Shrubs, erect or mound-forming, 1–3 m; burl present; twigs tomentose to short-hairy, with eglandular hairs or with long, clear, pink or dark, glandular hairs. Leaves: petiole 5–10 mm; blade bright green, slightly glaucous to strongly gray-glaucous, shiny or dull, elliptic to ovate, 2–4.5 × 1–2.5 cm, base cuneate to rounded, sometimes ± lobed or truncate, margins entire or toothed, plane, surfaces papillate, scabrous or smooth, glabrous or glandular-puberulent to -hairy, puberulent, or finely tomentose, sometimes glabrescent; (abaxial surface sometimes with more stomata than adaxial surface). Inflorescences panicles, 3–6-branched; immature inflorescence pendent, (branches crowded, not concealed by bracts), axis 1–3 cm, 1+ mm diam., short-hairy to hairy, with or without glandular hairs; bracts not appressed, variable, from scalelike and awl-like to leaflike and deltate, lanceolate, or broadly lanceolate (at least at base), 3–10 mm, apex acute, surfaces hairy or finely glandular-hairy. Pedicels 3–10 mm, sparsely hairy to finely glandular-hairy. Flowers: corolla white to pink, conic to urceolate; ovary densely white-hairy, sometimes glandular. Fruits slightly (or markedly) depressed-globose, 6–10 mm diam., glabrous or finely glandular-hairy, (viscid). Stones usually mostly distinct, sometimes connate.
Distribution

Discussion
Subspecies 10 (8 in the flora).
Arctostaphylos glandulosa occurs in the California Floristic Province from southern Oregon to northern Baja California within the Coast, Transverse, and Peninsular ranges.
Selected References
None.
