genus. The scales in this form do not become so plump as in the 

 typical form, the var. hispida and F. simplex, and in mature speci- 

 mens it is frequently necessary to use a compound microscope to 

 see the scabrosity of their upper margins. 



I have never had any difficulty in deciding whether a speci- 

 men went into var. hispida or var breviseta, the distinctive char- 

 acters, although slight, being clearly defined and constant. Never- 

 theless these differences seem too inconsequential for the basis of 

 a separate species, and although intermediate forms have not been 

 seen, they may be expected.

FUTRFNA SQUARROSA, var. HISPIDA (Ell.), Chapm. 



Stipe a little shorter than the achenium. 



Bristles reaching 



about the middle or apex of the achenium, retrorsely barbed down 



the inner face. Scale-stalks reaching the middle of the achenium. 



Scales rhomboidal, or deltoid-ovate with cordate or truncate 



base, tapering into a short thick unbarbed awn or point, usually 



minutely scabrous along the upper margin and about the base'bf 

 the awn.
