Term:
Ovary summit obconical
Ovary summit obconical
Definition:
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.

Notes:
In Lecythidaceae, this term refers to the summit as it appears immediately on the inside of the staminal ring; if it is flat on the inside between the staminal ring margin and the style base it is called truncate; if it has erect sides immediately on the inside of the staminal ring it is called plateau-like; if it slants upward immediately on the inside of the staminal ring and is not distinguished from the style base it is called obconical; and if it arches upward on the inside of the staminal ring and is not distinguished from the style base it is called umbonate. In a plateau-like summit, the area sitting on the plateau is called an ovary apex and that can be either obconical or umbonate.
