TY - JOUR AU - BOUMAN,, F. AB - Abstract This study has shown for the first time that the middle layer (or layers) of the outer integument is (are) of subdermal derivation in at least some taxa of the Cruciferae. The outer integument is initiated in the Cruciferae in three different ways, viz. subdermally (Brassica, Sinapis), partly subdermally and partly dermally (Lunaria), or completely dermally (Capsella). These differences in initiation are reflected in the structure of the mature testa. The inner integument is completely of dermal derivation and originally two cell-layers thick, but may become more than two-layered during the ovule and seed maturation by periclinal divisions of the inner cell layer. The consequences of the ontogeny of the integuments for the terminology and interpretation of the mature testa is discussed. REFERENCES BELZUNG , E. 1900 . Anatomie et physiologie végétates . Paris .
