The glumes tend to be subequal, but according to the 

 Brunoiau rule of obliteration, the outer ought to be the smal- 

 ler. These one flowered grasses are worthy of study, for the 

 palae are always smaller than the glumes, and always more or 

 less membranous, whereas the outer, in the many-flowered 

 genera is always glumoid, the glumes are of nearly equal in- 

 sertion, it hence is necessary to study the situation of the sta- 

 mina, in order to determine the position of the glumes, which 

 may be inferred also, from the largest palea being always 

 on the outside, and opposed to the outer glume.
