proved that another of the North European grasses is to be added to the 

 "pretty many" previously known which, in a typical or modified form, 

 recur in the peraustral parts of S. America. D. 



Add Macl., p. 196: 



Calamagrostis erythrostachya Desv. occurs also in North Patagon., 

 Territory of Neuquen. 



Add page 196, after line 8 from foot: 



CALAMAGROSTIS FALKLANDI^ Steud. 



Root fibrous, cespitose. Culm simple, erect, short, 10-12 cm., with finely 

 pubescent sheaths. Radical leaves flat, very narrow, striate, acuminate, 

 not equalling the stem, smooth. Panicle spike-like, rays solitary or paired, 

 i-2-flowered spikelets sub-linear. Glumes 2, thin, exceeding the flower, 

 which is hairy at base. Lower valve dorsally scabrid, awned ; rudiment 

 of a second flower or not.

C. MACLOVIANA Steud. 



Root cespitose, bearing leafy fascicles, partly sterile. Culms short, 

 scarcely equalling the leaves, which are broad at base, terete, rigid, pun- 

 gent above, 10-12 cm. and glabrous. Panicle spike-like, at length exsert, 

 with few rays; spikelets short-stalked. Glumes lanceolate, keel scabrid, 

 flower hairy at base ; upper valve shorter than the flower ; rudiment small 

 or none.

Also in the Falkland Ids., Port Stanley and in N. W. Patagonia by Rio 

 Manso. 



ERIACHNE R. Br. 



E. malouinensis Steud. Macl., p. 197, should be deleted. This genus 

 is certainly not represented in the flora of the Falkland Is. It is however 

 impossible to determine the systematic position of the plant which was 

 erroneously referred to the genus, as we have no authentic specimen of 

 the Falkland plant.
