The term glabra is only proper when applied to the upper part of this plant, the radical leaves, which generally 

 decay as the plant approaches to maturity, being hairy, like many other plants of the fame family. 



It is found but rarely near London. Hitherto I have only noticed it in one fpot, viz. in the lane which leads down 

 by Charlton Church, and there but fparingly ; further on in Kent it is much more common, as well as in many other 

 parts of England. It ufually grows on banks near hedges, and flowers in June and July. 



It varies fo much in fize, that the oid Botauifts make two fpecies' of it.
