STREAMSIDE BLUEBELL


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.

Habit: Perennial herb, generally from taprooted, branched caudex; glabrous to spreading-hairy. Stem: +- erect. Leaf: cauline and generally basal, alternate, generally petioled, upper generally sessile. Inflorescence: generally panicle- or raceme-like cymes; bracts 0. Flower: calyx generally deep-lobed; corolla often +- cylindric or bell-shaped, blue, generally pink in bud, tube generally well developed, exceeding calyx, abruptly expanded at throat, with or without ring of inner hairs, appendages present or not; filaments often +- flat, generally attached +- below appendages, anthers included. Fruit: nutlets generally wrinkled, attached near or below middle.
Species In Genus: +- 50 species: North America, temperate Eurasia. Etymology: (F.C. Mertens, German botanist, plant collector, 1764--1831) Note: Hybrids common; identification sometimes difficult, especially in MP.

Mertensia ciliata (Torr.) G. Don var. stomatechoides (Kellogg) Jeps.
NATIVE
Habit: Plant 4--15 dm from thick branched thick-taprooted caudex, glabrous, occasionally glaucous. Stem: clustered, leafy. Leaf: basal generally > cauline; cauline with conspicuous lateral veins, lower petioled; blades lanceolate to ovate, acute. Inflorescence: panicle-like, open. Flower: calyx 1.5--4 mm; corolla 10--17 mm, limb generally 0.8--1.2(1.5) × tube, tube > calyx, generally without with ring of hairs inside, appendaged; filaments wide, generally > anthers; style exserted 2--5 mm. Chromosomes: 2n=24,48.
Ecology: Streamsides, wet meadows, damp thickets, wet cliffs; Elevation: 1310--3380 m. Bioregional Distribution: s CaRH, SNH, MP, W&I; Distribution Outside California: to western Nevada. Flowering Time: Jun--Aug
Unabridged Note: Mertensia ciliata var. ciliata (calyx 1--3 mm, style exserted 1--3 mm) western United States except California. Plants in CaRH, MP need study.

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.
