ENGLISH BOTANY. 
In chalky and sandy fields, ^"ery local. Bartlow Hills, Essex; 
Mildenhall and Kentford, Suffolk; Hardingham, Mundford, Beach- 
anwell, Narborough, and Martham, Norfolk; Hildersham (close by 
tlie Essex station), Cambridgeshire, and formerly in several other 
stations in the same county; Hertfordshire. I have a specimen said 
to be collected in a chalk-pit near Rochester, Kent, by Mr. Wilham 
Mclvor in 184G : it is an extremely luxuriant one, leading one to 
suspect that the example is a cultivated one.
