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.

Key to Boraginaceae
Annual. Stem: simple to branched, prostrate to erect, fleshy, brittle, angled or winged, glabrous to generally bristly (prickly). Leaf: cauline, lower generally opposite, upper opposite or alternate, generally reduced; petiole generally bristly-ciliate; blade pinnate-toothed or -lobed, generally bristly. Inflorescence: flowers 1 in leaf axils or opposite leaves; pedicels longer in fruit, recurved. Flower: calyx bell-shaped to rotate, sinuses generally with spreading or reflexed appendages; corolla bell-shaped to rotate, white, blue, or purple, spotted or marked or not; stamens included; ovary chamber 1, style 1, generally 1/3–1/2 forked. Fruit: generally 2–7 mm wide, spheric to ovoid, hairy, generally enclosed by calyx. Seed: ovoid, smooth, wrinkled or pitted, with a conic, colorless appendage at 1 end.Key to Nemophila
