glands on both sides. R. hallense and
R. hirsutiforme are intermediate forms of a natural cross between R.
hirsutum and R. ferrugincum. They are handsome, small-growing, brightly
flowered plants, and worthy of culture.

R. INDICUM.--Indian Azalea. A native of China (1808), and perfectly
hardy in the more favoured portions of southern England, where it looks
healthy and happy out of doors, and blooms freely from year to year.
This is the evergreen so-called Azalea that is so commonly cultivated in
greenhouses, with long hirsute leaves, and large showy flowers. R.
indicum amoenum (_syn Azalea amoena_), as a greenhouse plant is common
enough, but except in the South of England and Ireland it is not
sufficiently hardy to withstand severe frost. The flowers are, moreover,
not very showy, at least when compared with some of the newer forms,
being dull magenta, and rather lax of habit.

R. LEDIFOLIUM (_syns Azalea ledifolia_ and _A. liliiflora_).--Ledum-leaved
Azalea. China, 1819. A perfectly hardy species. The flowers are large
and white, but somewhat flaunting. It is, however, a desirable species
for massing in quantity, beside clumps of the pink and yellow flowered
kinds. Though introduced nearly three-quarters of a century ago, this
is by no means a common plant in our gardens.

R. MAXIMUM.--American Great Laurel. North America, 1756. This is a very
hardy American species, growing in favoured localities from 10 feet to
15 feet high. Leaves oblong-lanceolate, slightly ferruginous beneath.
Flowers rose and white, in dense clusters. There are several handsome
varieties that vary to a wide extent in the size and colour of flowers.
R. maximum album bears white flowers.

R. MOLLE (_syn Azalea mollis_), from Japan (1867), is a dwarf, deciduous
species of neat growth, with flame-coloured flowers. It is very hardy,
and a desirable acquisition to any collection of small-growing shrubs.

R. OCCIDENTALE (_syn Azalea occidentalis_), Western Azalea, is valuable
in that the flowers are produced later than those of almost any other
species. These are white, blotched with yellow at the base of the upper
petals; and being produced when the leaves are almost fully developed,
have a very pleasing effect, particularly as they are borne in great
quantity, and show well above the foliage. This is a Californian species
that has been found further west of the Rocky Mountains than any other
member of Ihe family.

R. PARVIFOLIUM.--Baiacul, 187
