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 to perennial herb, glabrous to rough-hairy; roots generally fibrous. Stem: decumbent to erect. Leaf: basal generally oblong or oblanceolate; cauline generally linear to elliptic. Inflorescence: generally raceme-like cymes, coiled, in age ± open; bracts 0 (leaf-like). Flower: calyx lobes 5, tube hairs appressed to spreading, hooked at tip or not; corolla salverform or wide-funnel-shaped, generally blue, white, or yellow, appendages prominent or not; stamens included; style generally included. Fruit: nutlets generally 4, ± lens-shaped, smooth, shiny, each with raised outer margin, attachment scar adaxially, at base, small.Key to Myosotis
50 species: temperate, boreal. (Greek: mouse ear, from leaf) Myosotis arvensis (L.) Hill reported from Orange Co., 1938, not persisting.

Leaf: sparse, generally 1–4 cm, 2–8 mm wide, abaxial hairs not hooked at tip; basal oblanceolate; cauline ± linear to oblong. Inflorescence: flowers ± in upper 1/2 of plant; bracts 0 (or 1–2 near base); pedicel in fruit < calyx. Flower: calyx 3–5 mm, tube hairs spreading, hooked at tips, also strigose or puberulent-strigose; corolla generally 1–3 mm diam, wide-funnel-shaped, yellow turning blue, appendages prominent, yellow turning red.
