Glabrous. Stems 2-3 ft., at top very slender triquetrous. Leaves inconspicuous, 

 uppermost 4-6 (rarely 8-10) in. long, erect, narrow. Umbel rays 3-6, slender, 

 2-4 in. long, sometimes again divided; bracts -2 in,, leaf-like. Spikelets % by 

 -jL in. j wings of rhachilla narrow-oblong, hyaline, disappearing. Glumes somewhat 

 remote, in fruit not imbricate, ovate-oblong, 3-5-nerved, back green, sides brown 

 nerveless. Stamens 3 ; anthers linear-oblong muticous. Nut trigonous, ashy-black ; 

 style shorter than nut ; branches linear, long. Somewhat resembling slender forms 

 of C. tegetum, but the narrow evanescent wing of rhacheola would remove it out of 

 the present series altogether.
