one-nerved, ending in an oblique acumen, with the spinula continuous 
along the lower margin. Branches diffusely procumbent, glabrous, 
angular. Heads of flowers usually twin. {G. Don.)

Reg., t. 634. 
Specific Character. — Stipules small, caducous. Phyllodia linear, 
Description, &c. — A rather elegant plant, the habit of which differs widely from the general growth of 
Acacias, as its branches spread out diffusely and hang down on every side. The heads of flowers are not very 
large, but they are produced in very great abundance. The species was introduced in 1818. 
6.— ACACIA DENTIFERA Benth. THE TOOTHED ACACIA. 
Engravings. — Bot. Mag., t. 4032; The Botanist, t. 179 ; and our 
jig. 1, in PL 26. 
Specific Character. — Branches angular. Phyllodia elongated, 
linear-lanceolate, falcate, very acute, penni-nerved, not glandular, 
attenuated at the lower part. Racemes elongated, many-flowered. 
Legume cylindrical, straight. 
Description, &c. — ^A very graceful species with unusually long racemes of flowers, which are of a full yellow, 
rather large, and highly fragrant. These racemes, however, Mr. Bentham observes, sometimes become leafy 
branches, and hence assume quite a different character to other racemes on the same plant. The species takes 
its name from the dried remains of the stipules, which when young are fine and thread-like, attaining a considerable 
length, but which break off soon after the flowers expand and leave a portion, which thickens and hardens into 
the form of a double tooth at the base of the leaves. The plant is a native of the banks ‘of the Swan River, 
whence it was introduced in 1840. 
OTHER SPECIES BELONGING TO § 1, THE STIPULES OF WHICH ARE NOT SPINESCENT. 
A. SULCATA Dec. 
A small heath-like shrub, with brownish wrinkled branches, which are densely covered with very slender rigid 
leaves, furrowed deeply from the base to the point. The peduncles of the flowers are shorter than the leaves ; and 
the heads of flowers are not larger than peas. The species was introduced in 1803 from the south-west coast of 
New Holland. 
A. VERNICIFLUA Cmn. 
This species is the same as that figured under the name of A. virgata in the “ Botanical Cabinet ” of Messrs. 
Loddiges. It is a slender twiggy shrub, remarkable for a glutinous substance which covers both the leaves and 
stems. The flowers are in rather small heads ; and the phyllodia are long, falcate, and widely apart. The species 
is a native of New South Wales, near Bathurst, and it was introduced in 1823. 
A. GRAVEOLENS Ctmn. 
This species is nearly allied to the last, but it differs in having a much handsomer foliage, and a very powerful 
odour. It was introduced in 1833. 
A. STRICTA Willd. 
An upright shrub, with very few branches, large phyllodia, and projecting cup-like stipules, which run down 
the stem so as to form a kind of wing. The species was introduced in 1790. 
A. LANIGERA Gunn. 
An upright shrub, with the heads of flowers on very short peduncles. The phyllodia are moderately long,
