Gramina.] SUBANTARCTIC ISLANDS OF NEW ZEALAND. 477 



ovatae, acuminatae, subaequales, spicula tertia parte breviores ; inferior 1-nervata, 

 superior 3-nervata. 



Glumae floriferae ovatae, acuminatae, dorso ubique molliter scabridae, basi 

 baud lanatae, plerumque 5-nervatae, nervo intermedio saepe obscuro. 



Flosculi hermaphroditi ; stamina 3 parva. 



Auckland Islands ; B. C. Aston ! J. S. Tennant ! The Snares ; T. Kirk ! 



Three specimens were collected at Carnley Harbour. Mr. Kirk's specimen is 

 solitary. 



Hybrids between this and Poa foliosa. Hook, f., are probably not uncommon, 

 as intermediate forms collected (in 1909) by Mr. Aston show. 



This is probably the plant referred to Poa anceps, Forst., by T. Kirk in Trans. 

 Austral. Soc. for Advancement of Science, vol. iii (1891), 231. 



Mr. B. C. Aston has now (January, 1909) collected a number of specimens of 

 this species on the Snares, and also on Antipodes Island. 



Poa Hamiltonii, T. Kirk. 



Poa Hamiltonii, T. Kirk in Trans. N.Z. Inst., xxvii (1895), 353. 



Macquarie Island ; A. Hamilton. 



I am unacquainted with this species, which Mr. Kirk considers to be allied to 

 Poa foliosa. Hook. f. There is no specimen of it in the Kirk herbarium, now de- 

 posited in Victoria College, Wellington. Macquarie Island was not visited by the 

 expedition, 



Poa litorosa, Cheeseman. 



Poa litorosa, Cheeseman, Man. N.Z. Flora, 1156. Festuca scoparia, Hook. f. 

 (in part), Fl. Antarct., i, 98 ; Fl. Nov. Zel., i, 308. 



Auckland Islands ; B. C. Aston ! J, S. Tennant ! L. Cockayne ! H. C. Field. 

 Campbell Island ; W. R. Chambers ! (an ergotised state). 



Endemic in the Auckland and Campbell Islands, where it appears to be the 

 dominant upland tussock-grass. 



The species is very closely allied to Poa novarae, Reichardt, of which I have 

 seen only two small specimens, from the St. Paul and New Amsterdam Islands, lent 

 me for examination by Mr. Cheeseman. 



Poa Astoni, Petrie. 



Poa Astoni, Petrie in Trans. N.Z. Inst., xxxviii (1906), 423 ; Cheeseman, Man. 

 N.Z. Flora, 1155. Festuca scoparia, Hook, f, (in part), Fl. Antarct., i, 98 ; 

 Fl. Nov. Zel., i, 308 (in part). 



Auckland Islands ; B. C. Aston ! J. S. Tennant ! T. Kirk ! L. Cockayne 

 (1,000 ft.) ! 



The species extends to the main islands of New Zealand, where it is plentiful 

 on the coasts of the South and Stewart Islands. 



The Auckland Island form has long acuminate flowering-glumes that recall 

 those of the fescues.
