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

 Campbell Island ; W. R. Chambers ! (from this habitat only a single viviparous 

 specimen was secured). 



Endemic in the Auckland and Campbell Islands. 



Agrostis, Linn. 



Distribution. — All parts of the world, penetrating into the arctic and antarctic 

 zones. 



Agrostis magellanica, Lam.

 Hook, f., Fl. Antarct., i, 95. 



Auckland Islands ; L. Cockayne ! Campbell Island ; W. R. Chambers ! 



The species has been already recorded from the Antipodes and Macquarie 

 Islands, and from the head of the Clinton Valley (Lake Te Anau). 



It occurs in Chili, Fuegia, the Falkland Islands, Kerguelen Island, Marion Island, 

 and Heard Island. Its remarkable distribution makes it one of the most interesting 

 grasses known. It varies greatly in length and robustness. 



Agrostis subulata, Hook. f.

Auckland Islands ; T. Kirk ! F. R. Chapman ! (January, 1890). Campbell 

 Island ; Hook. f. (loc. cit.). 



This grass was not met with on the expedition. In the writer's herbarium 

 there are several very small specimens, received in 1890 from T. Kirk and F. R. 

 Chapman. These evidently belong to the species described and figured under the 

 above name in Fl. Antarct., vol. i. I consider Bentham's A. Muelleri — a species 

 published in 1878 — identical with Hooker's plant. 



The Auckland Island specimens have a shorter ligule than tnat present in 

 specimens from the mountains of the main islands of New Zealand, but in no other 

 respect, except reduced size, do they differ from typical forms of the species. I 

 have seen no trace of a palea in the florets dissected by me. 



This species occurs on the highest mountains of Victoria ; in New Zealand it 

 ranges from the Ruahine and Tararua Mountains to Campbell Island. 



Deyeuxia, Clarion. 



Distribution. — Temperate regions of both hemispheres ; especially abundant in 

 Andine South America. Many authors place the species herein noted in the genus 

 Calamagrostis, Roth.
