70 ERICACEH. (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 20, mostly 
spinulose-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- 
eal, 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. pumila, Nutt. Erect, dwarf, less than a foot high, tufted; leaves broadest 
near the apex, less than an inch long. 
4, A. pungens, 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 ciliate, 
bearided ; fruit yellowish, turning dull red. Very variable. 
4X, GLAUCA, Lindl., if found, may be recognized by its large fruit, with the seeds consolidated 
‘into one woody stone, half aninch in diameter. .A. bicolor, Gr., 1s smaller and has small apparently 
one-seeded berries. 
“4, GAULTHERIA, L. Wrytercreen. SaLau. 
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. occidentale, Gr. (Azatea.) <A deciduous shrub, 2 to 6 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. OALIFORNICUM, Hook., is a larger evergreen shrub, with large bell-shaped rose-purple flowers: 
a true Rhododendron, probably not found south of Mendocino County.
