Since my last notice in *' Journ. Bot.," the following additional 

 species and varieties which have come under my notice are now to be 

 enumerated. This is exclusive of Dr. Stirton's new species recorded 

 in Grevillea iii., p. 33, of which unfortunately I have not been able 

 to see any specimens, and therefore cannot in every case speak with 

 certainty as to their value, though several of them, judging simply 

 from the diagnoses given, may be new to science.
