in diameter, and arranged
in rather straggling terminal heads. They are sulphur-yellow, without
markings, a tint distinct from any other known Indian species.

R. CATAWBIENSE.--Mountains from Virginia to Georgia, 1809. A bushy, free
growing species, with broadly oval leaves, and large campanulate
flowers, produced in compact, rounded clusters. They vary a good deal in
colour, but lilac-purple is the typical shade. This is a very valuable
species, and one that has given rise to a large number of beautiful
varieties.

R. CHRYSANTHUM is a Siberian species (1796) of very dwarf, compact
growth, with linear-lanceolate leaves that are ferruginous on the under
side, and beautiful golden-yellow flowers an inch in diameter. It is a
desirable but scarce species.

R. COLLETTIANUM is an Afghanistan species, and one that may be reckoned
upon as being perfectly hardy. It is of very dwarf habit, and bears an
abundance of small white and faintly fragrant flowers. For planting on
rockwork it is a valuable species.

R. DAHURICUM.--Dahuria, 1780. A small-growing, scraggy-looking species
of about a yard high, with oval-oblong leaves that are rusty-tomentose
on the under sides. The flowers, which are produced in February, are
purple or violet, in twos or threes, and usually appear before the
leaves. It is a sparsely-leaved species, and of greatest value on
account of the flowers being produced so early in the season. One of the
hardiest species in cultivation. R. dahuricum atro-virens is a beautiful
and worthy variety because nearly evergreen.

R. FERRUGINEUM.--Alpine Rose. Europe, 1752. This dwarf species, rarely
exceeding a yard in height, occurs in abundance on the Swiss Alps, and
generally where few other plants are to be found. It is a neat little
compact shrub, with oblong-lanceolate leaves that are rusty-scaly on the
under sides, and has terminal clusters of rosy-red flowers.

R. FLAVUM (_syn Azalea pontica_).--Pontic Azalea. A native of Asia Minor
(1793), is probably the commonest of the recognised species, and may
frequently, in this country, be seen forming good round bushes of 6 feet
in height, with hairy lanceolate leaves, and large yellow flowers,
though in this latter it varies considerably, orange, and orange tinged
with red, being colours often present. It is of free growth in any good
light peaty or sandy soil.

R. HIRSUTUM.--Alpine Rose. South Europe, 1656. Very near R. ferrugincum,
but having ciliated leaves, with
