species was introduced by Sir Joseph Banks in 1793, and it soon became very common, from its being of very easy 
culture, and readily multiplied by cuttings. Under favourable circumstances it flowers twice in the year; that is, 
in early spring, and again in autumn. It is very nearly hardy.

Description, &c.—This very handsome species is a native of Kangaroo Island, on the south coast of New 
Holland. It is a very ornamental plant, with bright salmon-coloured flowers, which it produces in very great 
abundance. It was introduced in the year 1824, and is a remarkably healthy, free-growing plant, striking readily 
from cuttings.

Description, &c.—This very showy species, which is now one of our commonest greenhouse plants, was intro- 
duced in 1806. It is a remarkably free-growing plant, particularly if planted in the ground in a conservatory, 
where it forms a shrub six feet high, which is covered with flowers during the months of March and April. The 
flowers are remarkably showy, being of a deep crimson, tipped with green; but they are totally without fragrance. 
The soil which suits the plant best is a mixture of hazel loam and peat earth; and the species is propagated by 
cuttings, which strike without the slightest difficulty.

Encravines.—Paxton’s Magazine of Botany, vol. vii., p. 195; and our jig. 4, in Pl. 20. 
Speciric Cuaracter.—Leaves obovate. Flowers much longer than the leaves. 
Description, &¢c.—This is a very beautiful hybrid, raised apparently between C. pulchella and some of the 
other species. It is a very elegant little plant, and an abundant flowerer; but much less robust than most of 
the other kinds. It does not strike readily from cuttings, and on this account it is generally propagated by 
grafting on some of the more robust species. The operation should be performed very early in spring, as soon as 
the plant begins to grow; the stock should be O. speciosa or C. pulchella, and the graft should be inserted either 
close to the base of the stem, or not more than three inches from it. When the plant is grafted, it should be 
placed in a slight heat, such as that afforded by a bark bed in which there is a very moderate degree of fermen- 
tation ; or, if this cannot be procured, the pots may be placed in a spent hot-bed, or in a bed of sand on hot-water 
Pipes, such as that described and figured in my Amateur Gardener’s Calendar, p. 191.

This is a remarkably handsome hybrid, raised by Mr. Beaton between C. speciosa and C. pulchella. It has 
great “boldness of habit and luxuriance of stems and branches.” Mr. Beaton has given a detailed account of bis
