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.
