[I can see nothing to distinguish this from A. Wickhami, except that 

 the specimens are in fruit, all those hitherto described of A. Wickhami 

 being in flower only. — G. B.]

[Differs from A. stigmatophylla in its rather shorter thick coriaceous 

 phyllodia, in the viscidity of the young shoots, and the thicker, denser 

 spikes, with larger flowers. — G. B.]

anastomosantibus distinguenda. 



[Cunningham's specimen is very bad, which accounts for the imper- 

 fect description which prevented Dr. Mueller from recognizing it. The 

 name is also inappropriate, unless it referred to the character of the 

 tree from which it was gathered. — G. B.]
