Ouvirandra Thou. = Aponogeton Thunb. (Apon.). Oval (1.), widish, tapering equally to base and tip. Ovary, the hollow chamber formed by the infolded sporophylls, in which the ovules are borne on thickened placentae or cushions. It may be superior (on apex of torus above sta.) or inferior (sunk in torus below sta.) or intermediate, apocarpous (free cpls.) or syncarpous (united), in spirals or whorled, radial or-|-in symmetry. It may be unilocular (i-chambered), or hi- tri- locular, &c. (often simply called multilcc.). The imaginary joins of the cpls. are called the sutures (ventral if at the centre), and the midrib of the cpl. is called the dorsal suture. The placenta may bear one, two or more rows of ovules, or one or two ovules only. The partitions of the ovary are called the septa, and false septa, chambering it into more loc. than normal, are found in Astragalus, Cmciferae, Gaylussacia, Linum, & DIAGRAMMATIC LONGITUDINAL SECTIONS OF FLOWERS, to show types of re- ceptacle, ovary, stigma, &c. A, hypogynous flower with unilocular ovary, parietal placentation, and numerous ascending anatropous ovules with raphe downwards; stigma sessile, bilobed. B, perigynous flower with multi-locular ovary, a\-\\f nlar-en- tation, and numerous horizontal anatropous ovules with raphe ; style with bifid stigma. C, epigynous flower with multi-locular ovary,
