Culmus (saltem majoris graminis) decumbens, digitalis — subbipedalis, 

 fere ab ima basi florifero-ramosissimus: ramis tenuissimis, secundis, compo- 

 silis, sicut radioli vaginatis. Folia vaginis non multum longiora (in majori 

 planta non prorsus bipollicaria, sesquilineam lata) , fusco - rubentia , obtusa, 

 glabra. Ligula merabranacea, brevissima. In quovis radiolo, saepe genicu- 

 lato , spica basi vagina involucrata , tenuis , semipollicaris vcl paulo longior. 

 Ariiculi linea paulo longiores, subcuneato-lineares, hinc canaliculati, basi bar- 

 ba adpressa brevi, margine inferne pilosuli. Spicula injerior sessilis, fere bi- 

 linealis, angusta, glabra. Gluma inferior lanceolato-linearis, acuta, bidentata,
