MACLOSKIE: GRAMINE/E. 189 



Like A. antarctica Hook, f, but has larger glumes, greater size, and 

 conspicuous palea. 



(S. Chili ; also in Kerguelen I., and in islands off coast of New Zeal.) ; 

 S. Patagon., by RR. Sta. Cruz & Gallegos; Magellan; S. Fuegia; Falk- 

 lands. 



"My specimens have appressed-hirsute peduncles and rachis, glumes 

 subequal, i-nerved, dorsally rough, 4 mm. long; flower small (1.5 mm. 

 long) ; the awn scarcely exceeding the glumes." (Speg.) 



19. A. MOYANOI Speg. 



(Glabrivalve, univalve, muticous.) Grasses densely cespitose, glabrous. 

 Leaves rather plane, narrow, acute ; ligule ovate, dentate. Culms rather 

 tall, clothed to the top. Panicle strict, spathaceous-leafy, rays di- to trichot- 

 omous, laxly rough, naked, i-spiculate at the apex. Spikelets ovate- 

 oblong, acute. Glumes carinulate, dorsally rough, enclosing the shorter 

 glabrous fawer. 



Patagon., in meadows along Rio Carren-leofu. Grass 30-50 cm. high. 

 Allied to A. leptotricha Desv. but distinguished by its usually i -nerved 

 floriglume, and the palea altogether wanting. 



A. MOYANOI MAJOR Speg. 



Culm leafy to the top, panicle secund, virescent; spikelets large (3-3.25 

 mm. long) ; flower larger (2 mm.), more 3-nerved and more rough. 

 Near Carren-leofu. 



A. MOYANOI PLICATIFOLIA Speg. 



Leaves rigid, glaucescent, plicate; spikelets dark-purplish, floriglume 

 very 3-nerved, and often awned on the back. 

 By Rio Chubut. 



A. MOYANOI PUBERIGLUMA Speg. 



Glumes more or less densely pubescent-rough ; flower equalling the 

 glumes. 



By Rio Carren-leofu. 



20. A. NARDIFLORA Griesb. 



Rhizome cespitose, descending, with dense-leaved offshoots. Culm 20- 

 30 cm. tall, smooth, exsert from the pale glabrous sheaths ; ligules acu-
