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: BLUEBELL 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. Etymology: (F.C. Mertens, German botanist, plant collector, 1764--1831) Note: Hybrids common; identification sometimes difficult, especially in MP. eFlora Treatment Author: Ronald B.

Mertensia longiflora Greene
NATIVE Habit: Plant generally < 4 dm from tuber-like root, glabrous to +- strigose. Stem: generally 1--2, easily detached. Leaf: basal rare on flowering plants; cauline few, generally sessile, generally 1.5--4 × longer than wide, lateral veins obscure. Inflorescence: +- panicle-like, dense. Flower: calyx 3--6 mm; corolla 15--25 mm, limb 0.3--0.5(0.6) × tube, tube >> calyx, glabrous inside, appendaged; filaments wide, > anthers; style +- included. Ecology: Open, generally spring-moist, drying places of plains, foothills, especially with sagebrush or sparse ponderosa-pine forest; Elevation: 1500--2200 m. Bioregional Distribution: MP; Distribution Outside California: to British Columbia, Montana. Flowering Time: Apr--Jun Jepson eFlora Author: Ronald B.

(Note: any qualifiers in the taxon distribution description, such as 'northern', 'southern', 'adjacent' etc., are not reflected in the map above, and in some cases indication of a taxon in a subdivision is based on a single collection or author-verified occurrence).
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.
