Sect. Char. Limb of calyx short, 5-lobed. Corolla funnel-shaped. Sta- 
mens 5. Ovarium 5-celled. Leaves deciduous. This group includes the 
hardy azaleas of the gardens, which have mostly deciduous leaves, and are 
quite distinct in their appearance from the plants of the preceding groups of 
this genus, which are all evergreen and sub-evergreen. After Mr, Don’s name, 
we have given the name previously applied, and then the common English 
name, leaving them to be adopted by the practical gardener, if he should 
think fit. At the same time, those who prefer following Mr. Don have only 
to pass over the names which we have put in parenthesis.

Varieties and Hybrids. There are a great number 
of varieties of this species in the gardens, dif- 
fering principally in the colour of their flowers, 
and the hue of the leaves. The flowers of the 
species are of a fine bright yellow ; but those 
of the varieties are of all shades, from yellow 
to copper, or orange colour; and they are some- 
times of a pure white, or of white striped with yellow and red. _ Besides, 
as this species seeds freely, and is easily cross-fecundated with the North 
American species, an immense number of varieties of it have been crigin- 
ated in British and Continental gardens. The varieties and hybrids which 
are considered as belonging to Azalea pdntica, which are given in Loddiges’s 
Catalogue for 1836, are the following, but new kinds are originated every 
year, and we therefore refer to the yearly catalogues of nurserymen.
