Seed exomorphic characters of 32 taxa of Brassicaceae were investigated by LM and SEM. The diagnosticcharacterts at the generic and specific level are, seed shape, dimensions, colour, epidermal cells, and seed coat surfaceand aspect of anticlinal and periclinal walls. Seed shape among the studied taxa showed wide range of variations.LM revealed most of the studied seeds vary from globose to oblong-ellipsoid or elongate. Most of the seeds have nowings except Farsetia aegyptia. SEM investigation at higher magnifications revealed main six types of seed surfacesculpture; reticulate, ocellate, foveate, papillate, stellate and domate. The seed exomorphic criteria obtained from LMand SEM were analyzed by the STATISCA program package using the UPGMA clustering method. Produced datafacilitate the construction of a dendrogam between the studied taxa. Two groups are represented from the first groupincluded the taxa of Tribe Arabideae, Lepidieae, Matthioleae, Sisymbrieae, Alysseae, Chamireae, Schizopetaleae,Stenopetaleae, Drabeae, Euclidieae, Lunarieae, and Streptantheae. The second group included the most commonlyknown genera of the tribe Brassiceae. (PDF) Seed Morphology and Seed Coat Sculpturing of 32 Taxa of Family Brassicaceae.
