rium, referred to in English Flora, &c. Near Luton, in 

 Bedfordshire, by a specimen sent to the Botanical Society 

 of London, by Miss S. Forster. In the neighbourhood of 

 Bristol, on the Gloucestershire side, according to a Cata- 

 logue of Bristol plants from Dr. J. D. Hooker, checked off 

 with the assistance of Mr. Thwaites ; but this may be an 

 error, as indicated by an explanation given under Campa- 

 nula latifolia. In a lane near Shrawley, in Worcestershire, 

 according to the Rev. G. H. Piercy, in the Midland Flora. 

 A troublesome weed in several places near Nottingham, by 

 the Flora of Notts. Two localities are mentioned in the 

 Flora of Yorkshire. And it has been reported on various 

 authority from Edinburgh, Fife, Perth, and Forfar ; though 

 the two latter counties are not quite satisfactorily shown to 

 produce it in a native condition. I suppress some other 

 localities, still unpubhshed, because they are most likely 

 erroneous, and it seems not advisable to add to the number 

 of probable errors, already in print, respecting the habitats 

 of this species.
