 hairy on both sides, the margins scabrous ; sheaths subcompressed, 

 glabrous except the villous mouth ; ligule very short, ciliate. Panicle 

 4-8 in. long, erect ; rhachis glabrous ; branches filiform, subflexuous, 

 |-1 in. long, often bulbously swollen at their articulation with the 

 rhachis ; racemes 1-1^ in. long, rarely of 3 joints, sometimes of 1 sessile 

 and 2 pedicellate spikelets ; joints about g as long as the sessile spike- 

 lets. Sessile spilcelets reaching ^ in. long, densely villous with red or 

 white hairs ; callus small, densely villous. Glumes 4 ; lower invol.- 

 glnme ovate, acuminate, concave, coriaceous or cartilaginous, 7-nerved,

 5-nerved, the back clothed in the upper part with long hairs, the 

 margins narrowly infolded; lower floral glume as long, membranous,

 lower invol.-glume linear-lanceolate, acute, o-9-nerved, shortly silky ; 

 upper invol.- and lower floral glumes as in the sessile spikelets ; uj^pcr
