70 ERICACE^:. (HEATH FAMILY.) 



to 10 bony seeds. The white or rose-colored flowers in terminal racemes; the bark smooth, 



exfoliating. 



* Ovary and depressed-globose fruit more or less pubescent; branchlets often hispid. 



1. A. Andersonii, Gr. Erect, 6 or 10 ft. high; branchlets minutely tomentose, 

 hispid with long, white, bristly hairs; leaves thin-coriaceous, green, lanceolate-oblong or 

 ovate lanceolate, with a strongly sagittate-cordate base, sessile or nearly eo, mostly 

 epinulose-serrulate; fruit nearly or quite half an inch in diameter, with viscid bristles. 



2. A. tomentosa, Dougl. Leaves thick and very rigid -coriaceous, varying from oblong- 

 lanceolate to ovate and even cordate, entire or rarely serrulate, usually becoming verti- 

 cal, smaller than the last; flowers in very short clustered racemes; fruit not viscid. 



* * Ovary glabrous; no hispid hairs on the branches and petioles. 



3. A. punnla, Nutt. Erect, dwarf, less than a foot high, tufted; leaves broadest 

 near the apex, less than an inch long. 



4. A. puugens, HBK. Leaves commonly becoming vertical by a twist of the dis- 

 tinct or pretty long petiole, very rigid, often glaucous or pale, entire or with a few teeth, 

 varying from oblong-lanceolate to oval; flowers on smooth pedicels; filaments ciiiate, 

 bearded; fruit yellowish, turning dull red. Very variable. 



A. GLAUCA, Lindl., if found, may be recognized by its large fruit, -with the seeds consolidated 

 into one woody stone, half an inch in diameter. A. bicolor, Gr., is smaller and has small apparently 

 one-seeded berries. 



4. GAULTHBRIA, L. WINTERGREEN. SALAL. 



Calyx 5- cleft, generally colored like the corolla. Corolla 5-toothed. Stamens 10 

 included, similar to those of Arbutus. Capsule 5-lobed, 5-celled, many-seeded, inclosed 

 in the calyx, which enlarges and makes a juicy berry -like fruit. 



1. G. Shallon, Pursh. Shrubby, stems ascending a foot or two in height; leaves 

 ovate or slightly cordate, 2 to 4 inches long, finely serrate, shining; flowers white or rose- 

 colored, in glandular-viscid racemes. 



5. RHODODENDRON, L. 



Calyx very small. Corolla often slightly irregular. Stamens 5 to 10; filaments fili- 

 form. Style long, commonly declined or incurved. Shrubs with alternate, entire leaves, 

 usually crowded on the flowering branchlets; the showy flowers in. terminal umbels or 

 corymbs from ample scaly buds. 



1. R. oocidentale, Gr. (AZALEA.) A deciduous shrub, 2 to C ft. high; leaves 

 obovate-oblong, bright green and shining above; corolla minutely viscid-pubescent out- 

 side, white, the upper lobe yellowish inside; the narrow funnel-form tube equaling the 

 deeply 5-cleft slightly irregular limb; stamens and style much exserted, curved. The 

 showy fragrant flowers are sometimes nearly three inches long; rarely pinkish. 



R. CALIFOENICUM, Hook., is a larger evergreen shrub, with large bell-shaped rose-purple flowers 1 

 a true Rhododendron, probably no* found south of Mendocino County.
