154 TWO NEW SPECIES OF ACACIA FROM N.S.W., 



I am of opinion that this species, in botanical sequence, comes 

 in the Subseries Oligoneura of the Series Plurinerves of 

 Bentham, as the phyllodia resemble those, of A. eJongata more 

 than that of any other, and which species falls in that group. It 

 differs from A. elongata, however, in the phyllodia being more 

 elongated and less rigid, and drying a darker green; in the mode 

 of inflorescence, and having considerably fewer flowers in the 

 head; in its very narrow pod, and also in being a less attractive 

 shrub than that species. 



Except in the matter of the phyllodes above alluded to, it is 

 by no means easy to particularise the affinities of this Acacia 

 with the others of this group. Of the seven species described 

 under the Subseries Oligoneura, it is allied perhaps more to 

 A. elongata and A. suhporosa (narrow-leaved variety), and I have, 

 therefore, placed it between these two. It differs from both in 

 its flowers being in racemes instead of on individual peduncles, and 

 also in its having fewer flowers in the heads; and in this latter 

 feature it appears to stand apart from any other Acacia — the num- 

 ber of flowers being so few. The individual flowers closely resemble 

 those of A. cincinnata, F.v.M., but this species belongs to the Group 

 J itlifer (K. It is furthur distinguished from the two above 

 named species by its calyx, petals, pods, arillus and funicle. I 

 should not be surprised if another species or two will yet be 

 discovered to connect if^with the narrow-leaved variety of A. 

 subporosa, F.v.M. 



Acacia difformis, sp.nov. 



(Plate IX.) 



A small glabrous, shrubby tree, 20 to 30 feet (as far as seen), 

 branchlets angular, very frequently quite flattened. Phyllodia 

 oblanceolate, rigid, coriaceous, very obtuse, falcate in the narrow- 

 leaved form, 3 to 5 inches long in the broad variety and 8 inches 

 in the narrow-leaved variety, from 3 to 12 lines broad, one 

 prominent nerve, with a secondary one between it and the upper 

 edge, running from the base of the phyllode to the gland, and
