BORAGINACEAE BORAGE or WATERLEAF FAMILY

Ronald B. Kelley, Robert Patterson, Richard R. Halse & Timothy C. Messick, family description, key to genera; treatment of genera by Ronald B. Kelley, except as noted

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. [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.

AMSINCKIA FIDDLENECK

Ronald B. Kelley & Fred R. Ganders

Annual; hairs generally bristly, often bulbous-based. Stem: generally erect, 2–12 dm, generally green. Leaf: basal and cauline, alternate, sessile or lower short-petioled, generally linear to narrow-lanceolate or -oblong, generally not succulent, ± entire. Inflorescence: spike-like cymes, generally ± terminal, tip coiled. Flower: generally radial; calyx lobes 5 or 2–4 (see key); corolla tube generally not constricted, generally orange or yellow (red-orange), appendages generally 0, throat generally open, glabrous, limb on large-flowered taxa generally with 5 dark spots. Fruit: nutlets erect, ± triangular, adaxially generally with exposed elliptic attachment scar, generally with rounded or sharp tubercles.
14 species: western North America, southwestern South America, widely alien elsewhere. (W. Amsinck, patron of Hamburg Botanic Garden, 1752–1831) Self-compatible; often heterostylous; large-flowered taxa generally cross-pollinated, small-flowered self-pollinated.

A. douglasiana A. DC. DOUGLAS' FIDDLENECK
NATIVE
Stem: slender, branched in ± upper 1/2. Leaf: occasionally ± narrow-spoon-shaped. Flower: calyx lobes unequal in width, 2–4 from fusion below middle, notched at tip, margins coarse-dark-hairy, abaxially fine-red-brown-hairy; corolla 14–22 mm, tube 20-veined near base, limb 10–16 mm diam, yellow-orange with 5 dark spots. Fruit: 3–5 mm, gray, dull, cobblestone-like.
2n=12. Unstable shaly sedimentary slopes; (100)150–1600 m. South Coast Ranges, w Western Transverse Ranges. Heterostylous. Mar–Jun [Online Interchange] {CNPS list}
Unabridged note: Amsinckia douglasiana has long been confused with a number of Amsinckia taxa, most commonly Amsinckia menziesii var. intermedia, and occasionally Amsinckia tessellata var. gloriosa or Amsinckia eastwoodiae.
