Common Name: BORAGE or WATERLEAF FAMILY
Habit: 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.
Genera In Family: +- 120 genera, +- 2300 species: tropics, temperate, especially western North America, Mediterranean; some cultivated (Borago, Heliotropium, Echium, Myosotis, Nemophila, Phacelia, Symphytum, Wigandia). Toxicity: Many genera may be TOXIC from pyrrolizidine alkaloids or accumulated nitrates. Note: Recently treated to include Hydrophyllaceae, Lennoaceae. Wigandia urens added, as naturalized.

Common Name: POPCORNFLOWER
Habit: Annual (perennial herb), generally strigose to spreading-hairy; fibrous- to taprooted, staining red dye present or not. Stem: branched at base or above, < 5 dm. Leaf: 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.
Species In Genus: +- 65 species: temperate western North America, western South America, northeastern Asia, Australia. Etymology: (Greek: sideways pit, from position of nutlet attachment scar) Note: 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.

Habit: Annual, generally +- green, rarely red, staining on stems, leaves. Stem: prostrate to erect, 1--6 dm; canescent, rarely rough or bristly. Leaf: basal in +- rosette, 1.5--5 cm; cauline alternate. Inflorescence: 1+, bracts +- throughout. Flower: calyx 3--6 mm, generally not circumscissile in fruit, lobes erect to spreading (circumscissile, lobes curved over fruit), +- appressed-hairy; corolla limb 2--3 mm diam, appendages pale yellow. Fruit: nutlets (2)3--4, 2--2.5 mm, round-ovate, generally arched, generally weakly attached; abaxial ridge, lateral ridges, cross-ribs narrow; interspaces wide, flat; scar near middle, round.
