Var. micrathera. 



Var. micrathera, Hackel in Cheeseman's Man. N.Z. Flora, 869. 

 Campbell Island ; W. R. Chambers ! Antipodes Island ; T. Kirk ! 



Var. Lyallii occurs on the southern coast of the South Island of New Zealand ; 

 var. micrathera is endemic in the Campbell and Antipodes Islands. 



The species is plentiful and widespread on the main islands of New Zealand, 

 and is equally plentiful in Australia and Tasmania. 



[Agrostis l&ptostachys, Hook, f., Fl. Antarct., i, 94, is most likely identical with 

 this.] 



Deyeuxia setifolia, Hook. f.

 Hook, f., Handb. N.Z. Flora, 329. 



Camp Cove, Auckland Islands ; J. S. Tennant ! H. C. Field ! B. C. Aston ! 



Now first recorded from outside the main islands of New Zealand. The form 

 figured by Hooker does not represent the common and typical state of the species, 

 which is much shorter and stiffer, and has more robust spikelets. 



Plentiful on the mountains of the North and South Islands of New Zealand, 

 and descending to quite low levels in Otago, Southland, and Stewart Island. 



[Agrostis aucklandica, Hook, f., Fl. Antarct., i, 96, is probably identical with 

 this, and, if so, the specific name then applied will have priority.] 



Deschampsia, Beauvais. 



Distribution. — In most temperate and cold regions of the earth. Six species 

 inhabit Fuegia and the Falkland Islands, and one of these extends to Kerguelen 

 Island. 



Deschampsia Chapmani, Petrie.
