Abstract We have been studying the floral characteristics for 25 taxa (21 wild and 4 cultivated) of family Brassicaceae aim to search for the interrelationships between the taxa and the possibility of exploiting the results in the separation of species. The anatomy of the flowers was recorded through the vascularization of different whorls of the flower and the possibility of strengthening it in the separation of the species and compare the results of the foregoing, in some studies on the family Brassicaceae. The practical works follow the usual steps in the preparation, stain, draw and photograph the samples. This has been possible to achieve the following: 1. The pedicle vasculature is either continuous siphonostelic in ten taxa or dissected in the remaining studied taxa. 2. The calyx vasculature in the majority of the taxa under investigation is three-traced and dependent. The sepal median bundle arises directly from the central stele either in a form of complex or not. 3. The petal supplied by a single bundle furtherly ramifies in a higher level inside the petal tissue and come from a complex. 4. The number of stamens is either two or six. The vasculature of the stamens is one-traced and either arising directly from the central stele, in the form of a complex or both of them.We have been studying the floral characteristics for 25 taxa (21 wild and 4 cultivated) of family Brassicaceae aim to search for the interrelationships between the taxa and the possibility of exploiting the results in the separation of species.

The vasculature of the ovary; two dorsal, two fused ventral masses and four lateral carpellary bundles (either from the central stele or from the splitting of the dorsal carpellary bundles). 6. The false septum between the two carpels has three forms; open, fused or partially fused with or without bundles. And its rule in the explanation of the bi- and tetra-carpellary theory. 7. There are four types of the nectaries; annular type, 8-type, 4- type and 2-type. Whatever the shape of the nectaries, they are vascularized in the majority of the studied taxa. |
