 about 2 dm. long, closely sheathing, the petiole proper 1.5 cm. 

 long, stout. Blade 1.5 dm. long, suborbicular or broader than 

 long. Culm above the leaf bearing one or more aphyllous 

 sheaths at the base of peduncles which develop later than the 

 terminal one, these sheaths more than 1 dm. long, herbaceous, 

 acute. Pedimcles about 2 dm. long, slender, about as long as the 

 spike, which is compressed. Scales imbricate, 2 cm. long, the
