MACLOSKIE: REVISION OF FLORA PATAGONICA. 51 



Gynerium argenteum Nees, Agrost. bras., p. 462 (1829). 



Cortaderia argentea Stapf. Card. Chron., 3 ser., XXII, 346 (1897). 



Cortaderia dioica (Spreng.) Speg., Nov. Add. Flor. Patag., Ill, p. 194. 



This is the full synonymy; the correct specific name is Selloana, not 

 dioica: Ascherson & Graebner explain this in Syn. Europ. Flora, II, p. 

 325- D. 



C. ARAUCANA Stapf. in Gardener's Chronicle, 1897, P- 39^-

C. PILOSA (d'Urv.) Hack. 



Syn. Arundo pilosa d'Urv.; Gynerium nanum Phil. 

 This species occurs also in W. Patagonia, in the upper part of the Rio 

 Aysen valley, in the mountains ; in S. Patagonia, by Lago Argentine in

ERAGROSTIS Beauv. 

 Macl., p. 215 : 



E. ERAGROSTIS (L.) Karst. Macl., p. 215. 

 This name should be replaced by 



E. MEGASTACHYA (Koel.) Link., Hort. Berol., I, p. 187 (1827). 



Syn. Poa megastacyha Koel. Descr. Gram., p. 181 (1802). 

 Eragrostis Eragrostis MacMillan, Metasp. of the Minnesota Valley, p. 



75 (1892). 



E. delicatula Trin. is to be deleted as an independent species, and 

 should be placed as a variety of E. pilosa (L.) Beauv.; thus : 



E. PILOSA (L.) Beauv. var. DELICATULA (Trin.) Hack. 

 (Syn. E. delicatula Trin.) 



Add Macl., p. 216: 



KOELERIA Pers. 



K. BERGII Hieron. 



Sheaths and leaves retrorse-velvety. Spikelets 2-flowered, the 

 flower abortive, and only represented by the rather long racheole.
