Annual to shrub, 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, appendages 0 or 5 at top of tube, alternate stamens; stamens epipetalous; ovary 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.
± 120 genera, ± 2300 species: tropics, temperate, especially western North America, Mediterranean; some cultivated (Borago, Heliotropium, Echium, Myosotis, Nemophila, Phacelia, Symphytum). Many genera may be TOXIC from pyrrolizidine alkaloids or accumulated nitrates. [Olmstead et al. 2000 Molec Phylogen Evol 16:96–112] Recently treated to include Hydrophyllaceae, Lennoaceae. —Scientific Editors: Ronald B. Kelley, Robert Patterson, Thomas J. Rosatti, Bruce G.

Key to Boraginaceae
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.Key to Symphytum
35 species: Eurasia. (Greek: growing together, from putative healing properties) Seeds, herbage TOXIC to humans, livestock from pyrrolizidine alkaloids. Ornamental, folk medicine, cultivated for forage.
