Annual to shrub [tree]. Stem: nodes swollen or not. Leaf: simple, basal or cauline, generally alternate; ocreae present or 0, generally scarious, persistent or not. Inflorescence: flower clusters in axillary to terminal cyme-, panicle-, raceme-, spike-, umbel- or head-like arrangements, entire inflorescence or main inflorescence branches generally subtended by bracts ("inflorescence bracts"); peduncles present or 0; flower clusters in Eriogoneae-Eriogonoideae subtended by involucre of >= 1 free or ± fused, sometimes awn-tipped bracts ("involucre bracts") or, in Polygonoideae and rarely in Eriogonoideae, not (if bracts completely fused, involucre "tubular"); pedicels in Eriogoneae each often subtended by 2 free, transparent, linear bractlets or in Polygonoideae all subtended by 2+ fused, membranous, wide bractlets. Flower: generally bisexual, small, 1–200 per node; perianth parts 2–6, generally in 2 whorls, free or basally fused, generally petal-like, often ± concave adaxially, often darker at midvein, often turning ± red or ± brown in age; stamens 3 or 6–9 in 2 whorls; ovary superior, 1-chambered, ovule 1, styles 1–3. Fruit: achenes, included in or exserted from perianth, generally 3-angled, ovoid or elliptic, generally glabrous.
48 genera, ± 1200 species: worldwide, especially northern temperate; some cultivated for food (Coccoloba, sea-grape; Fagopyrum, Rheum, Rumex) or ornamental (Antigonon, lovechain; Coccoloba; Muehlenbeckia; Persicaria; Polygonum), a few timbered (Coccoloba; Triplaris). Several (Emex; Fallopia; Persicaria; Polygonum; Rumex) are weeds. [Freeman & Reveal 2005 FNANM 5:216–601] Treatment of genera in Eriogonoideae based on monographic work of James L. Reveal. Involucre number throughout is number (1–many) per ultimate grouping, at tips of ultimate branches; flower number is per flower cluster or involucre, unless otherwise stated. Fagopyrum esculentum Moench not naturalized, considered an historical waif (or garden weed ± presently), therefore not treated. —Scientific Editor: Thomas J. Rosatti.
Key to Polygonaceae
Annual to perennial herb; glabrous or papillate and hairy; rhizomed, stoloned, or generally from taproot with a short caudex; occasionally dioecious. Stem: prostrate, decumbent, or generally erect to ascending, often ± ridged, red-brown in fruit, nodes ± swollen. Leaf: generally basal and cauline, alternate, petioled except uppermost cauline; ocreae deciduous to persistent. Inflorescence: axillary or generally terminal, generally panicle-like. Flower: generally bisexual, bell-shaped, glabrous, green, ± pink, or red; perianth lobes 6, persistent, in fruit outer 3 ± inconspicuous, inner 3 enlarged, hardened, ± veiny, covering fruit, midrib of 1–3 often expanded into tubercle; stamens 6; stigmas 3, fringed. Fruit: achene, glabrous, ± black or dark brown to ± red.Key to Rumex
190–200 species: ± worldwide, 63 in North America. (Latin: sorrel) Mature inner perianth lobes generally needed for identification. Species often hybridize.
Perennial herb, glabrous, papillate or not; taproot vertical, fusiform. Stem: erect to arching at tip, 2–6(7) dm, branched, slender. Leaf: blade 4–10(15) cm, (2)3–5 cm wide, lance-oblong to ovate-oblong, narrowed at or below middle or not, base ± cordate, rounded, or generally truncate, margin entire, flat or ± wavy, tip obtuse to ± acute. Inflorescence: terminal, open, interrupted, branches spreading; whorls 10–20-flowered; pedicels 2–5(6) mm, thick, joints swollen. Flower: inner perianth lobes 3–6 mm, 2–3 mm wide except teeth, ovate-triangular to oblong-deltoid, base truncate, margin generally dentate (± entire) with teeth 2–5(9), 0.3–2.5 mm, generally on both sides, tip obtuse to ± acute; tubercles (1)3, equal or not, generally warty. Fruit: 2–2.8 mm, 1.3–2 mm wide, dark red-brown to ± black.
2n=20. Disturbed places, meadows, moist or dry habitats; generally < 1500 m. California; Oregon, Nevada, Oklahoma, Arizona, eastern United States; native to Mediterranean. Highly variable. May–Sep [Online Interchange]
