64 AGKOSTIS SPICA-VENTI. 



Calyx consisting of two unequal acute glumes, with rough keels, 

 the uppermost one largest. Floret of two palese, exterior one 

 ovate-lanceolate, roughish, and bearing a tuft of hairs at the 

 base. Awn long, rough, slender; proceeding from slightly below 

 the summit of the palea, and being above three times its length. 

 Inner palea shorter. Apex bifid. Margins entire, membranous, 

 and linear. Seeds exceedingly smooth. 



Flowers in June and July. 



This Grass is readily recognised by the great length of the 

 awn, in comparison with that of the floret. 



For specimens I am indebted to Mr. Joseph Sidebotham, of 

 Manchester. 



The illustration is from a specimen procured at Godalming, 

 in the county of Surrey, by Mr. J. D. Salmon.
