Apical placentation | A type of placentation in which the ovules are attached at the apex of the locule. See placentation. | |
Axile placentation | A type of ovule arrangement in which the ovules arise from placental tissue derived from the apices of the septa of a locule. In this type of placentation the apices of the septa are fused or in very close proximity to one another. | |
Basal placentation | A type of placentation in which the ovules arise from the base of the locule. | |
Laminar placentation | A type of parietal placentation in which the ovules arise along the surface (rather than the margins) of the carpels. Compare with marginal placentation; see placentation. | |
Marginal placentation | A type of parietal placentation in which the ovules arise along the margins of the carpel. Compare with laminar placentation; see placentation. | |
Parietal placentation | A type of placentation found in compound, unilocular ovaries in which the ovules arise from placentae inserted on the wall of the locule near the sutures. | |
Placentation | In broadest terms, the arrangement of ovules within the ovary. See axile, basal, free-central, and parietal placentation. | |
Placentation basal | A type of placentation in which the ovule is attached to the floor of the locule. | |
Placentation free-central | A type of placentation in which the ovules are borne on a central column arising from the base of a unilocular ovary. |
