	ovary - Hutchinson encyclopedia article about ovary
		In botany, an ovary is the expanded basal portion of the carpel of flowering plants, containing one or more ovules.
		In botany, the relative position of the ovary to the other floral parts is often a distinguishing character in classification; it may be either inferior or superior, depending on whether the petals and sepals are inserted above or below.
		The ovaries of female animals secrete the hormones responsible for the secondary sexual characteristics of the female, such as smooth, hairless facial skin and enlarged breasts.

		An ovary is a female reproductive organ in plants that produces ovules.
		For example, the ovary is an organ that produces ovules.

		The oldest seed plants were gymnosperms for the seeds were not yet embedded in an ovary.
		The Rhynie Chert is of equal importance for the understanding of the oldest land plants as the Burgess Shale for animal life.
		Typical of higher plants is that the spores are formed in clusters of four.

		Their remarkable success is due, in part, to the evolution of sophisticated mating control systems that require communication between pollen (the male player in events) and pistil (the female organs, consisting of a stigma on which the pollen lands, the egg-containing ovary, and a style to provide passage from one to the other).
		Flowering plants have the same mating imperatives, but they lack our sensory faculties, are largely immobile, and rely on the vagaries of factors such as wind or insects to assist mating.
		But what mostly sets flowering plants apart from other plants is that their eggs are enclosed in the diploid tissues of the pistil.

		Like other gymnosperms, such as pine trees, cycads produce naked ovules in contrast to the flowering plants in which the ovules are enclosed in an ovary.
		The Zamia genus belongs to the Cycadophyta division of gymnosperms, an ancient lineage of plants that preceded the flowering plants, flourishing during the Mesozoic Era, about 245 to 66.4 million years ago.
		More than 50 species belong to the genus Zamia, small, stocky, fern-like plants native to tropical and subtropical America and the Caribbean.

		The small flowers are unisexual, the male having five almost separate, downy, pale yellowish segments, and the female a single, hairy, glandular, five-veined leaf enclosing the ovary in a sheath.
		In a hot, dry climate, the resin production in the flowering tops of the female plants can be so abundant that even under the midday sun the plants seem to be covered with dew.
		Male plants bear clusters of small flowers, and female plants have persistent hairy bracts and, later, seeds.

	Fabaceae
		The Family Fabaceae (or Leguminosae) is a family of plants in the order Fabales, and one of the largest families of flowering plants with 650 genera and over 18.000 species.
		All members of this family have five-petaled flowers in which the superior ovary ripens to form a pod whose two sides split apart, releasing the seeds which are attached to one seam, alternately attached to one side or the other.
		This is done by symbiotic nitrogen-fixing rhizobium bacteria which colonise the roots of the plants, forming "root nodules".

	MSN Encarta - Tree
		Angiosperms are flowering plants in which the ovule, or seed, is encased in a protective ovary.
		It is divided into dicots, plants with two cotyledons (seed leaf structures), that include the familiar broadleaf trees such as maple and oak; and the monocots, plants with one cotyledon that include the palms and lily trees.
		At maturity, trees are usually the tallest of plants, and their height and single main stem differentiate them from shrubs, which are shorter and have many stems.

	Systematics of the Lyginopterids
		However, "gymnosperms" is also a paraphyletic group characterized by a plesiomorphy of all seed plants - the lack of an ovary.
		It is likely that these groups form a grade, or paraphyletic group, at the base of the seed plants.
		The sister group to the lyginopterids is a clade containing the Medullosceae (another group of former "seed ferns") and all other seed plants.

		The real star is the hairy weevil – it lays eggs in the ovary of the flower and once the larva hatches it consumes the ovary, leaving the plant unable to produce seeds and thereby interrupting the life cycle of the plant.
		Of the 82 trees and shrubs planted, 60 plants — or 73% — germinated and are still alive, which is a 3% increase from last year's plantings.
		We anticipate complete removal of all remaining plants again this summer and will continue monitoring this area to ensure all remaining seeds that sprout are removed prior to setting new seed.

	PBIO 450 Lecture Notes - Dilleniidae -- Spring 1999
		The group may be distinguished by its half-inferior, many-seeded ovary as opposed to the Myrsinaceae (including Aegicerataceae, Ardisiaceae and Embeliaceae) which has a superior, 1-seeded ovary.
		The plants lack a secretory stem in their leaves and stems so that they do not produce a yellowish or reddish-brown sap like the plants associated with the Myrsinaceae.
		The separation of Myrsinaceae and Theophrastaceae into the Myrsinales as done by Takhtajan (1997) is not significant and frankly of little value, the difference being that the myrsinoides are nearly always woody and have mostly fleshy, 1-seeded fruits whereas the primuloids are essentially herbaceous and have dry, many-seeded capsules as their fruit type.

	flowering quince -- Encyclopædia Britannica
		Flowering plants may be divided into three groups, according to the length and pattern of their life cycles.
		The seeds sprout, or germinate, the seedlings develop into flowering plants, new seeds are produced, and the parent plant dies—all in a single growing season.
		The much-branched shrubs or small trees have entire leaves with small stipules and bear large, solitary, white or pink flowers like those of the pear or apple but with leafy calyx lobes and a many-celled ovary, in each cell of which are numerous horizontal ovules.

		The characteristics of the fruit are thus closely related to the characteristic of the flower (or flowers), and especially the ovary (or ovaries) from which it was produced.
		Hint: Fruit is a botanical term used to describe a structure that matures from an ovary, sometimes together with additional tissues.
		The following broad scheme of classification of fruits, which is based on simple, easily observable but superficial characteristics, is artificial; that is, different plants that happen to have the same type of fruit according to this classification are not necessarily related closely.
