254 Leriacce— Rhododendron. 
inches deep, with a spreading limb resembling those of Liliwm 
cindidum. To this list might be added many more from the 
same region; but we content ourselves with naming one more, 
the Rh. Blandfordiaflorwm, remarkable for its tubular pen- 
dulous cinnabar and orange flowers. We must not forget to 
mention that several hardy Japanese species have recently been 
introduced: Rh. Fortinet and Rh. Metternichit, with oblong 
or obovate coriaceous leaves rusty-tomentose beneath, and 
corymbose heads of campanulate rose-coloured flowers. 
Notwithstanding the great diversity and beauty of the wild 
forms of this genus, many horticulturists—notably in England 
—-have crossed them, and thus obtained many new and distinct 
varieties, usually termed hybrids. For detailed descriptions of 
these we must refer our readers to the nursery catalogues of 
the principal growers. 
Rhodothamnus Chamecistus is a handsome alpine shrub 
from Switzerland, having oval serrate ciliate leaves and solitary 
rosy flowers. It is separated from Rhododéndron on account 
of its rotate corolla and spreading stamens. 
Rhodora Canadénsis, syn. Rhododéndron Rhodora, is a de- 
ciduous shrub often seen in gardens, with purple sweet-scented 
flowers appearing before the leaves in Spring. 
8. AZALEA. 
Deciduous or evergreen shrubs. Leaves membranous, often 
ciliate and hairy, mucronate. Flowers large and showy, often 
glandular and clammy, expanding before the new leaves are 
fully developed. Corolla funnel-shaped. Stamens exserted, 
usually 5, filaments long. Botanists now unite this with 
Rhododéndron in consequence of the discovery of species 
intermediate in character; but it will be more convenient to 
keep the hardy species separate in this work, because they are 
so universally known under these distinctive names. The 
species referred here are not. so numerous, but the genus has 
much the same range. The name is from afadéos, parched, 
in allusion to the natural habitats of some species. 
Leaves Deciduous. 
1. A. Poéutica.—This species is a native of Asia Minor, and 
ordinarily grows from 3 to 6 feet high, with lanceolate soft 
hairy leaves and yellow or orange flowers sometimes tinged 
with red.
