15-30 em. alti; basi incrassata vaginis latissimis brevibus pallidis breviter 
villosulis obtecta ; innovationes numerose elongate sed vaginis arcte 
amplexz. Folia innovationum subdisticha ; lamine patentes vel divaricate 
rigida breves basi subaurieulatze Jate planeque apice convolute pungentes 
circa 2-3 em. longs et quo latissime patent 1-14 mm, late glabra basi 
cartilaginose et ibi a vaginis articulatim rumpentes; vagine glabri mar- 
ginibus sese obtegentibus et persistentibus instruetze ; folia culmea similia. 
Panicula erecta 4-7 em. longa anguste cylindrica fere ad racemum reducta 
vel e fasciculis paucispiculatis subdistantibus composita, pro more panieulie 
rami infimi abbreviati erecti et fasciculos 3-2-spiculatos efformantes parte

Species culmis basi valde incrassatis, foliis subdistichis rigidis pungenti-
