Frequent in hill burns and bog pools

Flowers c 6-8 mm long.  Bladders c 1.5-2 mm across.

ID: Leaves divided fanwise into linear segments without teeth or bristles.  This and the presence of bladders identifies the species.

Other features: Does not always flower, and other bladderworts are even less likely to be found in flower, so identification must be based on the leaves which are usually underwater but sometimes exposed after dry weather.  Some of the stems have colourless bladders only, others have both leaves and bladders.  The bladders are for trapping small creatures on which the plant feeds.
