Mr. Cheeseman remarks on specimens I sent him — " It is unusual for 

 these to have such a plentiful supply of male flowers at the top of the female 

 spikelets." 



Ageratum meadoAv, Sunday Island. 



New Zealand. 



Carex Forsteri, Wahl. 



I follow Pastor G. Kukentlial in treating C. semi-Forsteri, C. B. Clarke, 

 as not a distinct species. 



My specimens appear to difier from New Zealand ones in having all the 

 spikelets compound, and in the possession of smooth utricles with short 

 beaks. Mr. Maiden, of Sydney, informs me that the form is closely allied 

 to the Norfolk Island C. neesiana, Endl. (= C. dissita, Sol., var. neesiana 

 (Endl.), Kuk.). Under these circumstances I feel justified in giving it a 

 varietal name.
