leaf, by which means each side is presented to the spectator, gives a 
peculiar aspect to the scenery of New Holland, where these plants 
abound. The immense number of exhaling pores (Stomata) on both 
sides of these, by permitting the escape of a large quantity of aqueous 
vapour, causes a great degree of dampness in the atmosphere in their 
vicinity. | 
InTRoDUCTION ; WHERE Grown; CuLTureE. Introduced in the 
year 1792. It may be propagated easily by cuttings; or by seeds, 
which are plentifully produced by this species, It thrives best ina 
light sandy soil, but will succeed in any. The Acacias require to be - 
very freely watered, during warm dry weather. Our drawing was 
made in the garden of the Birmingham Botanical Society. Mr. 
Loudon, in his inestimable Arboretum and Fructicetum Britannicum 
(now brought to its conclusion) has the following observations on the 
genus Acacia. “This is a very extensive genus of shrubs or trees, 
with beautiful foliage and flowers, and of intense interest to the Brit- 
ish gardener, because, in mild winters, they are found to live in the 
open air, as standards, attain a tree-like size in 2 or 3 years, and 
flower profusely, very early in the spring. They are all of easy pro- 
pagation, either by cuttings or from seeds, either imported or produced 
in this country, and their growth is so rapid, that plants 2 years 
established, have. been known to make shoots 16 feet long in one 
sandy soils, and in sheltered situations, the greater 
number of the specins of Acacia might be grown together as a wood 
or thicket, by which means the plants would protect one another ; 
and though their tops might be annually killed down for 2 or 3 feet. 
by the frost, yet the dead portions being cut off annually, in May, 
the plants would grow again with vigour. An Australian forest might 
not be realized in this way in England, but some allusion might be 
created to an Australian coppice wood.” Vol. II, p. 662. _
