 is often cultivated as Iv'attlesnukc-CJrass for the sake of its large showy spikelets.

A genus of about V2f> si)ecies, wliich have been arranged under several dilferent genera ; natives 

 of arctic, cold and temperate countries, some of them of value in agriculture. It inrludes bulh 

 annuals and perennials, of which the lloweis and often the leaves are rather harsh and dry.
