Comparative floral anatomy of some species of Brassicaceae and its taxonomic significance Tantawy, Mohamed E. Husein, Mariam I. Mourad, Magdy M. Abdel-Hameed, Usama K. Adansonia 2021 3 2021-10-19 43 20 223 234 [194,295,1013,1038] Magnoliopsida Brassicaceae Plantae Brassicales 12 233 Tracheophyta tribe Brassiceae  The line of advancement was from  Raphanus sativus(less advanced) to  Eruca sativa(advanced) through the intermediate level (12 studied species).  Eruca sativaexhibits number of advanced characters viz. dissected siphonostele, unsplitting sepal median bundles throughout, the petals vascular supply derived from complexes, the two outer staminal bundles arose from complex shared with nectaries and non-vascularized septum. The primitiveness of  Raphanus sativuswas owing to the sepal median bundles arose from the central stele with further ramification (dependent origin), dependent sepal marginal bundles, petal bundles come from complexes sharing with one organ, fused vascularized septum, the lateral carpellary bundles from the central stele, many ovules and vascularized nectaries( Figs 6; 7).
