Tufted, glabrous. 



Radical leaves few ; much shorter than the culms (usually \ their 

 length), involute, setaceous, erect, wiry, subpungent at the tips ; cauline 

 3 or 4 with long closed sheaths and short blades. 



Culms slender, wiry, erect, considerably overtopping the highest cauline 

 leaf. 



Panicle short (2|-4 cm. long), narrow-ovate to broadly linear ; branches 

 approximate, solitary, immediately more or less subdivided ; lateral pedicels 

 very short. 



Spikelets + 7 mm. long ; florets small ; empty glumes nearly equal, 

 considerably exceeding the florets, dark brown or black, edged with broad 

 pale scarious margins. 



Flowering-glumes membranous with a dense band of hairs a little below 

 the terminal lobes and equalling the delicate scarious acuminate awnless 

 lateral teeth, their lower part almost glabrous or rarely sparsely pilose with 

 3 short tufts of very short hairs close to the base ; awn setaceous, 

 slightly flattened below, erect or bent to one side, not twisted.
