A. \aurifhlia Willd. {Labill Nov. Cal., p. fi8. t. 68.), Mlmbsa sirnplicif61ia L., has the dilated petioles 

 obliquely ovate-oUong. It is a native of the Friendly Islands and the New Hebrides, as well as nf 

 New Caledonia, where it forms a tree from 20 ft. to 25 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-racemosce. 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'a Mill., ii. p. 4-04'.) 



A. melandxylon R. Br. [Sot 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 tigure. 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 

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

 fine tree of this species stood out three winters, 

 in the garden ef the Horticultural Society, as a 

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

 severe frost of January, 1S.J6. 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. lietcrophylla Willd., Mimbsa heteroph^Ua 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 haidy ; as, in the garden of the 

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

 1834. 



A. myrtifnlia Willd.,

 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.

 racemoseTar^d^he legumes glaucous from grey powder. The flowers are fragrant and appear from 

 February to June. This speties was introduced in 1790, and grows to the height of 8 tt. or 10 ft. 



C. SpicdtcE. Floivers disposed in cylindrical Sjnli-es. Sfipnles usually wanting, 

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