A. laurifolia Willd. (Labill. Nov. Cal., p. 68. t.68.), Mimdsa siraplicifodlia L., has the dilated petioles 
obliquely ovate-oblong. It is a native of the Friendly Islands and the New Hebrides, as well as of 
New Caledonia, where it forms a tree from 20 ft. to25 tt. in height. It was introduced in 1775; but, 
though a most desirable species for a conservative wall, it is not common in collections. 
B. Capitdto-racemdse@, Flowers collected in globose Heads ; the Heads disposed 
in Racemes along the axillary Peduncles. Stipules of all the Species nearly 
obsolete, or, when present, not aculeate, (Don’s Mill., ii. p. 404.) 
A. melanéxylon R. Br. (Bot. Mag., t. 1659., 
figs. 378, 379.) has the dilated petiole lanceo. 
\ late-oblong, rather faleate, obtuse, quite en- 
| tire, and many-nerved. The flowers are few, 
; and disposed as in the figure. This is a native 
| of New Holland, and also of Van Diemen’s 
| » Land; and, in mild winters, it will grow in the 
open air, in the neighbourhood of London, 
as a standard, attainin® the height of 10 ft. or 

NG 12ft., after being 2 or 3 years planted out. A 
\\\ fine tree of this species stood out three winters, //}, 
: \\, ____ inthe garden ef the Horticultural Society, as a | 
~==2° == standard, but was killed, or nearly so, by the | 
severe frost of January, 1836. A plant against 
5 the wall in the same garden, which had stood 
out since 1831, with no other protection than a projecting coping, was also much injured at the same 
time. Had there been a protection in front, and had the standard been covered with a mat, both 
would have escaped uninjured. In the Norwich Nursery, this acacia stands the winter. 
GC A. heterophglia Willd., Mimdsa heteroph$lla Lam. 
Dilated petioles, linear, attenuated at both ends, 
rather falcate, many-nerved ; there are also, some- 
times, bipinnate leaves at the tops of the branches. 
Heads cf flowers disposed in a kind of raceme ; 2—3 
heads to each raceme, Introduced, in 1824, and, 
probably, tolerably hardy; as, in the garden of the 
sera at Caserta, near Naples, it was 50 ft. high in 
A. myrtifilia Willd., 
Mimdsa myrtifolia Sm., 
A. lanata Lodd. (Bot. M., 
802., and our fig. 380.) 
is a handsome and very 
hardy species, which has 
been in the country since 
1789, and grows to the 
height of 6 ft. or 8 ft.

<==— hasthe dilated fetioles - 
linear ; tapering a little at the base, acute, mucronulate, 1-nerved, quite entire; the heads of flowers 
racemose; and the legumes glaucous from grey powder. The flowers are fragrant, and appear from 
February to June. This species was introduced in 1790, and grows to the height of 8 ft. or 10 ft. 






C. Spicdte. Flowers disposed in cylindrical Spikes. ~ Stipules usually wanting, 
or, when present, small and not aculeate. (Don’s Mill., il. p. 406.) 
A. Oxgcedrus Sieb. (Bot. Mag., t.2928.), A. taxifolia Lodd. (Bot. Cab.,t. 1225., and our figs. 382, 383.) 
has the stipules spinose ; the dilated petioles scattered, or somewhat verticillate, lanceolate-linear, an
