Cryptantha juniperensis

Higher Taxonomy
Family: BoraginaceaeView DescriptionDichotomous Key

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.

Cryptantha juniperensis R.B. Kelley & M.G. Simpson
Habit: Plant 5--35 cm, narrow, grayish. Stem: branches generally erect, +- short and stiff, generally sparsely spreading-rough-hairy to soft-bristly, especially near base. Leaf: 0.5--3.5 cm, linear to oblanceolate, densely appressed-fine-hairy, margins occ spreading-rough-hairy. Inflorescence: cymes generally in 2s; bracts 0; pedicel < 0.5 mm. Flower: calyx 1.5--3 mm, 4.5--7.5 mm and ascending in fruit, late-deciduous, lance-ovoid to occasionally urn-shaped, +- constricted above,, lobes lanceolate, tips erect to slightly recurved, margin sparsely strigose, midrib thickened, ascending to spreading soft-bristly, longest bristles near base; corolla limb late deciduous, 2--5 mm diam., appendages pale yellow. Fruit: (1.6--)1.7--2.1(--2.5) mm, lance-ovate to narrowly ovate, not flattened, densely papillate and coarsely tubercled, dull to glossy, margin rounded to sharp-angled, base rounded, tip tapered; abaxially rounded, ridge 0; adaxially flat to low-rounded, attachment scar edges generally not raised, abutted to gapped entire length, flare-gapped at base, style extended +- = nutlet length.
Ecology: Sandy, silty, loamy, to gravelly soils, generally open slopes, often California juniper woodland, foothill woodland, pinyon/juniper woodland, open chaparral, sparse grasslands; Elevation: 80--2380 m. Bioregional Distribution: s SN, Teh, w SnJV, CW (exc CCo), TR, SnJt, w DMoj, DMtns (New York Mtns); Distribution Outside California: to southern Utah, New Mexico, Baja California. Flowering Time: Mar--Jul Note: Recently elevated to species status (see Simpson & Kelley 2017); widespread, though often overlooked and mis-identified, and apparently ecologically affiliated with the historic range of California juniper woodland in central and southern California. Differs from C. nevadensis in stem habit, inflorescence development, calyx length, corolla limb diameter, and nutlet shape.
Synonyms: Cryptantha nevadensis var. rigida I.M. Johnst.; Cryptantha intermedia var. rigida (Brand) Jeps. & Hoover

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.
