DE. F. MUELLEE ON AUSTEALIAN ACACIJS. 135 



Gulf Australise boreali-occidentalis a beato Cunningham imperfecte 



collecta. 



[Dr. Mueller is right in referring this to the plant gathered by A. 

 Cunningham at Cambridge Gulf. It is very nearly allied to M. mela- 

 noxylon ; but the flower-heads appear to be always solitary, on slender 

 peduncles, and much smaller than in that species, and the pods more 

 straight, broader, thinner, and shorter. The phyllodia are also usually 

 more glaucous. — G. B.]

Phyllodia 2-4" longa. Pedunculi floriferi semunciales vel breviores. 



Spicce circiter 4'" longae, floribus minutis. 

 A.filifolice Benth, proxima. 



[A good species. The striae of the phyllodia are like those of ^. 

 aciphylla, Benth. ; but the phyllodia are very much more slender, and not 

 pungent. The spikes when in bud are like those of A. xylocarpa, 

 the angular corollas projecting considerably above the calyx. — G. B.]
