20 genera and 34 species remain to be assigned to tribes. These figures differ substantially from those estimated five years ago, in which 25 tribes, 338 genera, and 3709 species were recognized. Of those 338 genera, 37 are treated herein as synonyms, and 21 genera (10 re-established and 11 new) have since been added. The genera Notothlaspi, Peltariopsis, Sinapidendron, and Xerodraba are lectotypified. The following 11 taxa are reduced for the first time to synonymy of what follows them in parentheses: Boreava and Tauscheria (Isatis), Catadysia (Weberbauera), Coelophragmus (Dryopetalon), Crambeae (Brassiceae), Eremodraba (Neuontobotrys), Leavenworthieae (Cardamineae), Lexarzanthe (Romanschulzia), Noccaeopsis (Noccaea), Romanschulzia orizabae (R. arabiformis), and Sibaropsis (Streptanthus). The new names Isatis zarrei and I. quadrialata are proposed to avoid the creation of later homonyms upon the transfers to Isatis of the herein lectotypified Boreava orientalis and Sameraria nummularia, respectively. Twenty-seven new combinations are proposed: Abdra aprica, Camelinopsis kurdica, Dryopetalon auriculatum, Isatis aptera, I. cardiocarpa, I. glastifolia, I. gymnocarpa, Neuontobotrys intricatissima, N. schulzii, Noccaea apterocarpa, N. caespitosa, N. iberidea, N. oppositifolia, Onuris hauthalii, Parlatoria taurica, Petroravenia friesii, P. werdermannii, Streptanthus barnebyi, S. cooperi, S. hammittii, Tomostima araboides, T. australis, T. cuneifolia, T. platycarpa, T. reptans, T. sonorae, and Weberbauera rosulans.
