 three-nerved, often thinner, boat-shaped. Glume iii 

 very thin and papery with a minute palea at its base.

 with two distinct styles and feathery stigmas. Grain 

 included in the outer glumes.

The third glume is so thin that it may well be mistaken for a palea, and 

 the palea that belongs to it is difficult to make out because closely appressed 

 to it and very small. See figure.
