Gramina.] SUBANTARCTIC ISLANDS OF NEW ZEALAND. 479 



Glumae floriferae angustae, acutae (rarius acuminatae), glabrae, carinatae 

 (carina leviter scabrida), conspicue 5-nervatae ; rachilla perpaucis crispis pilis munita 

 aut paene glabra. 



Palea glumis floriferis tertia parte brevior ; nervis scabrido-ciliatis. 



Auckland Islands, on hills above Carnley Harbour ; B. C. Aston ! Campbell 

 Island ? R. M. Laing (not in flower) ! 



Endemic as above. The specimens examined were transplanted to Wellington, 

 where they flowered. A knowledge of wild specimens may require some modifica- 

 tion of the above description. 



Poa incrassata, Petrie.

 Man. N.Z. Flora, 911. 



Auckland Islands ; F. R. Chapman ! Campbell Island ; B. C. Aston ! 

 Endemic as above, so far as is known. 



Festuca, Linn. 



Distribution. — The temperate regions of the Northern Hemisphere ; less 

 abundant in the south temperate zone, but reaching a high latitude in the case of 

 the undermentioned species. 



Festuca contracta, T. Kirk. 



Festuca contracta, T. Kirk in Trans. N.Z. Inst., xxvii (1895), 353 ; Cheeseman's 

 Man. N.Z. Flora, 919. 



Macquarie Island ; A. Hamilton ! 



The expedition did not visit Macquarie Island, where this species is endemic. 



[A number of specimens of grasses that had not begun to flower were also col- 

 lected, some of which may prove to be new. The date of the expedition was too 

 early for getting satisfactory material of any of these.] 



APPENDIX. 



In January, 1909, Mr. B. C. Aston made a hurried visit to the Auckland, Camp- 

 bell, and Antipodes Islands, and, owing to favourable weather and the more advanced 

 season, succeeded in making a fine collection of the grasses indigenous to the islands. 

 As the results of his exploration are of considerable importance, they are embodied 

 in this appendix. 



Poa incrassata, Petrie. (Amended description.) 



Poa incrassata, Petrie in Trans. N.Z. Inst., xxxiv (1902), 394 ; Cheeseman, 

 Man. N.Z. Flora, 911.
