Planta crespitosa. Radicis fibre dense, pallide, compresse, spongiose. Culmorum bases incrassate, 

 vaginis exaridis elongatis pallidis laxe vestitae. Culmi 1J-2 pedes alti, crassitie pennae Columbine, tereti- 

 usculi, altero latere paullo magis depresso, altero inequaliter costulato, striati, in sicco nonnihil torti, non 

 scabri, basi sola foliosi. Vagina ratione lamine breves, striate, compresse, leves, altero latere membrana- 

 cee lacero-dehiscentes, in laminam continue. Folia culmo aliquanto breviora, 1^ lin. lata linearia, acumi- 

 nata, carinata et basin versus complicata, glabra, levia, margine scabra, flaccida, glauca. Capitulum ter- . 

 minale, magnitudine nucis moschate, subglobosum, densum. Involucrum 4-6-phyllum, foliolis a basi 1J 

 lineam lata planiuscula ciliata, in acumen carinatum continue attenuatis, totis herbaceis et rigidis patulis, in- 

 ferne ciliatis apicem versus serrulato-scabris, quorum majus vix bipollicare, reliqua ad \-\ polliccs decrescuut 

 minoraque capituli ambitum intrant. Spiculm per fasciculos 3-4-stachyos sessiles distribute, conferte, omnino 

 sessiles, primum pallide virescentes, demum ferruginese, glabre, lanceolate, compresso-ancipites, acuminate, 

 incurvae, primum arete imbricate, sub fructu apice dehiscentes. Squamm omnino distiche, ovate, chartacee, 

 uninerves, carinate, septenaa ; quatuor inferiores steriles, breves, magnitudine tamen crescente, acute ; quinta 

 precedente majore 1^-1, sub fructu 2 lin.longa, longius acutata; sexta ejusdem forme sed paullo longior et 

 angustior magisque acuminata, teneriorque convoluta, amplectens margine baseos pistillum apiceque stylum 

 arete retinens, per se quidem sessilis, sed sinu recondens squamam septimam minorcm teneriorem, oblongam, 

 acutam, convolutam, stamina continentem. Pistillum unum in axilla squame quinte. Stylus longissimus, 

 squamam sextam excedens, filiformis, glaber, simplicissimus, apice semel bisve contortus acutiusculus, basi 

 strictura insertus vertici ovarii spongioloso capituliformi ; ovarium oblongum, trigonum, perigynio sexseto 

 cinctum. Caryopsis obovata, seminis papaveris magnitudine, utrinque convexa, subtilissime punctulato-

 convexo carinato rnguloso coronata, basi perianthii setulis 4-6 triplo brevioribus retrorsum hispidis fundo 

 conjunctis stipitata, primum lutea, dein fusca. Perigynii exterioris lacinule albe, filiformes, caryopsi multo

 brunnea, squamam sub anthesi aequantia ; antherm lineares, apiculate, bilocellate, lutce, basi veluti in 

 stipitem sterilem filiformem attenuate ejusque opera filamento strictura argute intercedente imposite, ita
