Seeds of 54 taxa under 17 genera of the family Malvaceae were examined with scanning electron microscope (SEM) and compared. The variation in seed coat pattern differs from species to species even in infraspecific level. Malva the type genus of this family shows rectangular spermoderm celts and fhese are arranged in scalariform pattern but in M. mauritiana. the epidermal cells coincidentally have developed irregular surface.The difference between the genera Alcea and Althaea, the separation of Dicellostyles jujubifolia from the genus Kydia, placing of Urena sinuata as subspecies of U. lobata and establishing of Abelmoschus tuberculatus var. deltoidefolius have been supported.

Abstract


Seeds of 54 taxa under 17 genera of the family Malvaceae were examined with scanning electron microscope (SEM) and compared. The variation in seed coat pattern differs from species to species even in infraspecific level. Malva the type genus of this family shows rectangular spermoderm celts and fhese are arranged in scalariform pattern but in M. mauritiana. the epidermal cells coincidentally have developed irregular surface.The difference between the genera Alcea and Althaea, the separation of Dicellostyles jujubifolia from the genus Kydia, placing of Urena sinuata as subspecies of U. lobata and establishing of Abelmoschus tuberculatus var. deltoidefolius have been supported.
