ROEMERIA 
This laciniate form was recorded by Dillenius (loc. cit.) for Surrey : it still occurs rarely as a garden-escape, 
as in Herefordshire. 
C. majus is not uncommon in hedgerows, roadsides, and waste places, chiefly near cottage-gardens ; north- 
wards to Inverness-shire, and widespread in Ireland.
