60 AGROSTIS ALBA. 



Floret of two unequal-sized paleee, exterior one ovate, hairy at the 

 base, and notched at the apex; inner one only half the length, with 

 cloven apex, entire margins, and semitransparent. 



Length from eighteen to twenty-four inches. 



Flowers in the third week of July, and seeds ripen at the end of 

 August. 



This species is subject to variety. 



Dr. Parnell describes two varieties, namely: 



1st. Stolonifera. Growing on damp heavy ground near the sea, 

 and by the side of ditches and other wet situations. It has the 

 branches of the panicles densely tufted. 



2nd. Palustris. With larger spikelets, growing in damp, shady, 

 stagnant situations. 



Sir W. Hooker remarks, "In some there is a short awn at the 

 base of the outer glumella; this constitutes the Agrostis compressa of 

 Willdenow, and occasionally the flowers are viviparous, when it is the 

 A. sylvatica of Linnseus." 



The illustration is from a specimen forwarded by Mr. J. Sidebotham, 

 of Manchester.
