Chorizanthe fimbriata var. laciniata

Higher Taxonomy
Family: PolygonaceaeView DescriptionDichotomous Key
Habit: 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 [1]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.
Genera In Family: 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. Note: 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.

Genus: ChorizantheView DescriptionDichotomous Key

Habit: Annual [perennial herb], prostrate to erect, generally hairy. Leaf: basal or cauline, alternate, linear to narrow, awns 0; ocreae 0. Inflorescence: terminal, generally cyme- or head-like, hairy [(glabrous)]; peduncles 0; involucres generally 1--6, tubular, 3--6-ribbed, teeth 3, 5, or 6, awned. Flower: 1(2), glabrous or hairy; perianth white, yellow, red, maroon, or purple, lobes (5)6, entire, notched or lobed to fringed; stamens generally 3, 6, or 9. Fruit: generally brown or black, generally elliptic, glabrous; embryo straight or curved.
Species In Genus: +- 50 species: temperate western North America; southwestern South America. Etymology: (Greek: divided flower, for perianth lobes) Note: Involucre length measurements including teeth and awns unless otherwise specified. Chorizanthe minutiflora newly described, added.
