	Polygonaceae
		It is a medium-sized family, with 30 genera and 750 species, most of which occur in the north temperate region of the world.
		The flowers of the Polygonaceae are usually small, radially symmetric, and white, greenish, or yellowish.
		The perianth is undifferentiated or poorly differentiated, and consists of 3-6 persistent sepals.

	Polygonaceae - LoveToKnow 1911
		POLYGONACEAE, in botany, a natural order of Dicotyledons, containing 30 genera with about 700 species, chiefly in the north temperate zone, and represented in Great Britain by three genera, Polygonum, Rumex (Dock, q.v.) and Oxyria.
		They are mostly herbs characterized by the union of the stipules into a sheath or ocrea, which protects the younger leaves in the bud stage (fig.

	Polygonaceae - Wikipedia, the free encyclopedia
		The Polygonaceae, or the Knotweed Family, are a group of dicots including buckwheat, sorrel (but not wood sorrel), rhubarb, and knotgrass.
		It is named for the shape of the seed; that of rhubarb, for example, has a triangular cross-section.
		In the Cronquist system, the Polygonaceae were given their own order, but newer systems treat them as part of the Caryophyllales.

		Most researchers concluded that six tepals is the primitive condition in the family (R. Laubengayer 1937), but A. Lamb Frye and K. Kron (2003) concluded that five tepals is the primitive condition, and that taxa with six or four tepals evolved multiple times within the family.
		In some genera of Polygonaceae, the outer tepals are connate and form a slender, stipelike hypanthium base above the articulation with the true pedicel.

	Polygonaceae (Site not responding. Last check: 2007-10-08)
		The Polygonaceae is a family of annual or perennial herbs or small shrubs with (usually) opposite leaves and uaually with a papery structure formed from a pair of stipules sheathing the stem called an ocrea (not present in Eriogonum).
		The flowers of the Polygonaceae are usually bisexual, generally small but in large inflorescences.
		The sepals and petals are often in 3's or 6's (but sometimes in 4's or 5's) and are often green or dark reddish-brown.

	Introduction to the Polygonaceae
		The Polygonaceae are a group of about 30 to 50 genera and more than 1000 species of caryophyllid flowering plants that are closely related to the Plumbaginaceae.
		For this reason, and because they differ from typical caryophyllids in other ways, there has been debate for a long time about the relationship of the Polygonaceae to the other caryophyllids.
		Most species of Polygonaceae are herbaceous and grow in temperate regions of the Northern Hemisphere, though Coccoloba is usually woody and is found in tropical Mesoamerica.

		The Polygonaceae or Buckwheat family: This family’s scientific name is derived from the Greek words; poly meaning "many" and goni meaning "joint", a reference to many species that have swollen stem-nodes or joints.* The family includes nearly a thousand species.
		Polygonaceae typically have heads made up of tight clusters of small flowers.
		Polygonaceae are common at all elevations in Idaho.

		Two big distinguishing characteristics between wild buckwheat and the two bindweed species are (1) wild buckwheat is an annual and the bindweeds are perennials, and (2) since wild buckwheat is in the Polygonaceae family it has an ocrea that surrounds the stem at the base of each leaf, where the bindweeds do not.
		Another perennial in the Polygonaceae family that can be a problem in agronomic crops, especially in no-till situations, is curly dock.
		Remember that since it is a member the Polygonaceae family, it will have an ocrea at the base of the leaves.

	Caryophyllales
		Purple-spored smuts and Uromyces rusts parasitize several families, including Plumbaginaceae, Polygonaceae and core Caryophyllales (Savile 1979b: he considered this to be a strong sign that the groups were close).
		The flowers of Polygonaceae are rather small, all parts (bar the carpels) are more or less free, and the 5 or 6 tepals are persistent or enlarged in fruit; the achene itself is often angled.
		It has been thought that the flowers of Polygonaceae are basically 3-merous; the carpels are opposite the outer perianth whorl when the perianth is 3 + 3.
