and even when it is killed to the ground by frost, it will frequently spring up again the following year. It succeeds 
I best, however, when planted in the free ground of a conservatory, where, under favourable circumstances, it will

*1 attached to the phyllodia, particularly when the tree is trained against a wall. It is a native of Van Diemen’s 
f Land, whence it was introduced in 1808. In its native country it is called Black- wood.

Description, &c. — This very handsome plant was one of the first species of the genus brought to England from 
New South Wales, and it was introduced in 1789. In a greenhouse it flowers from February to April ; and it is 
ornamental, not only in its flowers, but in its leaves, which are of a dark green, beautifully tipped with pink. 
OTHER SPECIES BELONGING TO § 2. 
A. UMBROSA Curm. 
A very elegant species, which, in its native land, becomes a tree twenty-five feet high, and, consequently, 
capable of affording shade. It flowers in spring, and its blossoms, which are of a very pale yellow, almost white, 
are powerfully fragrant. The plant was introduced in 1823. The phyllodia are much larger than in most other 
species of the genus. 
A. VESTITA Cunn. 
A soft-furred shrub of gi’eyish-gi’een hue, much branched in the upper part. The younger branches are so 
much covered with hair as to he quite shaggy. The flowers, which in most of the species of this division are of a 
very pale yellow, almost white, are, in A. vestita, of the same deep orange hue so frequently seen in the species 
belonging to the first subsection of the genus. 
A. PROMINENS Cunn. 
This very showy plant is called in New South Wales the Nepean Wattle Tree, from its being found in the 
immediate vicinity of the Nepean river, and from Wattle being the general name given to all the Acacia trees in 
Australia. This species is remarkable for the small size and great number of its heads of flowers, which give it an 
exceedingly gay and brilliant appearance. It is a tall slender shrub, often growing ten feet high, and it was 
introduced in 1835. 
A. CUI.TRIFORMIS Cimn. 
A curious plant, which, though it will attain a large size, will yet flower while very small. It is, however, 
perhaps more curious than oniamental, as the oddly-shaped leaves, which seem from their name to be supposed to 
, hear some resemblance to the coulter of a plough, are crowded so closely together as to be rather unsightly. The
