BORAGINACEAE

BORAGE FAMILY

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 1–2 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 1–4, 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 16:96–112]

AMSINCKIA

FIDDLENECK

Fred R. Ganders

Annual; hairs generally bristly, often with bulbous bases
Stem generally erect, 2–12 dm, generally green
Leaves basal and cauline, alternate, sessile or lower short-petioled, generally linear to narrowly lanceolate or oblong, generally ± entire
Inflorescence spike-like, generally ± terminal; tip coiled
Flower generally radial; calyx lobes 5, sometimes appearing to be 2–4 from fusion; corolla orange or yellow, limb generally with 5 red-orange marks
Fruit: nutlets erect, ± triangular, generally with oval lateral scar, generally with round or sharp tubercles
Species in genus: 10 species: w North America, sw South America, widely alien elsewhere
Etymology: (W. Amsinck, patron of Hamburg Botanic Garden, early 19th century)
Reference: [Ray & Chisaki 1957 Amer J Bot 44:529–554]
Self-compatible; often heterostylous; large-flowered taxa generally cross-pollinated, small-flowered self-pollinated. Seeds and herbage TOXIC to livestock (especially cattle) from alkaloids and high nitrate concentrations. Sharp plant hairs irritate human skin.

YOU CAN HELP US make sure that our distributional information is correct and current. If you know that a plant occurs in a wild, reproducing state in a Jepson bioregion NOT highlighted on the map, please contact us with that information. Please realize that we cannot incorporate range extensions without access to a voucher specimen, which should (ultimately) be deposited in an herbarium. You can send the pressed, dried collection (with complete locality information indicated) to us (e-mail us for details) or refer us to an accessioned herbarium specimen. Non-occurrence of a plant in an indicated area is difficult to document, but we will especially value your input on those types of possible errors (see automatic conversion of distribution data to maps).
