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.

Stem: 2–40 cm, strigose, breaking at nodes or not.
Leaf: generally alternate, generally 0.5–4 cm, ± linear, strigose to sharp-bristled.
Inflorescence: bracted or not; pedicel in fruit generally free from nutlets, generally recurved.
Flower: basal cleistogamous flowers generally 0; calyx generally < fruit, lobes free, not arched over 1 nutlet, with hooked or straight prickles, in fruit ± equal or, if unequal, upper 2 > others; corolla funnel-shaped, white, limb 0.5–2.5 mm diam, appendages white or yellow; style attached to receptacle, unbranched, generally persistent, stigma 1, head-like.
Fruit: nutlets generally 4, generally paired, often dissimilar in shape, ornamentation, margin width, spreading, 1–4.5 mm, generally compressed, marginal prickles straight or hooked at tip.
15 species: to BC, WY, TX, nw Mex; South America. (Greek: comb nut, from bristly to dentate nutlet margins of some species) Nutlets of basal, cleistogamous flowers (present in Pectocarya heterocarpa, Pectocarya peninsularis) unusual, not to be used in key.
Unabridged references: [Veno 1979 Ph.D. Dissertation Univ of California, Los Angeles]
Unabridged note: Fls generally of 1 kind with observable white corolla occurring on the cauline inflorescence sections, except for Pectocarya heterocarpa, Pectocarya peninsularis, which also produce cleistogamous flowers, without an observable corolla, that occur at stem bases and produce nutlet shapes not represented in the diagnostic key.
Stem: prostrate to decumbent, 6–26 cm.
Inflorescence: pedicel in fruit 1.5–3 mm.
Fruit: nutlets 2–3.8 mm, linear-oblong, straight or ± recurved near tip; margin teeth free ± to base, width at base generally << length.
