Term Definition
Epigynous ovary Referring to a flower in which all or some of the floral parts (i.e., the sepals, petals, and stamens) arise from the summit of the ovary; e.g., species of Asteraceae and Rubiaceae. Epigynous, perigynous, and hypogynous flowers. Drawing by B. Angell.
Hypogynous ovary Referring to a flower in which 1) the sepals, petals, and stamens are free from one another and arise from beneath the ovary, e.g., the flowers of Ranunculaceae or 2) bristles or other structures as well as stamens arise from below the ovary, e.g., the bristles of some species of Cyperaceae and the modified bracts of species of Poaceae. Compare with epigynous and perigynous. Epigynous, perigynous, and hypogynous flowers. Drawing by B. Angell.
Inferior ovary An ovary in which the floral parts (calyx, corolla, and stamens) arise from the summit; e.g., in Rubiaceae and Asteraceae. Superior and inferior ovaries. Drawing by B. Angell.
Ovary The part of the gynoecium (=pistil) containing the ovules. Complete flower. Drawing by B. Angell.
Ovary The part of the gynoecium containing the ovules. Hypanthium and ovary of Eschweilera ovalifolia. Photo by N. P. Smith..
Ovary cross-section A section through the ovary made at a right angle to the long or vertical axis of a flower. A term used in the Lecythidaceae to determine the number of locules and to describe the placention of species and genera. Ovary cross-sections to show placentation. Photo by N. P. Smith.
Ovary half-inferior An ovary of Lecythidaceae that bulges upward at the summit making the ovary appear half-inferior in contrast to an inferior ovary which is truncate at the apex.. Placentation as seen in longitudinal sections of Couroupita guianensis. Photo by C. Carollo.
Ovary inferior An ovary in which the other floral parts (calyx, corolla, and stamens) arise from the summit of the ovary. Medial section of an inferior ovary of Gustavia longifolia. Photo by X. Cornejo.
Ovary summit The area at or above the inside of the staminal ring. Summit of ovary and style of Lecythis holcogyne. Photo by N. P. Smith.
Ovary summit obconical If the summit of the ovary slants upward directly on the inside of the staminal ring (i.e., the summit completely fills the inside of the staminal ring) the summit is obconical. Obconical ovary summits can be narrowly or broadly obconical. Lateral view of an ovary of Eschweilera brevipetiolata. Photo by S. A. Mori.
Ovary summit plateau-like The apex of the ovary sits on a raised plateau characterized by erect sides. Calyx-lobes and ovary summit features. Photo by S.A. Mori.
Ovary summit truncate Appearing to be cut off at the apex, i.e., disregarding the style the summit of the ovary is flat. Truncate ovary summit and geniculate style. Photo by S. A. Mori.
Ovary summit umbonate If the summit of the ovary arches upward directly on the inside of the staminal ring (i.e., the summit completely fills the inside of the staminal ring) the summit is umbonate. See style umbonate. Ovary summit and stigma of Grias haughtii. Photo by X. Cornejo.
Perigynous ovary Referring to a flower in which the sepals, petals, and stamens arise from the rim of a cuplike hypanthium surrounding the ovary. Epigynous, perigynous, and hypogynous flowers. Drawing by B. Angell.
Subsuperior ovary A type of inferior ovary in which the sepals, petals, and stamens do not arise clearly from the apex but instead appear to arise from lower down on the ovary. Epigynous, perigynous, and hypogynous flowers. Drawing by B. Angell.
Superior ovary An ovary of a hypogynous or perigynous flower in which the sepals, petals, and stamens arise from beneath or around the ovary (= hypogynous) or from the rim of a hypanthium (=perigynous). Superior and inferior ovaries. Drawing by B. Angell.
