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; branclilets often hispid. 



1. A. Audersonii, Gr. Erect, 6 or 10 ft. high; branclilets 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 so, mostly 

 Bpinulose-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 tlian 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. pungeus, HBK. Leaves commonly becoming vertical by a twist of the dis-

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



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

 Into one woody stone, half aa inch in diameter. A. hicolor, Gr,, is smaller and has small apparently 

 one-seeded berries. 



4. GAULTHSRIA, 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. Slialion, 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. RHODODSNDRON, 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. oocidsntala, Gr. (Azalea.) A deciduous shrub, 2 to G ft. high; leaves 

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