 ad fluraen Warrego a Barton, ad flumen Lachlan's River a Mitchell,

 membraneis et arista capillari prsecipue discrepat. Folia cum 

 petiolis interdum sparse pilosa. Rachis pcdunculis spiculr 

 brevissimis persistentibus et cicatricibus dentata atque ad angulos 

 ciliolata. Arista lacinias interdum conspicue excedens. 



Danthonia triticoides (Lindley in MitchelL Trop, Austr. 365)

dispositis constans, solitaria v. passim geminata. Rachis recta v. 



leniter flexuosa, dorso leniter convexa. Spiculse 4-8-flor0e, sessiles
