 obtuse, scarious-margined, not at all keeled, or scarcely 

 so in fruit, herbaceous, nearly covering the utricle; 

 seed horizontal, readily separating from the pericarp, 

 black, shining; embryo completely annular.

 narrowed at the base, slender-petioled, i r -4? long 

 and nearly as wide, the uppermost sometimes very 

 small, oblong or lanceolate and acute; spikes slen- 

 der, axillary to the upper leaves and in terminal 

 panicles; calyx y z ff wide, its segments keeled in
