MACLOSKIE : REVISION OF FLORA PATAGONICA. 47 



Patag., Ill, p. 193 the difference between them is of no great impor- 

 tance. Having had no opportunity of examining any specimens of D. 

 tenella, it seems to me to be more convenient to let it remain, for the 

 present, as an independent species, as stated by Macl., p. 203. 



Add Macl., p. 201 : 



D. ANTARCTICA (Hook, f.) Desv. var. BREVIROSTRATA Hack. 



Vide Flor. Ant., II., p. 377. Cf. etiam F. Kurtz, Collectanea ad Fl. 

 argent., pp. 259-260. 



Char, of var. Culms densely cespitose, 1-3 in. long, erect or procum- 

 bent, leafy; leaves long, sheathing, linear-subulate, margins involute; 

 panicle large, 4-6 in., profuse; rays fasciculate, capillary; and pedicels 

 long, scabrous. Spikelets lanceolate, narrow, and 2-flowered ; with setula 

 of a third. Glumes lanceolate, scabrid, ciliate, acute, exceeding the flowers. 

 Lower valve bifid, awn straight, slightly exceeding the glume. 



Falkland Is.; Kerguelen Land; S. Patagonia, Upper Rio Gallegos. 



The species extends considerably further north than stated by Maclos- 

 kie as I have, myself, found it to be common at fresh-water lagoons in 

 the Sta. Cruz Territory, and Spegazzini notes it from N. Patagonia. D. 



D. FLEXUOSA (L.) Trin. Macl., p. 201. 



Syn. Aira vestita Steud. 



The range of the species is more extensive than that given by Macloskie. 

 It is rather common in the western part of the Sta. Cruz Territory in the 

 lowlands as well as in the mountain slopes, up to an altitude of 700 m., 

 and occurs not less frequently in the upper part of the Rio Aysen valley 

 from its foot up to 800 m. In open ground it scarcely attains the height 

 of 3 dm., in the forest one to two dm. more. D. 



D. GRANDIFLORA NeCS. Macl., p. 2OI. 



Steud. Syn Glum., I, p. 220 (sub Aira). 



Stated by Steudel to be a Fuegian plant. It has never been rediscov- 

 ered. Very probably identical with Deschampsia Kingii ( H ook. fil. ) Desv. 



D. KINGII (Hook, fil.) Desv. Macl., p. 202. 

 Syn. Aira elatior Steud. Trisetum Dozei Franch. 

 Aira elatior, No. 1222 in W. Lechler, Plantce Magellaniccz agrees with 

 the present species, as I have been able to ascertain by examining a 

 specimen of Steudel's plant preserved in the Stockholm Herbarium.
