Form, .Size, and Colour.âThe flowering glume is divided at its tip, the halves being pro- 'â "^ longed into two short awns. A twisted and bent awn arises at a point not quite half way down the back of the glume, the base of the latter being fringed with a few short hairs ; the rachilla bears many long white hairs upon it. The length of the seed is about 4^5 mm., of a pale-brownish straw colour. PupaTv.âThe seed is almost entirely hand- collected and is usually very imjjure. It is difficult to clean, and samples are adulterated with the ~Ozx- useless "W'avy Hair-grass {Aira f/exuosa L.) which resembles it (Fig. 214). The impurity is readily detected by its darker colour and the position of the awn very which arises near the base of the flowering glume ; the rachilla lies closer to the pale than in Golden Oat-Grass, is much shorter, and the hairs upon it not so long : the hairs at the base of the seed are, however, more prominent in the Wavy Hair-grass. The Germination Capacttv is always low as there is a difficulty in clearing away the empt)- chafif; in the be^t samples.
