Annual to shrub, or non-green root parasite, generally bristly or sharp-hairy.
Stem: prostrate to erect.
Leaf: cauline, often with basal rosette, simple or compound, generally alternate.
Inflorescence: cymes, generally elongate, panicle-, raceme-, or spike-like, generally coiled in flower (often described as scorpioid), generally uncoiled in fruit, or heads, spikes, or panicles, or flowers 1–2 per axil.
Flower: bisexual, generally radial; sepals (4)5(10), fused at least at base, or free; corolla generally (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: nutlets 1–4, free ( fused), smooth to roughened, prickly or bristly or not, or valvate or circumscissile capsule.
± 120 genera, ± 2300 species: tropics, temperate, especially w North America, Medit; some cultivated (Borago, Heliotropium, Echium, Myosotis, Nemophila, Phacelia, Symphytum). Many genera may be TOXIC from pyrrolizidine alkaloids or accumulated nitrates.
