Arctostaphylos glandulosa

Eastwood manzanita, Eastwood's manzanita
Habit 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
