TREES AND SHRUBS 



CLAMMY AZALEA, Rhododendron viscosum. 



Gardens, shrubberies. Julj' — August. This is the latest flowering of the 

 deciduous Azaleas, one of the hardiest, most floriferous, and easily managed. It 

 is best in rather moist peat. 



Floivers white, sometimes pink, fragrant, appearing after leaves, in a 

 terminal niiibelhtte cluster; pedicels glandular ; Calyx small; Corolla l|-2 ins. 

 long, viscid, tube densely glandular, longer than lobes, limb 1-2 ins. broad, 

 2-lipped ; Fruit a capsule, glandular-bristly, h in. long. 



Leaves oblong-ovate, entire, acute, or obtuse, ciliated, glabrous, green 

 both surfaces, midrib bristly, 2-4 ins. long. 



A deciduous shrub, 2-4 ft. ; shoots bristly. 



Introduced from N. America by Peter Collinson, 1734. Known in U.S.A. 

 as Swamp Honeysuckle. Syn. Azalea xiscosa. 



CALIFORNIAN RHODODENDRON, Rhododendron californicum. 



Gardens, shrubberies. June. Rhododendrons are better for a mulch of 

 well-decayed manure in INIay ; even decayed leaves or grass cuttings are 

 beneficial if covered with soil. All seed-pods should be removed directly 

 the flowers fade. The species are propagated by cuttings of firm shoots, 3 

 ins. long, in sandy peat under bell-glass in temperature of 45°-55', ultimately 

 raising this to G5° ; layering in September or March ; grafting on common 

 species in close frame in JNIarch ; seeds sown on the surface of finely prepared 

 sandy peat under bell-glass in cold frame. 



Floivers rose-purple, 2^-3 ins. diam., in a terminal umbel ; Calyx 

 gamosepalous, 5-toothed, small, slightly pilose; Corolla broadly campanulate, 

 5-lobed, upper petal spotted greenish-yellow, tube very short ; Stamens 10, 

 shorter than corolla; Fruit a capsule, woody. 



Leaves alternate, obovate-elliptical, entire, acute, coriaceous, glabrous, 

 shortly petiolate, dark-green, paler beneath. 



An evergreen shrub, 6-8 ft. 



Native of California.
