Hackelia micrantha (Eastw.) J.L. Gentry
Stem: generally many from +- stout, woody caudex, 3--11 dm; hairs generally 0 to +- sparse, at mid-stem generally +- spreading, generally > 1 mm. Leaf: basal 6--33 cm, 0.7--3.7 cm wide, narrow-elliptic to oblanceolate, +- green at flower; lower cauline generally 5--23 cm, 0.6--2.4 cm wide, hairs +- appressed, strigose to rough, generally < 1 mm, occasionally > 1 mm on margins; mid to upper cauline generally elliptic, base tapered to obtuse, not +- clasping. Inflorescence: +- wide, +- strigose; pedicel 5--12 mm in fruit. Flower: calyx 1.5--2.7 mm; corolla tube generally = calyx, throat open, limb (4)5--8(11) mm diam, blue, appendages wider than long. Fruit: nutlets 3--5 mm, abaxial prickles generally 4--10, < marginal. Chromosomes: 2n=24.
Ecology: Meadows, streambanks, shrubby slopes, open forest; Elevation: 1200--3500 m. Bioregional Distribution: KR, NCoRH, CaRH, SNH, MP, n SNE (Sweetwater Mtns); Distribution Outside California: western North America. Flowering Time: Jun--Aug
Synonyms: Hackelia jessicae (E.A. McGregor) Brand
Unabridged Note: Most commonly collected Hackelia in California, in widespread, +- expansive populations. CA-FP plants tend to have smaller corollas than those farther northern and e, where other larger-flowered Hackelia species, such as Hackelia nervosa and Hackelia amethystina, are lacking; corolla size does not distinguish from Hackelia floribunda in SN.
