A perennial of seasonally or permanently waterlogged habitats on acidic to base-rich substrates. It is found in a wide range of mires, wet heaths, upland flushes and springs; also in rush-pastures, wet meadows, flushed grassland on hill-slopes and, rarely, in wet woodland rides. 0-1005 m (Macgillycuddy`s Reeks, S. Kerry).
C. echinata, which was mapped as `all records` in the 1962 Atlas, was lost from many lowland squares in England in the 19th century. Since then, and since 1962, there have been further losses through drainage and agricultural improvements. The distribution is stable elsewhere.
European Boreo-temperate element; also in N. America.
