ERICACEAE. 233 



* * Ovary pubescent; branchlels often hispid. 



5. A. tomentosa (Pursh), Dougl. Erect, 4 — 8 ft. high, tomentose 

 when young, the branohlets and often the petioles hispid with long white 

 rather flaccid-bristly hairs: leaves glaucescent, oblong-lanceolate to 

 ovate and somewhat cordate, entire, or rarely serrulate: fl. in short 

 conspicuously bracted clustered racemes, the pedicels shorter than the 

 bracts : f r. red, puberulent. — Cool slopes of the Coast Bange. 



6. A. Andersonii, Gray. Size of the last, every way similar in 

 aspect, save that the leaves are thinner, longer, and sessile, or nearly so, 

 by a strongly sagittate- clasping base: drupes reddish, much depressed, 

 clothed with short viscid-glandular bristles. — Oakland Hills and south- 

 ward to the Santa Cruz Mts. 



7. A. nuininulai'ia, Gray. Low, more or less spreading, glabrous 

 excepting the bristly hairs of the branchlets: leaves of a vivid light green, 

 not in the least glaucescent, oval, rounded at both ends, or at apex 

 acutish, }/% — % *'". long, shorl-petioled : racemes short and clustered. — 

 Marin Co. and northward. 



4. BROSS-EA, Plumier. Low shrub, with large evergreen leaves, 

 and flowers in axillary racemes from scaly buds. Calyx 5-cleft. Corolla 

 urceolate, 5-toothed. Stamens 10. Fruit closely imitating a berry, but 

 consisting of a depressed 5-celled many-seeded capsule enclosed within 

 the enlarged and fleshy or pulpy calyx. 



1. B. Shallon (Pursh), O. Ktze. Shrubby stems ascending, 1 — 2 ft. 

 high: leaves ovate-cordate, acute or acuminate, 2 — 4 in. long, finely 

 serrate : fl. in terminal and axillary compound viscid glandular racemes : 

 bracts scaly: pedicels 1 — 2-bracteolate below the middle: corolla ovate: 

 fr. blackish and sweet. — Only in the redwood districts, and not very 

 common with us. 



5. RHODODENDRON, Linn. Shrubs with alternate entire leaves, 

 and showy flowers in terminal umbels. Corolla large, with ample limb 

 and, in ours, 5 exserted stamens. Capsule woody, elongated, septicidally 

 5-valved from the summit. Seeds many, small, with a loose testa. 



1. R. occidentale (T. & G.), Gray. Shrub 5—8 ft. high: leaves 

 obovate-oblong or oblanceolate, glabrate, the margins minutely hispid- 

 ciliate: flowers faintly mephitic, appearing after the leaves; corolla 2 in. 

 long or more, minutely viscid-pubescent on the outside, while, with a . 

 long yellow spot on the upper lobe, the narrowly funnelform tube about 

 as long as the limb. —Banks of mountain streams, and on swampy north- 

 ward slopes: plentiful in some parts of Marin Co. 



2. R. Sonomense, Greene. Shrub 2—5 ft. high; leaves somewhat 

 elliptical, 1 in. long or less, the margin serrulate and ciliolate: fl. rose-
