Higher Taxonomy
Family: BoraginaceaeView DescriptionDichotomous Key

Habit: Annual to shrub or small tree, or non-green root parasite, often bristly or sharp-hairy. Stem: prostrate to erect. Leaf: basal and/or cauline, generally simple, generally alternate. Inflorescence: generally cymes, or panicle-, raceme-, head-, or spike-like, generally coiled in flower (often described as scorpioid), generally elongating in fruit, or flowers 1--2 per axil. Flower: bisexual, generally radial; sepals (4)5(10), fused at least at base, or free; corolla (4)5(10)-lobed, salverform, funnel-shaped, rotate, or bell-shaped, generally without scales at tube base, with 0 or 5 appendages at tube top, alternate stamens; stamens epipetalous; ovary generally superior, entire to 4-lobed, style 1(2), entire or 2-lobed or -branched. Fruit: valvate or circumscissile capsule or nutlets 1--4, free (fused), smooth to roughened, prickly or bristly or not.
Genera In Family: +- 120 genera, +- 2300 species: tropics, temperate, especially western North America, Mediterranean; some cultivated (Borago, Heliotropium, Echium, Myosotis, Nemophila, Phacelia, Symphytum, Wigandia). Toxicity: Many genera may be TOXIC from pyrrolizidine alkaloids or accumulated nitrates. Note: Recently treated to include Hydrophyllaceae, Lennoaceae. Wigandia urens added, as naturalized.

Genus: SymphytumView DescriptionDichotomous Key

Common Name: COMFREY
Habit: Perennial herb; root thick, carrot-like. Stem: ascending to erect, internodes winged or not, sharp-bristly. Leaf: generally cauline, sharp-bristly; lower petioled; upper short-petioled to sessile; blade lanceolate to ovate, base decurrent or not. Inflorescence: terminal or axillary, generally peduncled, coiled. Flower: calyx deep-lobed, bristly, expanded in fruit; corolla bell- to +- urn-shaped, throat expanded above tube, appendages 5, alternate stamens, at same level at anthers, lance-linear to lanceolate [or not], papillate; stamens attached on upper tube; style exserted. Fruit: nutlets 1--4, ovoid; tip +- incurved; scar at base, +- flat with thick, ring-like, minute-toothed rim.
Species In Genus: 35 species: Eurasia. Etymology: (Greek: growing together, from putative healing properties) Toxicity: Seeds, herbage TOXIC to humans, livestock from pyrrolizidine alkaloids. Note: Ornamental, folk medicine, cultivated for forage.

Symphytum ×uplandicum Nyman
Stem: 6--10 dm, branched. Leaf: 5--15 cm. Flower: calyx 2--4 mm, to 5.5 mm in fruit, lobes generally linear-oblong, in fruit triangular; corolla 13--16 mm, +- pink, turning purple to blue-purple. Fruit: nutlets 3--4 mm, 2--2.5 mm wide. Chromosomes: 2n=36,40.
Ecology: Wet, open sites; Elevation: < 100 m. Bioregional Distribution: NCo, n NCoRO, ScV (waif in Yolo Co.); Distribution Outside California: to British Columbia, northeastern United States; native to Europe. Flowering Time: May--Jul
Synonyms: Symphytum asperum Lepechin, misappl.
Unabridged Note: A stable, though variable, vigorous hybrid of Symphytum asperum Lepech. and Symphytum officinale (see CalPhoto images from NCo). In United States historically confused with the taller, blue-flowered Symphytum asperum, which appears to be rare in North America.
