		The gynoecium consists of a single compound pistil of 2 carpels, a single style, and a superior ovary with 2 locules, each with usually 2-10 axile ovules in one or two collateral vertical tiers.
		The gynoecium consists of a single compound pistil of 2 carpels, a single 2-cleft style, and an inferior ovary with one locule and one basal ovule.
		The gynoecium consists of a single compound pistil of 2-5 carpels, generally with one style and as many style branches or major stigma lobes as carpels, and an inferior ovary with one locule and usually numerous ovules on 2-5 parietal placentae or 3 locules with numerous ovules on axile placentae.

	Journal of the Torrey Botanical Society: Floral ontogeny of Salpiglossis (Solanaceae) and the oblique gynoecium1 (Site not responding. Last check: 2007-10-16)
		The zygomorphic flowers of Salpiglossis have a gynoecium that is on the median plane and not oblique.
		Because the bilocular gynoecium common to most Asterid families has one abaxial and one adaxial carpel, the gynoecium is said to be on the median plane of the flower when the plane of floral symmetry bisects the two locules (Fig.
		If the gynoecium is on the median plane of the flower, but the entire flower is obliquely oriented, as if rotated 36° with respect to its axillary plane, then with reference to the perianth a sepal or calyx lobe should be in the abaxial position (Fig.

	The ventral carpellary bundle system and the residual stele
		Development of the gynoecium from this stage onwards is less well understood; but apparently, once the distal portions of the locules are initiated, the locular regions become extended basipetally by the differentiation of primary meristematic tissue (Esau, 1965) which is derived from the ring meristem (Plate 7C, Fig.
		During the early development of the gynoecium, the surfaces of the locular region, the ventral surfaces and the future stigmatic region are continuous and outlined as a highly meristematic protoderm layer.
		Morphologically, the stigmatic tissue occupies the free distal surface of the syncarpous gynoecium (Plate 2B, Fig.

	gynoecium
		Typically pistils are ovoid to obovoid or elliptic, and terete in cross-section or with the sides often somewhat irregularly angular by compression owing to their close proximity with adjacent pistils.
		Mayo (1989) defines the style of Philodendron as "that portion of the gynoecium between the base of the stigmatic epidermis and the ovary locules." Typically the style is not obvious, appearing as simply a thickened portion of the pistil apex.
		Carvell (1989) reported that the vasculature of the gynoecium arises from a single trace which divides centrifugally to yield a single branch trace for each locule.

		From the outside to the inside, a complete flower (one with calyx, corolla, androecium and gynoecium) is composed of a ring of leaflike sepals, which together comprise the calyx, a ring of petals, collectively the corolla, the stamens, which are collectively called the androecium, and the pistils, together comprising the gynoecium.
		The gynoecium may be composed of an individual, or a number of pistils.
		Gynoecium: The gynoecium can be composed of a single or multiple pistils, and each pistil can contain a single or multiple numbers of carpels.

		Taxonomical flower features are the flower symmetry, the way in which the carpels are fused and the resulting position of the ovules, also called placentation, and the position of the ovary.
		Normally the gynoecium of angiosperms is composed of several carpels.
		It has to be distinguished between a hypogynous (the perianth is attached to the receptacle below the pistil), perigynous (perianth and stamens are borne on the rim of a concave structure in the depression of which the pistil is borne) or epigynous ovary (blossom seems to arise upon or above the ovary).

		The stigmatic papillae are visible at the top of the gynoecium and the petals are almost visible at the top of the bud.
		Stigmatic papillae are visible though the growth of the gynoecium is delayed relative to the wild-type and is malformed.
		The gynoecium and stamen and petal primordia are visible, but appear delayed compared to the development of the sepals; normally the sepals fold tightly over the developing primordia.

		Clearly there is some kind of trade-off between the ideal form represented by the mathematical curves and the physical necessities of actually producing it, together with the required structural integrity which requires a stalk, and a portion between the gynoecium and the bud where the sepals were attached, and so on.
		The attempt to fit a gynoecium form is very sensitive to the relation between the bud lambda and the actual gynoecium size, and will fail if the lambda is not determined accurately i.e.
