 oblong, longitudinal; panicle short, scarcely dilated, and shortly 

 filiform.

This Acacia, as far as known, has a restricted geographical 

 distribution, having been collected only in theCounty of Roxburgh, 

 where it forms in the distance black bands at the base of the 

 ranges. It can scarcely be called an attractive Acacia owing to 

 it sooty appearance, due to the presence of a Fungus (supra), and 

 the viscid character of the phyllodes. 



A viscidula A. Cunn., also occurs in the same locality, but the 

 differences between the two trees are too pronounced to need to 

 be particularised here. 



The shape of the phyllodes, together with the venation, resembles 

 somewhat those of A.dictyophleba F.v.M. Although collected by 

 me as far back as 1893, I hesitated to describe it, thinking 

 perhaps it might be a form of Bentham's A. ixiophylla (Lond. 

 Journ. Bot. i. 564). When visiting Kew Herbarium in 1904, I 

 compared my material with Hooker's specimens, and concluded 

 that it was distinct from his on the following features : — (a) It has 

 twice as many flowers in the head. (b) The phyllodes have 

 quite a different shape and are larger in size, (c) The inflorescence 

 is not in racemes. (e) The pods are much longer and 

 narrower. In Bentham's classification this species belongs to the 

 series of Plurinerves and subseries Nervosa?, the phyllodes being 

 viscid, with several prominent nerves and reticulations between 

 them. Of the sixteen species placed by him in this section, it is 

 more particularly associated with A. viscidula A. Cunn., A. ixio- 

 phylla Benth., and A. dictyophleba F.v.M., these species being 

 very viscid, with numerous nerves or veins. The differences 

 between it and A. ixiophylla have already been detailed (supra). 

 A. viscidula has narrow-linear longer leaves and a pubescent pod, 

 and a different inflorescence; whilst A. dictyophleba has larger 

 phyllodes and altogether a longer pod. In botanical sequence it 

 might be placed between A. viscidula and A. ixiophylla.
