This paper deals with a comprehensive taxonomic revision of the family Brassicaceae that was published in 1977 for the Flora of Libya. Since then, there have been no updating attempts in the family. Unfortunately, the flora of Libya, including the family Brassicaceae, is out of date. Recently, names of families and species have been updated [phototaxonomy]. The present study concerns mainly concerned with species of the family Brassicaceae, represented by actual authentic voucher specimens preserved in the national herbarium, Faculty of Science, Tripoli University [ULT]. Thus, species that are not represented by voucher specimens deposited in our herbarium are excluded from this study. Therefor, 69 different kinds of taxa representing 43 genera, 69 species, and 13 subspecies included in this study, compared with 96 species, 59 genera, and 15 infarspecific taxa in the flora of Libya No. 23. A total number of 27 species belonging to 21 genera are excluded of which 5 genera with different species are common in both included and excluded genera; these are Alyssum, Brassica, Enarthrocarpus, Raphanus, and Sisymbrium. The results of this study revealed that the genera Matthiola and Diplotaxis are the most sizable genera with 8 and 4 species, respectively, whereas the genera Moricandia, Enarthrocarpus, Lipedium, Lobularia, and Sisymbrium are represented by 3 species each. Other genera are represented by 1-2 species. Four endemic species reported from Libya are confined to the Sahara; these are Ammosperma variable, Matthiola glutnosa, Oudneya africana, and Savignya parviflora. Variety rubella of the species Capsella bursa-pastoris was treated in this study at the specific level. Names of some species are updated according to Plants of the World Online [POWO]. Original keys to the genera and species within each genus are provided. An annotated list of species follows the generic key. Moreover, 69 species are included with relevant citations, synonyms, distribution of species in Libya, flowering period, and a life forms spectrum are included. In addition to that, an excluded list of 27 different species is also given. Genera and species included in this study are arranged alphabetically.
