 vel cylindraceis, densis, usque ad 1 cm longis, pedunculis leviter 

 capitato-glandulosis. 



A slender, ascending, simple or very sparingly branched plant, 

 nearly glabrous, the stems often decumbent below, 4-angled, 1

 down one side, brown, membranaceous, about 1 cm long, apex 

 truncate, the apical margin with erect, rigid, 2 to 3 mm long 

 cilia, the base of the sheath often with few reflexed, spinelike 

 cilia. Racemes few, short, dense, 1 cm long or less, oblong or 

 cylindric, very loosely corymbose, the peduncles slender, spar- 

 ingly capitate-glandular. Bracts oblong-ovate, margins and apex
