OF ORNAMENTAL EXOTIC PLANTS.

Bottle-brush Trees by the first settlers in New South Wales, fi’om the disposition of the stamens round the stem 
bearing some resemblance to that of the bristles on the brushes used in cleaning bottles. 
1.— CALLISTEMON VIRIDIFLORUM Dec. THE GREEN-FLOWERED CALLISTEMON. 
Synonyme. — Metrosideros viridiflora Sims. 
Engraving. — Bot. Mag., t. 2602. 
Specific Character. — Leaves linear-lanceolate, stiff, pungent, beset 
with scabrous dots, rather villous when young, as well as the branches. 
Calyx glabrous. (Q. Don.) 
Description, &c. — This species of Callistemon when in flower is so exceedingly like a bottle-brush, as com- 
pletely to explain why the colonists gave the somewhat singular name to the genus. The plant is not particularly 
handsome, from the colom’ of the flowers being green, but it is frequently seen in collections from the singularity 
of its appearance. It was introduced about 1818. 
but villous when young, as well as the branches. Flowers distinct, 
spicate, nearly terminal. Calyx pilose. Petals rather pubescent, 
ciliated. Ovary densely clothed with dotvn. Capsule distinct. (G. Don.) 
2.— CALLISTEMON LOPHANTHUM Sweet. THE CREST-FLOWERED CALLISTEMON. 
Synonymes. — Metrosideros lophantha Vent . ; M. saligna Sims. 
Engraving. — Bot. Mag., t. 1821. 
Specific Character. — Leaves lanceolate, attenuated at both ends, 
mucronate, one-nerved, and feather-veined, glabrous in the adult state 
Description, &c. — This species is a tall shrub with flexible branches and lanceolate leaves, which are narrowed 
at both ends so as to give them a very close resemblance to those of the willow. The flowers are yellowish, and do 
not terminate the branch as in C. viruliflorum, but have a branch appearing beyond. The species is a native of 
New South Wales, whence it was introduced in 1806 ; and when planted in the free ground of a conservatory it 
forms a bushy shrub from four to six feet high. 
3.-CALLISTEM0N SPECIOSUM Dec. THE SHOWY CALLISTEMON. 
Synonyme. — Metrosideros speciosa Sims. 
Engravings. — Bot. Mag., t. 1761 ; and oor Jig. 3, in PI. 30, under 
the name of Metrosideros speciosa. 
Specific Character. — Leaves lanceolate, mucronate, flat, having 
the middle nerve rather prominent, and the lateral ones approximating 
to the margin. Calyxes villous. Capsule four-eelled, tomentose at 
the margin. (<?. Don.) 
Description, &c. — This is one of the most showy of all the species of Callistemon, from the brilliancy of the 
scarlet anthers and the abundance of their golden yellow pollen. The leaves when young are covered with long 
silky hairs, and have a reddish tinge. Like the others, this species is a native of New South Wales, whence it was 
introduced in 1823. When planted in the free ground of a conservatory it forms a handsome shrub ten feet high. 
4.— CALLISTEMON MICROSTACHYUM Lindl. THE SMALL-SPIKED CALLISTEMON. 
Engravings. — Bot. Reg. for 1838, t. 7 ; and our Jig. 1, in PL 30. I spreading, wbitely ciliated on the margin. Calyx pubescent. Sta- 
Specific Character. — Leaves linear-spatbulate, obtuse, very much | mens and petals crimson. 
Description, &c. — This very showy species is remarkable for having the petals of the same brilliant colour as 
the stamens. It is also distinguished by its narrow, spreading, spathulate leaves, which have a margin of white 
hair. The flowers are smaller than those of most of the other species, but this is so far from being a blemish, that 
it gives a degree of elegance to the plant, in which most of the species of the genus are deficient. It should be 
observed that in making cuttings of this species, they should be taken from the points of the young shoots, and if 
possible from young plants. “ This,” it is observed in the “ Botanical Register,” “ is of considerable importance.
