Hackelia amethystina
AMETHYST STICKSEED

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: HackeliaView DescriptionDichotomous Key

Common Name: STICKSEED
Habit: Perennial herb (biennial); hairs appressed to spreading; caudex generally branched in age, often +- woody, taprooted. Stem: ascending or erect. Leaf: lowest petioles generally +- = blades, +- winged, others 0. Inflorescence: coiled cymes, generally > 3, generally terminal and axillary, +- bracted; pedicel in fruit elongated, recurved to reflexed. Flower: calyx deep-5-lobed; corolla rotate-salverform, generally white with yellow patch adaxially, lobes appendaged near base. Fruit: nutlets erect, > style, attachment scar lateral-medial, generally with barb-tipped prickles abaxially and on margin.
Species In Genus: 40 species: generally western North America, southeastern Asia. Etymology: (J. Hackel, Czech botanist, 1783--1869) Note: Values for corolla limb diam take into account shrinkage during flower period. Difficult, study needed, especially in northern California, southeastern Asia; sometimes merged with Lappula.
Unabridged Note: In North America filling old-world role of flat-flowered forget-me-nots, Myosotis, Lepechiniella, etc, for pollinators.

Hackelia amethystina Eastw.
NATIVE
Stem: 4--8 dm; hairs +- dense, generally +- spreading, generally < 1 mm. Leaf: basal 10--30 cm, 1.3--4 cm wide, narrow-elliptic; lower cauline smaller, generally narrower, ephemeral, hairs +- appressed, soft, generally < 1 mm, occasionally > 1 mm on margins; mid-cauline generally lance-ovate, base truncate to cordate, +- clasping. Inflorescence: open; pedicel 6--9 mm in fruit. Flower: calyx 2--4 mm; corolla tube generally = calyx, throat open, limb 7--12+ mm diam, blue occasionally with pink in center, appendages exserted, longer than wide; anthers at +- middle of tube. Fruit: nutlets 4--5 mm, abaxial prickles generally 10--17, < marginal. Chromosomes: 2n=24.
Ecology: Meadows, forest clearings, roadsides, occasionally along streambanks; Elevation: 1370--2200 m. Bioregional Distribution: NCoRH, n SNH (Plumas, Placer cos.). Flowering Time: Jun--Jul
Unabridged Note: Most common in NCoRH, apparently localized in northern SNH, most notably on Diamond Mountains crest along Plumas-Lassen Co. line. Possibly more common in northern SNH. Most likely mistaken in flower for Hackelia nervosa. Expanded author citation: Hackelia amethystina J.T. Howell ex Eastw.
