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. Baldwin, David J. Keil.
Key to Boraginaceae
Perennial herb (biennial); hairs appressed to spreading; caudex generally branched in age, often ± woody, taprooted. Stem: ascending or erect. Leaf: lowest petioles generally ± = blades, ± winged, others 0. Inflorescence: coiled cymes, generally > 3, generally terminal and axillary, ± bracted; pedicel in fruit elongated, recurved to reflexed. Flower: calyx deep-5-lobed; corolla rotate-salverform, generally white with yellow patch adaxially, lobes appendaged near base. Fruit: nutlets erect, > style, attachment scar lateral-medial, generally with barb-tipped prickles abaxially and on margin.Key to Hackelia
40 species: generally western North America, southeastern Asia. (J. Hackel, Czech botanist, 1783–1869) Values for corolla limb diam take into account shrinkage during flower period. Difficult, study needed, especially in northern California, southeastern Asia; sometimes merged with Lappula.

Unabridged note: In North America filling old-world role of flat-flowered forget-me-nots, Myosotis, Lepechiniella, etc, for pollinators.
Stem: generally many from ± stout, woody caudex, 3–11 dm; hairs generally 0 to ± sparse, at mid-stem generally ± spreading, generally > 1 mm. Leaf: basal 6–33 cm, 0.7–3.7 cm wide, narrow-elliptic to oblanceolate, ± green at flower; lower cauline generally 5–23 cm, 0.6–2.4 cm wide, hairs ± appressed, strigose to rough, generally < 1 mm, occasionally > 1 mm on margins; mid to upper cauline generally elliptic, base tapered to obtuse, not ± clasping. Inflorescence: ± wide, ± strigose; pedicel 5–12 mm in fruit. Flower: calyx 1.5–2.7 mm; corolla tube generally = calyx, throat open, limb (4)5–8(11) mm diam, blue, appendages wider than long. Fruit: nutlets 3–5 mm, abaxial prickles generally 4–10, < marginal.
2n=24. Meadows, streambanks, shrubby slopes, open forest; 1200–3500 m. Klamath Ranges, High North Coast Ranges, High Cascade Range, High Sierra Nevada, Modoc Plateau, n East of Sierra Nevada (Sweetwater Mtns); western North America. Jun–Aug [Online Interchange]
Unabridged note: Most commonly collected Hackelia in California, in widespread, ± expansive populations. California Floristic Province plants tend to have smaller corollas than those farther northern and e, where other larger-flowered Hackelia species, such as Hackelia nervosa and Hackelia amethystina, are lacking; corolla size does not distinguish from Hackelia floribunda in Sierra Nevada.
