Hob. South Island — Lake Te Anau; Catlin's Kiver; 

 mouth of the Clutha ; Hindon ; and Kaikorai (Dunedin). 

 North Island — Near Erehwon (Upper Eangitikei). I hear 

 from Mr. N. E. Brown, of Kew, that this species is the 

 plant, gathered near the base of Tongariro by Colenso, and 

 in the South Island by Dr. Lyall, to which Sir Joseph 

 Hooker refers at page 68 of the Handbook as a probable 

 fourth species of Gunnera. It grows only in ground saturated 

 for most of the year with water, and is generally accompanied 

 by masses of Sphagnum. 



Agrostis multicaidis, Hook. f. 



This species was gathered by me in January of the present 

 year at the head of the Clinton Valley (Te Anau). It is a 

 native of Campbell Island, and has now been met with for the 

 first time on the mainland of New Zealand. I am not sure 

 that there are sufficient grounds for merging this species in 

 A. antarctica, Hook, f., as Sir Joseph Hooker has done in 

 the " Handbook of the New Zealand Flora." At any rate, the 

 plant from the Clinton Valley differs widely from that figured 

 as A. antarctica, Hook, f., in vol. ii. of the " Flora Ant- 

 arctica."
