 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. SpiJeelets ^ by

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

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