 p. 31, 1845. 



Lord Auckland Group ; d'Urville. 



I know nothing of this variety, and it would probably be impossible to re-identify 

 it unless some of the original specimens were obtainable. The species recorded 

 by Hooker from the mainland as E. clathrata, var. ramulosa, Harv., has sometimes 

 been re-identified as E. acanthophora, Kiitz. ; but there is apparently no doubt 

 that E. clathrata, var. ramulosa, does occur among the New Zealand specimens col- 

 lected by Hooker(i). This plant is now known as E. ramulosa (Engl.), J. Ag.(2).
