174 DEYEUXIA SCABRA. 



central short dorsal awn ; scabridus 5-nerved. Palea nearly as long as 

 the glume, trifid at the top. Rhachis produced into a long pencil of 

 hairs, and a circle of hairs round the base of the flowering glume. Scale 

 narrow, acute. Anthers long. Ovary pubescent on the top. DISTRI- 

 BUTION OF SPECIES: QUEENSLAND, NEW SOUTH WALES, 

 VICTORIA, TASMANIA, NEW ZEALAND. 



The present species was collected by Mr. Petrie, on Swampy Hill, near 

 Dunedin, but as it is a common grass in Australia, and having only been found in 

 the vicinity of extensive grass cultivations and of a shipping port, must be con- 

 sidered as a doubtful native until it has been found in other places ; nevertheless, 

 as few collectors have given much attention till recently to this family of plants, 

 it may have been hitherto overlooked. Should this grass prove indigenous to 

 New Zealand, it will be necessary for the purpose of preventing confusion, that 

 the genus Deyeuxia be added to the flora, in consequence of Agrostis parv /flora, a 

 New Zealand species, having been identified with a common North American 

 species, Agrostis scabra, Willd, " Flora Australiensis, VII., 576," and as Hooker 

 in his arrangement of the New Zealand grasses has united Deyeuxia and Agrostis, 

 confusion would arise from having two species with the same specific name, it 

 would therefore be necessary in any future arrangement that such an anomaly 

 should be provided for by separating the two genera. DISTRIBUTION or SPECIES
