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.
± 120 genera, ± 2300 species: tropics, temperate, especially western North America, Mediterranean; some cultivated (Borago, Heliotropium, Echium, Myosotis, Nemophila, Phacelia, Symphytum, Wigandia). 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. Wigandia urens added, as naturalized. —Scientific Editors: Ronald B. Kelley, Robert Patterson, Thomas J. Rosatti, Bruce G. Baldwin, David J. Keil.
