crinite manzanita

brittle leaf manzanita

Habit Shrubs, erect, 1–3 m; burl present; twigs sparsely to densely short-hairy, sometimes glandular or long-hairy.
Twigs

densely short-hairy and with longer, white hairs.

Leaves

blade surfaces densely short-hairy abaxially (and sometimes adaxially).

bifacial in stomatal distribution;

petiole 2–5 mm;

blade dull light green abaxially, shiny dark green adaxially, oblong-ovate to oblong-lanceolate, 2–5 × 1.5–2.5 cm, base truncate to ± lobed, margins entire (sometimes toothed), sometimes cupped or ± revolute, abaxial surface smooth, glabrous or sparsely or finely tomentose, adaxial surface smooth, ± glabrous (sometimes densely tomentose).

Inflorescences

panicles, 2–8-branched;

immature inflorescence pendent, rarely ascending, branches spreading, axis 1–2.5 cm, 1+ mm diam., sparsely to densely short-hairy, sometimes glandular, or long-hairy eglandular;

bracts not appressed, proximal leaflike, distal often scalelike, from scalelike and awl-like to broadly leaflike and deltate to lanceolate, 3–8 mm, apex acute, surfaces glabrous or hairy.

Pedicels

2–5 mm, glabrous or short-hairy.

Flowers

corolla white, conic to urceolate;

ovary white-hairy or glabrous.

Ovaries

densely hairy.

Fruits

depressed-globose, 6–10 mm diam., glabrous or sparsely hairy.

Immature

inflorescence axes glabrous or hairy, sometimes glandular (not densely glandular-hairy).

Stones

distinct.

Discussion

Subspecies crinita occurs in the central and southern Santa Cruz Mountains, and also the interior uplands of Monterey Bay, outer Central Coast Range.

(Discussion copyrighted by Flora of North America; reprinted with permission.)

Subspecies 6 (6 in the flora).

Arctostaphylos crustacea comprises populations from central California and the Channel Islands in areas moderated by summer maritime fog. One subspecies is widespread, from the San Francisco Bay area to the Channel Islands; the others are limited in distribution.
