their length without the awn varies from 6-10 mm. The outer 

 palea of the lower flower bears a long (10 mm. or more) twisted 

 and "kneed" dorsal awn. The outer palea of the upper flower 

 usually bears only a short sub- terminal awn-point, but it may 

 have a dorsal, twisted and "kneed" awn; its apex is ragged. 

 Both of the outer palese are distinctly nerved, and the margins of 

 both inner paleae are delicately fringed. Each flower has a con- 

 spicuous basal tuft of white hairs. (Fig. 55.) 



(N.B. The twisting of the awns is only apparent when the 

 seed is ripe.)
