Hackelia velutina (Piper) I.M. Johnst.
Stem: 4--8 dm; hairs generally spreading, +- dense below middle, +- dense to +- sparse above. Leaf: velvety-hairy; basal generally 5--17 cm, 0.5--2 cm wide, narrow-elliptic to oblanceolate; lower cauline reduced, ovate to narrow-lanceolate, +- clasping upward. Inflorescence: +- dense, branches several, few-flowered; pedicel 6--20 mm in fruit. Flower: calyx 2--3 mm; corolla tube generally >> calyx, generally +- purple, throat +- closed, limb 12--20 mm diam, generally blue to +- purple (pink), appendages long-exserted, much longer than wide, recurved, 2-pronged at tip, white; anthers hidden. Fruit: nutlets 4.5--6.5 mm, dull, roughened, abaxial prickles many, evenly distributed, +- = marginal.
Ecology: Dry, open slopes, forest clearings, roadsides; Elevation: 1350--2750 m. Bioregional Distribution: SNH; Distribution Outside California: western Nevada. Flowering Time: Jun--Aug
Synonyms: Hackelia longituba I.M. Johnst.
Unabridged Note: Though corolla distinctive, mistaken for Hackelia nervosa, Hackelia mundula: the unique long-exserted recurved corolla appendages and overall velvety hairs distinguish it from Hackelia nervosa; the exserted corolla tube, white corolla appendages, and dull, roughened nutlets separate it from Hackelia mundula. A CalPhoto image taken in southern SN shows a pink flowered pl, no doubt indicating introgression with Hackelia mundula. The suspected occurrence of Hackelia velutina in CaRH based on multiple CalPhoto images in the Lassen Volcanic National Park area, though it is uncertain whether voucher specimens exist.
