Culms erect, 50 cm. tall, slender, glabrous. Leaves 3-7 cm. long, 2 

 mm. wide, scabrous. Panicle contracted, the branches slender, naked 

 below. Spikelets i mm. long on appressed pedicels, the floral glume two

Punta Arenas ; Beagle Channel ; Brecknock Pass. (Fig. in Brit. & 

 Br. i, 1 60.)

Radical leaves filiform, shorter than the slender culm. Glumes equal, 

 ovate-lanceolate, acuminate, scabrid on the keel, exceeding the flowers ; 

 floral glume erose-truncate, its awn short or none ; palea wanting. 



Magellan ; Falklands. "A specimen of A. canina from Punta Arenas 

 by Dr. Sabatier has some of the leaves setaceous-involute, and others 

 flat-linear ; the former is like A. Falklandica." (Franchet.)

Rhizome creeping. Culms erect, about 60 cm. tall, striate, rough below

 retrorsely scabrid, 12 cm. long. Panicle oblong, lax, flexuose, slightly 

 nodding ; rays capillary, rough, floriferous nearly from base. Spikelets 

 lanceolate, 3 mm. long ; glumes subequal, violaceous and green, the keel
