348 RHODODENDRON 



R. CAMPYLOCARPUM, Hooker fit. 

 (Bot. Mzig., t. 4968.) 



An evergreen shrub, 4 to 8 ft. high, of neat, bushy habit. Leaves i\ to 

 4 ins. long, half as wide ; heart-shaped or rounded at the base, the apex with 

 a short, abrupt tip ; upper surface dark glossy green, lower one vividly blue- 

 white ; stalk ^ to i in. long, thickly set with stalked glands when young. 

 Flowers pale yellow, slightly fragrant, in loose terminal clusters of six to 

 eight ; corolla bell-shaped, 2^ to 3 ins. across ; lobes five, rounded ; calyx 

 scarcely |- in. across, the five shallow lobes edged with dark, stalked, viscid 

 glands ; flower-stalk about I in. long, and, like the ovary and base of style, 

 glandular ; stamens ten, downy at the base. 



Native of the Sikkim Himalaya at 12,000 ft. Although not one of the 

 hardiest species, it has lived outside in the sheltered Rhododendron Dell at 

 Kew for over twenty years with no other protection than the situation affords. 

 It is at present the best of the larger species with yellow flowers (apart from 

 .Azalea) in cultivation, although the colour, in some forms especially, is too 

 pale and sulphur-like to give hopes of founding upon it a race of golden- 

 flowered kinds. Perhaps the finest example of this rhododendron is in the 

 Earl of Morley's garden at Whiteway, in Devonshire, which some years ago 

 was 8 ft. high. 



R. CANESCENS, G. Don. MOUNTAIN AZALEA. 



(Azalea canescens, Michaux.") 



A deciduous shrub up to 10 ft. high, nearly allied (and joined by inter- 

 mediate forms) to R. nudiflorum, from which it differs in having the leaves 

 grey-downy on the midrib and veins beneath, especially when young (not bristly 

 on the midrib, as in R. nudiflorum) ; in the corolla-tube, flower-stalk, and 

 seed-vessel being glandular, and in the five stamens not being so much pro 

 truded. -Flowers pink or rose-coloured, fragrant, borne on the naked shoots. 



Native of Eastern N. America ; introduced in 1810, according to Loudon, 

 but much confused with nudiflorum, and to some extent with calendulaceum. 

 The latter it resembles in the downy under-surface of the leaf, but is quite 

 different in the colour of the flower. 



R. CATAWBIENSE, Michaux. 

 (Bot. Mag., t. 1671.) 



An evergreen shrub, 6 to 10 ft. high, forming eventually a large spreading 

 bush wider than high a dense thicket of branches and leaves. Leaves oval 

 or oblong, 3 to 6 ins. long, \\ to 2 ins. wide ; broadest above 'the middle, 

 dark glossy green above, pale beneath, smooth on both sides ; stalk \ to \\ 

 ins. long. Flowers lilac-purple, produced in a large cluster 5 or 6 ins. across ; 

 corolla \\ ins. long, 2^ ins. broad, with five short, rounded spreading lobes ; 

 calyx with five shallow, itriangular pointed lobes ; stamens white, downy at 

 the base ; flower- stalks I to i-^ ins. long, glandular-downy ; ovary brown- 

 felted! 



Native of the slopes and mountain summits of the south-eastern United 

 States, where it is described as forming dense thickets "through which the 

 traveller can only make his way by following old bear tracks." In the gardens 

 of Britain, to which it was introduced in 1809 by John Fraser, it has proved 

 perhaps the most valuable evergreen shrub for ornament ever introduced. In 

 the hands of nurserymen, but chiefly of the Waterers, it has given birth by
