veined, the lower 2’-3’ long, 13’-2’ wide; spikes rather 
thick, dense, stout, obtuse, 2’-3’ long in fruit; bracts 
lanceolate, shorter than the flowers; calyx-teeth seta- 
ceous, one-half as long as the campanulate tube, or 
more; corolla pubescent.

in the upper axils; spikes seldom more than 1’ long 
in fruit; bracts lanceolate, shorter than the flowers;
