A. \aurifblia Willd. {Labill. Nov. Cat., p. 68. t. 68.), Mimbsa sirnplicifblia I,., has the dilated petioles 

 obliquely ovate-oblong. It is a native of the Friendly Isl tnds and the New Hebrides, as well as of 

 New Caledonia, where it forms a tree from 20 ft. to 25 ft. 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-racemosa?. Floivers 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. melandnylon R. Br. {Bat. Mag., t 1659., 

 figs. 378, 379.) has the dilated petiole lanceo- 

 late-oblong, rather falcate, 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, attaining the height of 10 ft or 

 12 ft., after being 2 or 3 years planted out A 

 fine tree of this species stood out three winters, 

 in the garden of the Horticultural Society, as a 

 standard, but was killed, or nearly so, by the 

 severe frost of January, 1836. A plant against 

 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. 



A. heterophylla Willd., Mimbsa heterophylla 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 of 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 

 palace at Caserta, near Naples, it was 50 ft. high in 

 1834-. 



A. myrtifolia Willd., ^ 



Mimdsa wzyrtifdlia Sm., 

 A. lanata Lodd. {Bot. M. t 

 S02., 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 petioles 



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. Spicatce. Floivers disposed in cylindrical Spikes. Stipides usually ivanting, 

 or, when present, small and not aculeate. (Don's Mill., ii. p. 406.) 



A. Oxycedrus Sieb. {Bot. Mag, t. 2928.), A. /axifblia Lodd. {Bot. Cab.,t. 1225., and our figs. 382,383 )
