Al-Shehbaz & M. S. Mayer

Novon 18: 280. 2008.

Treatment appears in FNA Volume 7. Treatment on page 713. Mentioned on page 712, 714.

Stems moderately hirsute proximally, glabrous distally, 1.7–3.8 dm. Cauline leaves: blade flat distally, margins dentate, surfaces sparsely hirsute. Racemes secund; rachis straight. Fruiting pedicels 5–10 mm, glabrous or sparsely pubescent. Flowers: sepals white or cream, 3–5 mm, glabrous or sparsely pubescent; petals white (with purple veins), 7–8 mm; adaxial filaments 5–6 mm. Fruits divaricate-ascending, straight or curved inwards; valves glabrous or sparsely pubescent.


Phenology: Flowering Jun–Jul.
Habitat: Serpentine areas

Discussion

Of conservation concern.

Subspecies josephinensis, known from Josephine County, is disjunct from the white-flowered Californian subspecies. R. C. Rollins (1993) and R. E. Buck et al. (1993) attributed the Oregonian plants to subspp. glandulosus and secundus, respectively.
