The Manning River specimens belong to the form with very 

 few (1 to 3) pale coloured spikelets, and closely resemble some 

 European specimens; they are less rigid than all West Australian 

 specimens we have seen, with nuts sometimes nearly as long as 

 the glumes.

 Mt. Wilson (Jesse Gregson; April, 1902). 



The Australian species of Uncinia are all southern plants, 

 abounding in the alpine districts of Victoria and Tasmania. 



Mt. Wilson is the most northern localit}^ recorded for the 

 genus in Australia, with the exception of Uncinia dehilior, F.v.M., 

 from summit of Mt. Gower, Lord Howe Island.
