Common Name: BORAGE FAMILY Habit: Annual, perennial herb, or shrub, often bristly or sharp-hairy. Stem: prostrate-decumbent to erect. Leaf: basal and/or cauline, simple, generally alternate, sometimes opposite, especially at base. Inflorescence: cymes, arranged singly or in groups of 2--5, generally coiled in flower, generally elongating in fruit. Flower: bisexual, generally radial; sepals 5, free or fused at least at base; corolla 5-lobed, salverform, funnel-shaped, rotate, or bell-shaped, appendages (often called "fornices") 0 or 5 at top of tube, when present often differentially pigmented, alternate stamens; stamens epipetalous; ovary superior, 4-lobed, style 1, entire or minutely 2-lobed (2-branched). Fruit: nutlets 1--4, when > 1, all similar (often called "homomorphic") or 1 or 2 dissimilar in size and/or shape from the others (often called "heteromorphic"), free (fused), smooth to roughened, prickly or bristly or not. Genera In Family: +- 90 genera, +- 1600--1700 species: mostly temperate, especially western North America, Mediterranean; some cultivated (Borago, Echium, Myosotis, Symphytum). Toxicity: Many genera may be TOXIC from pyrrolizidine alkaloids or accumulated nitrates. Note: Sometimes still treated in broader sense of TJM2 (e.g., APG IV 2016 Bot J Linn Soc 181:1--20), but recent evidence (Luebert et al. 2016) supports segregation, for our flora, of the families Ehretiaceae, Heliotropiaceae, Hydrophyllaceae, Lennoaceae, and Namaceae. eFlora Treatment Author: Michael G.

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. 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. eFlora Treatment Author: Ronald B. Kelley & Robert L.

Hackelia micrantha (Eastw.) J.L. Gentry
NATIVE Stem: generally many from +- stout, woody caudex, 3--11 dm; hairs generally 0 to +- sparse, at mid-stem generally +- spreading, generally > 1 mm. Leaf: basal 6--33 cm, 0.7--3.7 cm wide, narrow-elliptic to oblanceolate, +- green at flower; lower cauline generally 5--23 cm, 0.6--2.4 cm wide, hairs +- appressed, strigose to rough, generally < 1 mm, occasionally > 1 mm on margins; mid to upper cauline generally elliptic, base tapered to obtuse, not +- clasping. Inflorescence: +- wide, +- strigose; pedicel 5--12 mm in fruit. Flower: calyx 1.5--2.7 mm; corolla tube generally = calyx, throat open, limb (4)5--8(11) mm diam, blue, appendages wider than long. Fruit: nutlets 3--5 mm, abaxial prickles generally 4--10, < marginal. Chromosomes: 2n=24. Ecology: Meadows, streambanks, shrubby slopes, open forest; Elevation: 1200--3500 m. Bioregional Distribution: KR, NCoRH, CaRH, SNH, MP, n SNE (Sweetwater Mtns); Distribution Outside California: western North America. Flowering Time: Jun--Aug Synonyms: Hackelia jessicae (E.A. McGregor) Brand Unabridged Note: Most commonly collected Hackelia in California, in widespread, +- expansive populations. CA-FP plants tend to have smaller corollas than those farther northern and e, where other larger-flowered Hackelia species, such as Hackelia nervosa and Hackelia amethystina, are lacking; corolla size does not distinguish from Hackelia floribunda in SN.

MAP LEGEND View all CCH records All markers link to CCH specimen records. The original determination is shown in the popup window.
Blue markers indicate specimens that map to one of the expected Jepson geographic subdivisions (see left map). Purple markers indicate specimens collected from a garden, greenhouse, or other non-wild location.
Yellow markers indicate records that may provide evidence for eFlora range revision or may have georeferencing or identification issues.
