Photo is of parent taxon

Adams' 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.
Twigs

sparsely short-hairy, not glandular-hairy.

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).

blades strongly white-glaucous, base rounded, sometimes ± lobed to truncate, surfaces smooth, glabrous.

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.

immature inflorescence axis densely white-hairy;

bracts densely white-hairy.

Pedicels

3–10 mm, sparsely hairy to finely glandular-hairy.

densely white-hairy.

Flowers

corolla white to pink, conic to urceolate;

ovary densely white-hairy, sometimes glandular.

Ovaries

densely white-hairy.

Fruits

slightly (or markedly) depressed-globose, 6–10 mm diam., glabrous or finely glandular-hairy, (viscid).

slightly depressed-globose.

Stones

usually mostly distinct, sometimes connate.

distinct.
