Rumex crispus
CURLY DOCK


Higher Taxonomy
Family: PolygonaceaeView DescriptionDichotomous Key
Common Name: BUCKWHEAT FAMILY
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: RumexView DescriptionDichotomous Key


Common Name: DOCK
Habit: 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.
Species In Genus: 190--200 species: +- worldwide, 63 in North America. Etymology: (Latin: sorrel) Note: Mature inner perianth lobes generally needed for identification. Species often hybridize.

Rumex crispus L.
NATURALIZED
Habit: Perennial herb (biennial), glabrous; taproot vertical, fusiform. Stem: erect, 4--10(15) dm, often branched above middle. Leaf: blade 15--30(35) cm, 2--6 cm wide, lance-linear to lanceolate, base tapered, truncate, or +- cordate, margin generally entire, strongly wavy, especially near base, tip acute. Inflorescence: terminal, dense, occasionally interrupted in lower 1/2, branches straight or arched; whorls 10--25-flowered; pedicels (3)4--8 mm, thread-like, joints swollen. Flower: inner perianth lobes 3.5--6 mm, 3--5 mm wide, round-ovate to triangular-ovate, base truncate or +- cordate, margin entire to irregularly +- toothed, flat, tip obtuse or +- acute; tubercles generally 3, at least 1(2) larger, > 1 mm wide. Fruit: 2--3 mm, 1.5--2 mm wide, generally red-brown. Chromosomes: 2n=60.
Ecology: Abundant. Disturbed places; Elevation: < 2700 m. Bioregional Distribution: CA; Distribution Outside California: worldwide; native to Eurasia. Flowering Time: All year

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.
