Amsinckia tessellata


Higher Taxonomy
Family: BoraginaceaeView DescriptionDichotomous Key
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.

Genus: AmsinckiaView DescriptionDichotomous Key


Common Name: FIDDLENECK
Habit: Annual; hairs generally bristly, often bulbous-based. Stem: generally erect, 2--12 dm, generally green. Leaf: basal and cauline, alternate, sessile or lower short-petioled, generally linear to narrow-lanceolate or -oblong, generally not succulent, +- entire. Inflorescence: spike-like cymes, generally +- terminal, tip coiled. Flower: generally radial; calyx lobes 5 or 2--4 (see key); corolla tube generally not constricted, generally orange or yellow (red-orange), appendages generally 0, throat generally open, glabrous, limb on large-flowered taxa generally with 5 dark spots. Fruit: nutlets erect, +- triangular, adaxially generally with exposed elliptic attachment scar, generally with rounded or sharp tubercles.
Etymology: (W. Amsinck, patron of Hamburg Botanic Garden, 1752--1831) Note: Self-compatible; often heterostylous; large-flowered taxa generally cross-pollinated, small-flowered self-pollinated.

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.
