Of the genus Acacia, reduced as it is by the removal of 
numerous species to other genera, Mr. Bentham has, in his 
valuable Memoir on J/imosee, enumerated no less than 340 
Species in the first volume of the ‘ London Journal of Botany,’ 
published in 1842; and many have since been added. These 
he has, with much skill and judgment, divided into six series, 
and those into sections. Of these, the first three series, con- 
taining 228 species, belong to Australia, and of them 204 are 
phyllodineous species, that is, they have the leaves reduced to 
leaf-like petioles. The third series of the genus, “ Pulchelle,” is 
characterized by being “unarmed, or furnished with axillary 
spines ; the leaves bipinnate; the inflorescence capitate or spi- 
cate and simple; the capitula or spikes axillary, arising from 
a bracteated bud or gemma.” Here eleven species are enume- 
rated, including the present one. 4. Cycnorum, as its name im- 
plies, is an inhabitant of the Swan River settlement, where it 
appears to be common; and Meisner gives two varieties: but 
Mr. Bentham is rather inclined to think that this ought to be 
considered, along with 4. Jasiocarpa and A. hispidissima, among 
the varieties of 4. pulchella of Mr. Brown. Be that as it may, 
it is a very handsome plant, and deserves a place in every green-
