Annual to shrub, or non-green root parasite, often bristly or sharp-hairy. Stem: prostrate to erect. Leaf: basal and/or cauline, simple or compound, 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
Annual [perennial herb], bristly to rough-hairy. Stem: ascending to erect. Leaf: cauline, ± petioled, ovate to oblanceolate, entire. Inflorescence: cymes, terminal, 2–3-flowered; pedicels ± spreading to pendent in fruit. Flower: calyx deep-5-lobed; corolla rotate to bell-shaped, lobes spreading, throat appendages erect, glabrous; stamens exserted, filament base dilated, anthers adherent around style, separating in age. Fruit: nutlets ± erect, 4, stout, obovoid, irregularly tubercled, exposed stipe-like basal attachment scar, rim of attachment scar thickened.
4 species: southern Europe, northern Africa. (Latin: ancient name)
