spicuous, at least one third as long as the rather short truncate floral 

 glume. (Fig. in Brit. & Br. i, 159.)

Erect, cespitose, 5-60 cm. tall, nodding or inclined, somewhat dense-

 scabrid on the keel, twice as long as the flower, 

 which is glabrate at base. Floral glume trun- 

 cate, 4-cuspidate, 5-nerved with an awn, ex- 

 ceeding the glumes. Palea small. Scales ob- 

 long, scimeter-shaped, subacute (Fig. 35). 



Swampy land, abundant and elegant. Cho- 

 nos and Fuegia to Cape Horn ; Churucca ; 

 Falklands [Kerguelen I.]. (Possibly a var. 

 of A. magel/amca.] 



5. A. ANTONIANA GnS. 



Culm 45-90 cm. tall, smooth. Leaves con- 

 volute-filiform, rough, often 30 cm. long, strict ; 



Hgule long. Empty glumes 6 mm. long, Agrostis antarctica. Inflorescence 

 ,. n 1-11 and spikelet with awn. (Flora 



slightly exceeding the flower, purplish dorsally ; antar c tica ) 

 awn rather long. Floral glume 4-toothed. 



Near Calamagrostis, but distinct by the sterile glumes being broader, 

 acutish, awned dorsally below the middle. 



(Andes of Peru ; Argentina) ; Patagonia (?).

Culm erect, strict, smooth, 50 cm. tall. Leaves very narrow, acute, 

 scabrid, 6 cm. by i mm. ; ligule hyaline, oblong. Panicle contracted ;

 flowers ; floral glume usually awned, the awns not exceeding the glumes. 



Magellan ; Fuegia. 



A yellowish specimen represents the typical form, the floral glume 

 awned ; a violet specimen represents the muticous form.
