OF ORNAMENTAL EXOTIC PLANTS, 127 
eighteen or twenty feet high, but in England it is only a moderate-sized bush, unless planted in the free ground 
of a conservatory. There are two varieties of this species which only differ in the length of the leaves, and both 
are figured in the “ Botanical Magazine.” Two plants are also figured under this name in ‘“ Paxton’s Magazine 
of Botany,” but one of these (see vol. xii., p. 269,) is evidently not even any variety of A. longifolia, as it has its 
flowers in balls and not in spikes. Possibly it may be A. subulata Bonpl., the phyllodia of which are very long 
and linear, and which has the flowers disposed in globose heads arranged in racemes

OTHER SPECIES BELONGING TO § 3. 
A. RUSCIFOLIA Cunn. 
This species is very nearly allied to A. verticillata, from which it is distinguished principally by its downy 
branches, and somewhat paler flowers. It is a very ornamental species, and well deserving of cultivation. It was 
introduced in 1819. 
A. MGESTA JZindl. 
This very singular species has been called by Dr. Lindley the Mourning Wattle, on account of the singularly 
dull and almost blackish-green of its phyllodia. Its flowers are also in very close spikes, and more singular than 
ornamental. Like most of the other species of the genus, it is a native of Australia, whence it was introduced 
in 1845. 
There are many other species belonging to this division, but as they are not figured in the common botanical 
periodicals, and as they are very seldom seen in collections, it has been thought unnecessary to describe them here. 
SECT. IL—CONJUGATO-PINNATA. 
Sectronan Caracter.—Leayves with one pair of pinne, each pinna bearing few or many pairs of leaflets. (G. Don.) 
Description, &c.—The species included in this section are very seldom seen in collections, with the exception 
of the one called A. pulchella, The flowers are generally in globular heads. 
13.—ACACIA PULCHELLA &. Br. THE PRETTY ACACIA, 
Eneravines.—Lodd, Bot. Cab., t. 212; and Paxt. Mag. of Bot., | Pinne bearing five or seyen pairs of oblong-oboyate obtuse leaflets 
vol. iv., p. 198. | Petioles short, bearing a pedicellate gland between the pair of pinne 
Speciric Cuaracter.—Smoothish. Spines stipular, straight, slender. | Heads of flowers solitary. (@. Don.) 
Description, &c.—A yery pretty little plant, forming a small prickly bush, with great abundance of fragrant 
- flowers, and very delicate pinnate leaves. The flowers are in globular heads, each head being produced alone 
The species is a native of New South Wales, whence it was introduced in 1803, 
SECT. IIJ.—SPICIFLORA. 
Sectionat Cuaracter.—Leavyes bipinnate, with few or many pairs of pinne, each pinna bearing few or many pairs of leaflets. Flowers 
in spikes or balls. (G. Don.) 
Description, &c.—In this section are some of the handsomest halfhardy species of Acacia, particularly 
A. lophantha and A. dealbata, though the last seems oddly enough placed in a section called Spiciflore, as its 
flowers are always produced in globular heads.
