 ovoid or sub-globose, devoid of distinct groove, 

 and distending the awnless palesB, or falling

A. Glumes cuspidate, " fruit " yellowish. 



Phleum pratense. 



The student should familiarise himself with the "seed" 

 of Phleum pratense, as a type, and an important grass 

 easily obtained pure, but sometimes with minute round 

 seeds of weeds intermixed. 



Phleum pratense, L. (Fig. 45). 



Palea 2'3 mm. long, five-ribbed, with a short point, 

 delicate but hard, smooth, with a silvery lustre. Inner 

 pale two-nerved. Closely investing the yellow-brown 



' This term does not necessarily imply any botanical relationship 

 with the true Millets {Panieum), but merely that the caryopsis is short 

 and broad as in these grasses.
