sometimes cause the death of stock by penetrating the 



entrails froni outside of the body.

May, Lennard, and Isdell Rivers (W.V.F.).

6L E. pauciflora W.V.F. n. sp. 



Rhizome perennial, shortly creeping and somewhat knotted, 

 woolly, tomentose ; stems erect or ascending ; filiform, 

 and along with the leaves, silky ; hairy, the nodes bar- 

 bellate ; leaves chiefly basal, narrow, often almost setacous, 

 convolute, finely i^ointed, erect, shorter than the stems, 

 the outer ones reduced to broad mucronate-acute sheaths ; 

 ligula barbellate ; spikelets 1-3, pedicellate ; outer 

 glumes acute, 7-9, curved, thin, purplish, keeled, glabrous 

 or rarely scantily hirsute along the keel, margins often 

 scabrous ; flowering glume slightly shorter, narrow densely 

 silky-pubescent and terminating in a fine curved awn ; 

 palea silky-hairy, with two prominent nerves on each 

 side and tapering into a rather long rigid fruit. 



Edkins Range (W.V.F.). 



Stems, including the inflorescence, not execniding 4ins. in 

 height. Pedicels 2in. or less. Outer glumes 2^ lin. 

 long. Awns ^-Jin. 



In sandy soil. The species probably attains greater dimen- 

 sions than already detailed. All grains in the specimens 

 are diseased, they being filled with black granules which 

 have caused them to assume an oblong- cylindrical form, 

 black in colour with longitudinal whitish stripes or pure 

 black. They attain a length of two lines.
