18. Arctostaphylos glauca Lindley, Edwards's Bot. Reg. 21: sub plate 1791. 1835.

Bigberry manzanita

Arctostaphylos glauca var. puberula J. T. Howell

Shrubs or trees, erect, mound-forming, 1-8 m; burl absent; twigs usually glabrous, some-times short-hairy or glandular-hairy. Leaves: petiole 7-15 mm; blade white-glaucous, dull, oblong-ovate to ± orbiculate, 2.5-5 × 2-4 cm, base rounded, truncate, or slightly lobed, margins entire, plane, surfaces smooth, glabrous. Inflorescences panicles, 4-8-branched; immature inflorescence pendent, branches spreading, axis 2-3 cm, 1+ mm diam., usually glabrous, sometimes short-hairy or glandular-hairy; bracts not appressed, (spreading), scalelike, deltate, 3-6 mm, (fleshy), apex mucronate, surfaces glabrous; (buds exposed). Pedicels 8-10 mm, finely glandular-hairy. Flowers: corolla white, conic to urceolate; ovary densely glandular-viscid. Fruits globose, 12-15 mm diam., glabrous, (viscid). Stones connate into single sphere. 2 n = 26.

Flowering winter-early spring. Rocky slopes, chaparral, woodlands; 300-2200 m; Calif.; Mexico (Baja California).

Arctostaphylos glauca is widespread, occurring from Mount Diablo in central California through the southern Coast Ranges, east through the Transverse Ranges into the desert, and south in the Peninsular Ranges into northern Baja California, usually in drier interior ranges. It is distinctive throughout its range; however, some populations have nonglandular twig puberulence and others are stipitate-glandular, often mixed in with individuals that are typically glabrous. Arctostaphylos glauca can be a component of chaparral and can also be found in woodlands and at the edges of grasslands.
