This revision showed the presence of four genera Boscia, Capparis, Cadaba and Maerua. Species delimitation in Capparis was re-evaluated, resulting in the recognition of four species of Capparis: C. decidua (Forssk.) Edgew, C. sinaica Veill., C. spinosa L. (with three varieties viz., spinosa, canescens and deserti) and C. orientalis Veill. The last species is proposed to be elevated from var. inermis to the species level. Our results revealed also that leaves, stipules, flowers and fruit characters are of significant taxonomic value. A key for identification of the genera, species and varieties is provided. Type, synonyms, and selected specimens for each species are also presented.

To study a geographically defined subset of the species is common practice but often does not allow assessment of whether or not the geographic group is a natural or monophyletic group and this limits the conclusions that can be drawn. Preconditions for such studies are a broad taxonomic knowledge of the group and a well-supported phylogeny if the species are to be put in proper context. The present project is a part of an international collaboration involving Reading University, UK, and Suez Canal University, Ismalia, Egypt to reconstruct evolutionary and phylogenetic relationships within Egyptian Salvia species. To elucidate the phylogenetic relationships among Egyptian Salvias, we conduct a molecular phylogenetic analyses of two chloroplast DNA (cpDNA) regions (psb-A:trnH) and the intergenic spacer of (trnL:trnF) and one nuclear DNA (nrDNA) region (Internal transcribed ...

It is a more detailed revision to the Egyptian species of Cleomaceae, including morphological descriptions based on a large amount of herbarium material that has been checked. The geographical distribution of the studied species varies greatly. This paper recognized 10 species of Cleome, and also adds further evidence for the suggestion that Cleome gynandra is closely related to Cleome hanburyana.
