Seed morphological characters and seed coat sculpture of 14 species of Malvaceae were examined to assess systematic implications of seed coat sculpture. These taxa are Malva aegyptia L., M. parviflora L., M. neglecta Wallr., M. nicaeensis All., M. sylvestris L., Lavatera cretica L., Alcea rosea All., Sida alba L., Abutilon theophrasti Medicus, A. pannosum (G. Forster) Schlecht., Abelmoschus esculentus (L.) Moench. Hibiscus sabdariffa L., H. trionum L., and Gossypium barbadense (L.). Seed shape, size and colour as well as outer epidermal cell patterns as seen by SEM, anticlinal cell boundaries and periclinal cell walls sculpture allow the recognition of two distinct groups among studied taxa. Seed coat features indicated both intra-group and inter-group relationships. Recognized groupings do not correspond well with the classical treatments of the Malvaceae, rather they suggest restructuring of tribal and generic taxonomy in the family. One important conclusion of this study is the inclusion of Lavatera cretica L. in the genus Malva as M. linnaei, M. F. Ray.
