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. [Olmsted et al. 2000 Molec Phylogen Evol 16:96–112] Recently treated to include Hydrophyllaceae, Lennoaceae. —Scientific Editors: Ronald B. Kelley, Robert Patterson, Bruce G. Baldwin, Thomas J. Rosatti.
Key to Boraginaceae
Annual ( perennial herb), generally strigose to spreading-hairy; fibrous- to taprooted, staining red dye present or not.Key to Plagiobothrys
Stem: branched at base or above, < 5 dm.
Leaf: simple, cauline or basal and cauline, 0.5–10 cm, generally smaller tipward, linear to oblanceolate.
Inflorescence: raceme- or spike-like cymes, coiled in bud, generally elongate in fruit; bracts 0–many.
Flower: calyx lobes fused below middle, 2–10 mm in fruit; corolla rotate to funnel-shaped or cylindric, white or white with yellow area, tube generally ± yellow inside, limb 1–12 mm diam, appendages prominent to minute, white to yellow.
Fruit: nutlets generally 4, ± ovate (triangular to ± lanceolate), rarely on narrow stalk or short peg, variously roughened, abaxially generally with central ridge, lateral ridges, cross- ribs, generally tubercled, occasionally prickly or bristly; adaxially keeled above attachment scar, scar on side generally near middle to base, sometimes on bottom or oblique (on angle between side and bottom), generally raised.
± 65 species: temperate w North America, w South America, ne Asia, Australia. (Greek: sideways pit, from position of nutlet attachment scar) Nutlet characters in key generally best for 3 nutlets farthest from stem; yellow on corolla changes to white after pollination.

Unabridged note: Fully mature nutlets needed for identification; in many species nutlet closest to stem often more firmly attached, larger, differently textured, and with completely different attachment scar than other 3; nutlet characters used in key focus on 3 more loosely attached nutlets. Intergradation common in some species groups; reticulate speciation in genus; sect. Allocarya often treated as separate genus; many species need study. Corolla size can diminish markedly during flower period. Yellow corolla appendages and, if present, contrasting yellow corolla centers, change to white after successful pollination.
Stem: prostrate to decumbent, 1–3 dm, rooting at nodes.
Leaf: cauline, lower 4–8 cm, upper opposite or alternate.
Inflorescence: bracts 0.
Flower: calyx 4–5 mm; corolla limb 5–10 mm diam.
Fruit: nutlet ± 1.5 mm, ovate; abaxial cross- ribs irregular or netted; scar near middle, ovate or triangular. [Online Interchange]
Fruit: nutlet gray; abaxial cross- ribs irregular, ± = interspaces.
Uncommon. Moist, alkaline places in sagebrush scrub; 1200–1700 m. se High Cascade Range, ne High Sierra Nevada, Modoc Plateau (except Warner Mountains);
