C. cimBarus n. sp. Rhizomate horizontal; culmo basi subtuberoso, plurifoliato, 
triangulari, angulis acutis; umbella composita ; involueri phyllis firmis, erectis; squamis 
carinatis, latere nervosis, margine latis, hyalinis, punetulato-ferrugineis ; caryopsi tri- 
gona; stylo brevi profunde trifido: filamentis marginatis vel limbatis, hyalino-ferru- 
ginels. 
Rhizoma horizontale, nodis parum incrassatum, radicibus longis, filiformibus, 
firmis. Culmi basi subtuberosi, graciles, plurifoliati, rufescentes, 35 cm. alti, trian- 
gulares, angulis acutis versus apicem perminultissime serrato-dentatis, lateribus sul- 
catis. Folia basi breviter vaginantia plurima, fuscescentia, coriacea, firma, acuminato- 
subulata, margine carinaque serratula, culmo breviora. Involuerum pentaphyllum, 
phyllis duobus infimis longioribus, alteris radios æquantibus, folio conformibus. 
Umbellæ radii alteri ad 3 em. elongali, apice polystachyi, alteri abreviati aut sessiles, 
omnes subtriangulares, compressi, basi bracteati. Spiculæ pedicellatæ, bracteatæ, lan- 
ceolato-elongatæ, compressæ 14-18 floræ, alternatim dispositæ. Squamæ remotæ, 
crassiusculæ, ellipsoideæ, dorso convexæ. mucrone crasso, longo, parum incurvato, 
carina distincta viridula, lateribus subquinquenerviis, viridulo-fuscescentibus, margine 
lata, basi quasi auriculata, membranacea, hyalina, punctulato-ferruginea. Stamina 
tria filamentis dilatatis, marginalis, caryopsi adpressi, illam æquantibus, apice recur- 
vatis; antheris linearibus, longis, apice papilloso-appendiculatis. Caryopsis squama 
parum breviore, trigona, ovato-ellipsoidea, basi attenuata, apicata, lateribus concavis, 
lutea. Stylus brevis, usque fere ad basin trifidus, stigmatibus longe exsertis.
