Stem: 4--8 dm; hairs +- dense, generally +- spreading, generally < 1 mm. Leaf: basal 10--30 cm, 1.3--4 cm wide, narrow-elliptic; lower cauline smaller, generally narrower, ephemeral, hairs +- appressed, soft, generally < 1 mm, occasionally > 1 mm on margins; mid-cauline generally lance-ovate, base truncate to cordate, +- clasping. Inflorescence: open; pedicel 6--9 mm in fruit. Flower: calyx 2--4 mm; corolla tube generally = calyx, throat open, limb 7--12+ mm diam, blue occasionally with pink in center, appendages exserted, longer than wide; anthers at +- middle of tube. Fruit: nutlets 4--5 mm, abaxial prickles generally 10--17, < marginal. Chromosomes: 2n=24.
Ecology: Meadows, forest clearings, roadsides, occasionally along streambanks; Elevation: 1370--2200 m. Bioregional Distribution: NCoRH, n SNH (Plumas, Placer cos.). Flowering Time: Jun--Jul
Unabridged Note: Most common in NCoRH, apparently localized in northern SNH, most notably on Diamond Mountains crest along Plumas-Lassen Co. line. Possibly more common in northern SNH. Most likely mistaken in flower for Hackelia nervosa.
