MACLOSKIE: REVISION OF FLORA PATAGONICA. 45 



Add Macl., p. 198: 



AIRA L. 



A. PR^COX L. 



Falkland Is., introduced. Airopsis pracox (L.) Fr. of Macl, p. 195, 

 should be changed into this genus Aira (olim Airopsis, nunc Aira). 

 Airaflexuosa L., added by Macl., is identical with Deschampsia flexuosa, 

 and should, in my opinion, be deleted. D. 



A. ATROPURPUREA Wahlb. Macl., p. 198. 



Some time ago I stated that the figure of this species given in Flor. 

 dus. (sub A. magellanica] agrees exactly with specimens of the same 

 species preserved in the Stockholm Herbarium. I have also expressed 

 the view that this species, in fact, must be transferred to the genus Des- 

 champsia, in accordance with the exposition of the Gramineae in Engler 

 and Prantl Nat. Pflanzen-familien ; viz. its subgenus Vahlodea as already 

 noted in that work. I have not, however, made such a transfer, as that 

 will involve too many changes to be attempted at this time. Descltampsia 

 antarctica is by Skottsberg transferred to Aira. I have carefully ex- 

 amined the species and think it is undoubtedly a Deschampsia. But as a 

 new systematic arrangement of the Grasses is probably coming, we can- 

 not discuss these equations at present. D. 



Macloskie has, according to Desvaux in Flor. Chil., VI, p. 340, put 

 down Aira magellanica Hook. fil. as synonymous with the present species, 

 to which there is no reasonable objection to be made. Though I have 

 not seen a specimen of A. magellanica, J. D. Hooker's reproduction of 

 it in Flora Antarctica, II, Tab. 134, appears to be identical with Aira 

 atropurpurea. D. 



Add Macl., p. 198: 



A. FLEXUOSA Linn. (Syn. Deschampsia flexuosd}. 



Panicles diffuse, glumes rough on rib, upper erose at tip, with central 

 and two obscure lateral ribs ; awn jointed, inserted near the villous base, 

 long; leaves setaceous. D. 



Falkland Is. 



A. SUPERBIENS Steud. Macl., p. 198. 



Being synonymous with Poa fuegiana (Hook, fil.) Hack, (of p. 227) 

 this species should be left out
