Herbs not suffruticose. Stems 10–50(–70) cm, villous and short glandular-puberulent, mixed especially distally, sometimes predominantly glandular puberulent, rarely glabrate. Leaves not fasciculate; blade green to grayish green, usually lanceolate to ovate or broadly elliptical, rarely orbiculate, 0.8–5(–6) × 0.4–1.8(–2.2) cm, margins subentire to distinctly denticulate, 4–10 teeth per side, veins obscure to pronounced, 3–6 per side, surfaces villous and glandular puberulent; bracts sometimes overlapping pedicels of flowers (and fruits). Flowers: floral tube 16–24 mm; sepals 6–9 mm; petals 7–9 mm. Capsules 8–22 mm; subsessile or pedicel 1–2 mm. Seeds 1.2–1.6 × 0.8–1.1 mm. 2n = 30, 60.
Phenology: Flowering Jun–Dec.
Habitat: Sandy or rocky soils in woodland and montane areas, stabilized talus slopes, disturbed ravines, roadsides, granite cliffs, stream banks, stabilized gravel bars.
Elevation: (100–)1000–3200 m.
Distribution
Ariz., Calif., N.Mex., Oreg., Mexico (Baja California, Chihuahua, Sonora).
Discussion
As delimited by J. D. Clausen et al. (1940) and P. H. Raven (1976), subsp. latifolium was considered to be strictly tetraploid. However, at least one population from Arizona (Pima County, Yatskievych s.n. in 1978, MO, count by S. Seavey) was diploid.
Although subsp. latifolium occurs primarily in the Sierra Nevada and Northwestern California subdivisions (B. G. Baldwin et al. 2012) from 1500–3200 m, or in the southern Vancouverian Province as defined by R. F. Thorne (1993d), it is also found at higher elevation in the Pacific Coast Ranges (Central Western and Southwestern California subdivisions). It extends eastward into the Sonoran Province into central and southeastern Arizona, southwestern New Mexico, and Sonora and western Chihuahua, Mexico. In most areas where subsp. latifolium occurs in proximity to subsp. canum, the former occurs at higher elevations.
Selected References
