284 DIFFERENTIATION AND SPECIFICITY OF STARCHES. 



Festuca sluartina Steud. (Graminacecc.) Dry endosperm. — Compound grains round, oval, pyriform, 

 friq\icntly somewhat angular as result of pressure, reticulated. Hize about 15^. Separated- 

 grains, size 1.5 to 5^; the smaller ones rounded-angadar, the larger ones polyhech-al, and have 

 a cavity. Simple grains are also observed which are rounded, oval, or pyriform; the larger 

 ones hollow. Size 6 to 7ai.

Festuca dumetorum Linn; Festuca rubra var. Linn. {Graminacece.) Dry endosperm. — Compound 

 grains usually oval or elliptical, frequently somewhat angular, granular or reticulated- 

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

 the larger ones polyhedral with a central cavity. 



Festuca abyssinica Hochst. (firaminaceoe.) Dry endosperm.- — Compound grains rounded, oval, 

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

 arated-grains rounded-angidar or polyhedral; size 1.5 to 4^4. Simple grains (or separated- 

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

 also present. Size about 5^1.

 pound grains spherical or oval, homogeneous or granular. Size about 16/*. Separated-grains 

 rounded to polyhedral; size 1 to 4^. 



Festuca glauca Lam. ; Festuca ovina var. (Graminacece.) Dry endosperm. — Compound grains spherical, 

 oval, or conical; half to as thick as long, homogeneous or granular, consisting of 20 to over 

 8000 components. Size about 18/i, rarely 25jw. Sepai-ated-grains rounded to polyhedral.

 tical, angular through pressm-e, reticulated or granular. Size about 15 to 20ju. Separated- 

 grains, size 1 to 3.5ju; the small ones rounded, the larger ones polyhedral.
