Leaf: deciduous or +- persistent, simple, generally cauline, alternate, or proximal opposite and distal alternate, venation pinnate; stipules 0. Inflorescence: cyme, raceme-like, panicle-like, head-like, terminal or axillary, or flowers 1 or paired in axils. Flower: bisexual, radial; calyx lobes 5, fused at base, +- equal, alike in shape, persistent, occasionally enlarged in fruit, sinus appendages 0; corolla deciduous, rotate, funnelform, urceolate, or urceolate-tubular, lobes 5; appendages on tube between filaments 0, appendages at tube top 0, nectary glands 0; stamens 5, epipetalous, included or +- exserted, equal or unequal, filaments equally or unequally attached within corolla tube, filament base sometimes appendaged, or base expanded; ovary generally superior, occasionally half-inferior, chambers 2 or 4, placentas 2, parietal, narrow; styles 2, terminal, branches 2, free to base or fused 3/4 to apex, stigmas generally entire or occasionally lobed; disk subtending ovary generally conspicuous. Fruit: capsule, loculicidal or loculicidal and septicidal; valves 2 or 4. Seed: (1--)2--many; attached fleshy structure 0.
Genera In Family: 3 genera, +- 76 species: Americas, Caribbean, Hawaii; some cultivated (Eriodictyon, Wigandia). Toxicity: Dermatitis sometimes caused by contact with glandular hairs (Eriodictyon parryi, Wigandia). Note: Previously treated within Boraginaceae in TJM2 and APG (1998) or as a tribe (Nameae) or subfamily (Namoideae) within Hydrophyllaceae; a distinct lineage from an emended Hydrophyllaceae (Ferguson 1998[1999]; Refulio-Rodríguez & Olmstead 2014).

Habit: Perennial herb or generally annual, hairy. Leaf: cauline, generally alternate, margin crenate-dentate or generally entire, wavy, flat, or rolled under. Inflorescence: heads or generally clusters, terminal, not coiled, or flowers 1--2 in leaf axils; bracts 0 or generally leaf-like. Flower: calyx generally free from ovary; corolla salverform to bell-shaped, occasionally cylindric; stamens generally attached to corolla at different levels, generally unequal, part fused to corolla generally narrow-winged, scales at base 0; styles 1--2. Fruit: generally loculicidal, ovoid to elliptic. Seed: generally many, small, red-brown, brown, black, or yellow to orange.

Nama rothrockii A. Gray
NATIVE
Habit: Perennial herb, rhizomed, in colonies, generally dense-short-glandular-hairy and long-bristly-nonglandular-hairy, longer hairs generally swollen at base. Stem: erect, 20--30 cm, sticky, branches 0--few. Leaf: 2--6 cm, lanceolate to elliptic, crenate-dentate. Inflorescence: heads; bracts 0; pedicels +- 1 mm. Flower: calyx lobes 8--15 mm, lance-linear; corolla 13--18 mm, +- funnel-shaped, pink, purple, or pale blue, limb 8--10 mm diam, lobes 4--6 mm, 3--6 mm wide; stamens 6--11 mm, attached 4--7 mm above corolla base; styles 2, 7--11 mm. Fruit: 3--6 mm. Seed: 1--2 mm, ovoid, red-brown to brown, minute-pitted. Chromosomes: 2n=34.
Ecology: Sandy alluvial flats, gravelly granitic slopes, meadows; Elevation: 1600--3050 m. Bioregional Distribution: c&s SNH, SnBr, SNE; Distribution Outside California: Nevada, northwestern Arizona. Flowering Time: Jul--Aug Note: Not most closely related to other spp. of Nama based on recent molecular analysis (Vasile et al. 2020 Systematics & Biodiversity 18:757--770), likely warranting a taxonomic change; further work needed.

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.
