Strongly calcicole. A characteristic plant of the Central Plain. I 

 omit the Cylele, ed. I., records for Wicklow, Dublin, Antrim^and Derry . 

 The plant has not been refound in any of these well-worked counties, 

 and such habitats as " common in ditches on the bogs among the Dublin 

 mountains " are quite inapplicable to the present species, which is low- 

 land and calcicole, but would well fit some form of P. polygonifolius, 

 to which, I believe, these records should be referred.
