Chorizanthe parryi var. fernandina

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], generally hairy. Stem: branches basal or from erect stem, prostrate or decumbent to ascending. Leaf: all basal or basal and cauline, alternate except for bracts, awnless; ocreae 0. Inflorescence: cyme-like, open to +- congested; axes generally 3 from plant base or proximalmost branching node of erect stem, equally or unequally forked; bracts opposite or whorled, entire, generally in whorl of 3 at proximalmost branching node, not distinguishable from basal leaves in plants branched from base, distal generally opposite, proximal leaf-like or some or all scale-like to linear, needle-like, awnless or distal often all awned; involucres sessile, generally solitary at axis forks, distally in loose to dense clusters; involucre tubular, 3--6-ribbed, lobes 3, 5, or 6, equally or unequally awned, awns straight or hooked; involucres at forks often differing from those in clusters. Flower: 1(2) per involucre; pedicel short, included in involucre; perianth glabrous or hairy, white, yellow, pink, maroon, or purple, sometimes 2-colored, lobes (5)6, entire, minutely toothed, or fringed, tip acute, rounded, notched, or 2-lobed; stamens generally 3, 6, or 9. Fruit: generally brown or black, generally ellipsoid, 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 include lobes and awns unless otherwise specified. Chorizanthe minutiflora and C. aphanantha newly described, added; C. eastwoodiae segregated from C. angustifolia.

All markers link to CCH specimen records. The original determination is shown in the popup window.
Blue markers indicate specimens that map to one of the expected Jepson geographic subdivisions (see left map). Purple markers indicate specimens collected from a garden, greenhouse, or other non-wild location.
Yellow markers indicate records that may provide evidence for eFlora range revision or may have georeferencing or identification issues.
