Eriodictyon parryi

Higher Taxonomy
Family: BoraginaceaeView DescriptionDichotomous Key
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: Subshrub, dense-glandular, sticky, strong-scented. Stem: erect, 1--3 m, stout, branched from, generally woody at base. Leaf: dense, sessile; blade 4--30 cm, lanceolate, entire or toothed, margins of upper occasionally rolled under. Inflorescence: terminal, branched; flowers dense-clustered, short-pedicelled. Flower: calyx lobes 3--6 mm, glandular, coarse-long-hairy; corolla 10--20 mm, shallow-lobed, funnel-shaped, blue, lavender, or purple, glandular, hairy abaxially; stamens included, unequal; ovary chambers appearing 2, style 4--7 mm.

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.
