 gi-anular. Size about 31yu. Separated-grains, size 1 to 4 and 5^; the smaller ones rounded, 

 the larger ones polyhedral with a central cavity. 



Festuca abyssinica Hochst. {Graminacece.) Dry endosperm. Compound grains rounded, oval, 

 elliptical, conical, frequently somewhat angular as result of pressure. Size about 17yu. Sep- 

 arated-grains rounded-angular or polyhedral; size 1.5 to 4ju. Simple grains (or separated- 

 grains which as result of continued growth have become rounded off) ; rounded or oval are 

 also present. Size about 5yu.
