Amsinckia intermedia
COMMON FIDDLENECK

Higher Taxonomy
Family: BoraginaceaeView DescriptionDichotomous Key

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.

Genus: AmsinckiaView DescriptionDichotomous Key

Common Name: FIDDLENECK
Habit: 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.
Species In Genus: 14 species: western North America, southwestern South America, widely alien elsewhere. Etymology: (W. Amsinck, patron of Hamburg Botanic Garden, 1752--1831) Note: Self-compatible; often heterostylous; large-flowered taxa generally cross-pollinated, small-flowered self-pollinated.

Amsinckia intermedia Fisch. & C.A. Mey.
NATIVE
Stem: ascending to erect, green to brown, spreading-bristly, branches 0--many. Leaf: spreading, green, coarse-hairy to bristly. Flower: calyx lobes 5, +- equal, not fused above base; corolla 7--11 mm, tube exserted, tube 10-veined near base, limb 4--10 mm diam, +- orange, generally with 5 dark spots; stamens attached above middle of tube, anthers generally appressed to stigma; style to throat. Fruit: 2--3.5 mm, +- sharp-tubercled, occasionally ridged. Chromosomes: 2n=30,34,38.
Ecology: Open, generally disturbed areas; Elevation: < 1750(2350) m. Bioregional Distribution: CA (uncommon D); Distribution Outside California: to British Columbia, western Montana, Utah, western Texas, Baja California. Flowering Time: Mar--Jun Note: Homostylous. Perhaps better treated as part of Amsinckia menziesii. Hybridizes with Amsinckia lycopsoides, Amsinckia retrorsa; see note under Amsinckia eastwoodiae.
Synonyms: Amsinckia intermedia var. echinata (A. Gray) Wiggins; Amsinckia menziesii (Lehm.) A. Nelson & J.F. Macbr. var. intermedia (Fisch. & C.A. Mey.) Ganders, ined.
Unabridged Note: Self-pollinated. Highly variable, with 100+ named, mostly indistinct variants, some of which may grow together and remain distinct but intergrade over their ranges.
