BORAGINACEAE BORAGE or WATERLEAF FAMILY

Ronald B. Kelley, Robert Patterson, Richard R. Halse & Timothy C. Messick, family description, key to genera; treatment of genera by Ronald B. Kelley, except as noted

Annual to shrub, 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, appendages 0 or 5 at top of tube, alternate stamens; stamens epipetalous; ovary 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.
± 120 genera, ± 2300 species: tropics, temperate, especially western North America, Mediterranean; some cultivated (Borago, Heliotropium, Echium, Myosotis, Nemophila, Phacelia, Symphytum). Many genera may be TOXIC from pyrrolizidine alkaloids or accumulated nitrates. [Olmstead et al. 2000 Molec Phylogen Evol 16:96–112] Recently treated to include Hydrophyllaceae, Lennoaceae. —Scientific Editors: Ronald B. Kelley, Robert Patterson, Thomas J. Rosatti, Bruce G. Baldwin, David J. Keil.

CRYPTANTHA

Ronald B. Kelley, Michael G. Simpson & Kristen E. Hasenstab-Lehman

Annual to perennial herb, generally erect. Stem: branches 0 or generally ascending to erect, hairy. Leaf: generally sessile; basal whorled, cauline generally alternate, reduced above (opposite below); generally strigose, rough-hairy, or bristly, largest bristles generally bulbous-based. Inflorescence: generally terminal, raceme- or generally spike-like cymes, in groups of 1–5 (> 5), generally coiled in bud, generally elongated in fruit; bracts generally 0. Flower: generally unscented, persistent or not; sepals fused at base; corolla tube generally 1–13 mm, limb 0.5–12 mm diam, generally white, appendages generally 5; anthers included; ovary generally 4-lobed. Fruit: pedicel 0 or < 12 mm in fruit; nutlets 1–4, generally gray to brown, smooth to granular, tubercled, or papillate, with abaxial, longitudinal ridge to not; margin rounded, sharp-edged, or a ± flat rim or wing; adaxially grooved above attachment scar, scar generally lateral, narrow, open to closed, raised or generally not, edges inrolled to sharp-angled, generally forked or flared open at base; central fruit axis ("axis") not reaching to extending beyond fruit.
± 200 species: western North America, western South America, northeastern Asia (1 sp.). (Greek: hidden flowers, from cleistogamous flowers of some South American species) Generally homostylous. The tissue between ovary lobes, interpreted as a receptacle and/or style (style sometimes 0, then stigma attached to top of receptacle), extends to various degrees in fruit, forming what is often called the gynobase (here "fruit axis"), to which the nutlets are laterally attached at maturity, leaving an attachment scar. Annual species without yellow corolla appendages generally self-pollinating; perennial herb species generally homostylous in California. Some species, e.g., Cryptantha angustifolia, Cryptantha ambigua, Cryptantha barbigera, Cryptantha mariposae, hybridize with co-occurring species. Observation of nutlets, hairs best at 10+× generally critical for identification. Corolla limb diam generally < at end of flower period, especially for annual species Cryptantha sobolifera Payson does not occur in California.

C. costata Brandegee RIBBED CRYPTANTHA
NATIVE
Annual 10–20 cm, coarse; root often red-purple. Stem: branches few, stiff; dense-strigose and sparse-spreading-bristly. Leaf: 1–3(4) cm, linear to lanceolate, ± folded along midvein, drying long-acuminate or awl-shaped, dense-strigose and rough-hairy to sparse-spreading-bristly, hairs bulbous-based. Inflorescence: in 1s or 2s, dense; bracts ± scattered, spreading-bristly, deciduous; pedicel 0–0.5 mm, stiff-spreading. Flower: calyx 2.5–4 mm, 4–6 mm in fruit, generally constricted above, persistent, lobes lance-linear, tips ± spreading, strigose on margins, midvein thickened, especially in age, dense-long-bristly; corolla limb 1–2(2.5) mm diam, appendages minute, pale yellow. Fruit: nutlets (3)4, 1.2–1.8(2) mm (1 ± > others), triangular or oblong-ovate, brown, shiny, margin occasionally sharp-angled or generally ± flat narrow rim, base wide-truncate; abaxially strongly convex, dome-like, minute-rippled, sparse-grainy to obscurely tubercled, ridge 0; adaxially smooth, flat to ± concave, attachment scar edges not raised, abutted near tip, gapped below, triangular-flare-gapped at base; axis beyond nutlets.
Fine sand deposits (coarser soils), creosote-bush scrub; < 600(1000) m. e Mojave Desert, Sonoran Desert; southern Nevada, Arizona, Baja California. Jan–May [Online Interchange] {CNPS list}
