AND IS MAINTAINED FOR ARCHIVAL PURPOSES ONLY
Annual, perennial herb, shrubs, generally bristly or sharply hairy
Stem prostrate to erect
Leaves cauline, often with basal rosette, generally simple, alternate; lower sometimes opposite, entire
Inflorescence: cyme, generally elongate, panicle-, raceme- or spike-like, coiled in flower, generally uncoiled in fruit or flowers 12 per axil
Flowers generally bisexual, generally radial; sepals 5, free or fused in lower half; corolla 5-lobed, generally salverform, top of tube generally appendaged, appendages 5, alternating with stamens, sometimes arching over tube; stamens 5, epipetalous; ovary superior, generally 4-lobed, style generally entire
Fruit: nutlets 14, smooth to variously roughened, sometimes prickly or bristled
Genera in family: ± 100 genera, ± 2000 species: tropical, temp, especially w North America, Medit; some cultivated (Borago, Echium, Myosotis, Symphytum ).
Almost all genera may be TOXIC from alkaloids or accumulated nitrates
Recent taxonomic note: Recently treated to include Hydrophyllaceae [Olmsted et al. 2000 Mol Phylog Evol 16:96112]
Family description, key to genera by Timothy C. Messick.
Annual, perennial herb, generally strigose
Stem prostrate to erect, branched at base or above, < 5 dm
Leaves simple, 0.510 cm, generally smaller upward; all cauline (lower opposite, linear to oblong, upper generally alternate) or both basal (often in rosettes) and cauline (alternate, linear to oblanceolate)
Inflorescence: raceme or spike, coiled in bud, generally elongate in fruit; bracts 0many; pedicels generally 01 mm
Flower bisexual; sepals fused below middle, 210 mm in fruit; corolla 112 mm wide, all white or yellow inside tube
Fruit: nutlets generally 4, 13.5 mm; back generally with midrib, lateral ribs, cross-ribs, interspaces, generally tubercled, sometimes prickled or bristled; scar generally lateral (on side) near middle or base, sometimes basal (on bottom) or oblique (between side and bottom), sometimes on a stalk or short peg, generally ovate to triangular
Species in genus: ± 65 species: temp w North America, w South America
Etymology: (Greek: sideways pit, from position of nutlet attachment scar)

Fully mature nutlets critical for identification; intergradation common in some species groups; sect. Allocarya often treated as a separate genus; many species need further study.
Annual, sparsely short-strigose
Stem prostrate to erect, 14 dm
Leaves cauline; lower 37 cm
Inflorescence bracted near base; pedicels conspicuous, generally 210 mm
Flower: calyx ± 4 mm; corolla 510 mm wide
Fruit: nutlet 12 mm, ovoid, dull; cross-ribs irregular to nearly 0; interspaces wider than cross-ribs; scar lateral near base, linear, set in deep groove
Ecology: Grassy and moist places, coastal scrub, chaparral
Elevation: < 100 m.
Bioregional distribution: Central Coast, San Francisco Bay Area.May intergrade with P. undulatus in SnFrB. Varieties intergrade; if differences are environmentally induced, recognition is not warranted.
See the CNPS Inventory for information about endangerment and rarity.
