 Templeton noted this plant as occurring in ditches by Lough Neagh, 

 but there is reason for thinking that he was mistaken. Similar stations 

 were assigned by Whitla, and Moore, but it is probable that C. hamulata, 

 which they do not mention, was the plant really seen in the Portiuore 

 ditches, and not C autuin.nalis, which is a denizen of clear water.
