Ehrend. is a new record for the flora of Egypt. Descriptions, photographs, useful differential morphological characters, and a distribution map are given. Problems of nomenclature and synonymy are discussed. Key Words: Nasturtiopsis integrifolia, Cruciata articulata, flora of Egypt. Introduction Generic delimitation in the Brassicaceae is one of the most difficult and controversial aspects in the classification of the family (Al-Shehbaz, 1984, 1999; AlShehbaz et al., 2006). The characters traditionally used at this rank are few in number, usually 1 or 2 morphological characters. These characters are variable within genera, or conflict with one another in their distribution patterns among genera and may not support natural groups. Fruit morphology has traditionally been used in taxonomic treatments of the Brassicaceae; the problem becomes more difficult among the numerous genera with relatively similar linear-shaped fruits. Therefore, the characters other than fruits such as vegetative, pollen, and seed characters together are of greater significance than fruit alone in distinguishing natural genera and species (Abdel Khalik et al., 2002). Franzke et al. (1998) studied the phylogenetic relationships based on nuclear (ITS) and nuclear coding chloroplast DNA sequences among the genera Cardamine L., Dentaria L., .
