Notochloe Domin in Fedde, Rep. X (1911), p. 117. 



„Bentham placed this very remarkable grass under Triraphis but 

 with a query, as the other species of Triraphis have quite a different 

 structure of spikelets. Ferd. von Mueller transfered this species to the 

 genus Triodia and although it surely comes nearer the latter than the 

 genus Triraphis, I think one is not justified in doing so, as cur plant is 

 readily distinguished from the known species of Triodia and this not 

 only in habit but also in the structure of spikelets. Although Notochloe 

 is rightly placed next to Triodia (belonging to the group Pappophoreae), 

 it seems to show some slight relation to the genus Danthonia Sect. 

 Micrathera belonging to the tribe of Avenaceae. It must be pointed out 

 however that Danthonia paradoxa R. Br., the only representative of the 

 most curious Section Micrathera, häs an isolated position as compared 

 with Eudanthonia. 



This curious genus is rendered easily recognisable by the very 

 loose panicle, the solitary large spikelets, the distant, long, shortly 

 tridentate flowering glumes with very prominent nerves and the other 

 charateristics given above. It seems to be limited to the Single species 

 which is rather rare in the Blue Mountains of New South Wales. 



The general aspect of Notochloe mircodon is that of a large Festuca."
