In moist meadows, and fields inundated in autumn. /3 in ditches 

 and wet situations, on a clay soil, especially near the sea. y 

 in woods. 



Perennial. July, August. 



A larger plant than A. vulgaris, from which it essentially and mani- 

 festly differs, in having an elongated, ribbed, bluntish, mostly 

 downy, finally torn, stipula ; whereas that of vulgaris is scarcely 

 visible at all, or at most not a line in length. I concur with 

 Professor Hooker and Mr. Bicheno in uniting A. stolonifera to 

 alba, but by no means in perceiving any ambiguity between the 

 latter and vulgaris. 



A. alba has long, decumbent, more or less branching, stems, send- 

 ing out roots from tlieir lower joints. The leaves are broad, flat.
