The botanical characters of this grass are almost 



the same as those of the Avena eliator , differing in the 



want of the awns only. It has the essential character 



of the Hold (Florets male, and hermaphrodite. Calyx 



husks two-valved with two florets) and since the 



Avena eliator is now referred to that genus this may 



with certainty be considered a variety of it.
