Abstract: In this study, the seeds of five Vicia L. (Leguminosae) species were anatomically investigated. The present work deals with the following species: Vicia cracca subsp. cracca L., V. tetraspermae (L.) Schreb., V. hirsuta (L.) S.F. Gray., V. hybrida L. and V. sativa subsp. nigra L. Seed sections (10-15 μm) were obtained and used to establish tissue and cell features. Our data indicate that the seed coat of Vicia species have a rough cuticle surface and a rigid structure. The structure of seed coat shows that there are significant differences among species based on the layers and cell sizes of seed coats.
