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, 
tin. long, sometimes again divided; bracts 4-2 in., leaf-like. Spikelets 4 by 
Ze in.; wings of rhachilla narrow-oblong, hyaline, disappearing. Glumes somewhat 
Temote, in fruit not imbricate, ovate-oblong, 3—5-nerved, back green, sides brown 
herveless. 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 
* present series altogether.
