MACLOSKIE : REVISION OF FLORA PATAGONICA. 37 



flowers to be entirely like those of A. flavidula, and the floral glume 

 papilliferous. In other respects, apart from their size, I have not been 

 able to see any difference between the two species and, therefore, consider 

 them identical. 



Both were published at the same time. Flavidula, for obvious reasons 

 not being a proper denomination, I deem it better to adopt aberrans as the 

 specific name. 



It may be questioned whether A. Kufuim Speg. should not also be 

 merged in A. aberrans. Having had no chance of examining any speci- 

 men, and the description of the first named, in some particulars, not quite 

 agreeing with A. aberrans, A. Kufuim, I think, at least at present, should 

 be allowed to retain its position as an independent species. Spegazzini 

 collates A. Kufuim with A. montemdensis Spr., while A. aberrans rather 

 reminds of A. umbellata Colla. 



In this connection I wish to draw attention to an error in my previous 

 work "Die Gefasspflanzen der Magellanslander." On page 219, A. 

 Kufuim is said to occur in Magellan and Fuegia, but this applies rather 

 to A. aberrans. D. 



A. ANTARCTICA Hook. fil. Macl., p. 185. 

 Should be deleted, being identical with A. magellanica Lam. 



A. ANTONIANA Gris. Macl., p. 185. 



This species is identical with Calamagrostis Antoniana (Gris.) Hack, 

 and should therefore be transferred to that genus. 



Add Macl., p. 185: 



A. BUCHTIENII Hack, in Fedde Rep., II, p. 69. 



This species has the same habit as Agrostis exarata Trin. (in Macl., p. 

 187) and stands near to that species, but A. exarata differs by having 

 scabrous leaves and very short palea (still shorter than the ovarium). 

 Besides, the fertile glumes are very often awned. In all probability, 

 though, also A. Buchtienii has awned glumes, as the middle nerve of the 

 same ends abruptly in their upper third. To judge by the description, 

 Agrostis santacruzensis Speg. may also stand near to A. Buchtienii but 

 differs from that species by longer ligule (3-5 mm. long), by more lax, 

 more open, and slightly nodding panicle, by its glumes being scabrous at
