“…The identified forms showed notable diversity compared to the other relevant specimens described earlier in relative flora. The plant height of the studied five Forms (27 populations), recorded the highest stem length worldwide (95 cm in Form 2) that supported by EL-Habashy et al (2013) and Boulos (1999). Also, it measures 70 cm in Asian specimens, given by Davis et al (1965), from Turkey (Zohary, 1966), from Palestine and Iraq (Townsend and Guest, 1980).…”

Brassica tournefortii Gouan. (family Brassicaceae) is one of the five species in the Egyptian flora. Its populations showed notable morpho-plasticity with taxonomic debates, which were not yet resolved. The current study was carried out to assess the species morpho-plasticity and its molecular identity based on ISSR. The study was applied to 27 herbarium and fresh populations, representing all the species distribution ranges in Egypt. The taxonomic revision included 70 morphological characters, revealed five distinct Forms (1-5), radical leaf, and fruit provided the major distinguishable traits among the studied 70 morphological characters based on them the morphologic key is provided to delimit these forms. The pollen grain features using SEM are a pioneer at the infra-specific level, two shapes observed the subprolate (Forms 1& 3) and prolate (Forms 2, 4 & 5). Furthermore, the exine micro-features possess taxonomic value at the infraspecific level. The cluster analysis based on ISSR data revealed two clusters congruent to those developed by morphological and pollen traits. The ISSR results indicated that the species morpho-plasticity is genetically controlled. The study highlights the importance of the multidisciplinary approach to assess the taxonomic identity at the infra-specific level, for the auto-taxonomy of morpho-plastic species. Bangladesh J.

Fruit, seed morphology and seed coat sculpturing were recorded for 10 species belongs to 9 genera and five tribes of Brassicaceae in eastern region of Saudi Arabia by using light microscope (LM) and scanning electron microscope (SEM). Four seed patterns were recognized based on surface sculpturing pattern; Reticulate, with four subtypes, undulate, verrucate and ocellate. The results of numerical analysis showed that species were grouped into two major clusters and each cluster divided into two groups. The cluster analysis indicates that the characters of fruit and seed are very important characters for identification and taxonomical classification of the tribes. The results indicate that the most tribes of Brassicaceae are polyphyletic, and some are related to each other's as Lepidieae, Alyssieae and Sisymbrieae.

Several populations of Brassica tournefortii (Brassicaceae) occurring in Egypt are investigated from the micromorphological point of view (seed ornamentations). The species is known to show a notable phenotypic plasticity and five morphotypes was identified in the past. Furthermore, a soil analysis as well as a study of the fungal species from anthers were carried out. The aim of the study is to verify the taxonomic value of the morpholotypes of B. tournefortii and their ecologic relationship with soil variables. The results obtained demonstrated that the five morphological forms can be distinguished based on the seed sculpture. The Canonical Correspondence Analysis (CCA) exhibited a clear correlation between the soil variables and the identified forms. Six species of fungi were detected from the ecto-anthers in the Forms (F2-F4), while F1 was lacking the fungal species. The study revealed that the morphological plasticity of studied B. tournefortii depends on ecological factors.
