Frequent in lochs, slow-moving burns and bog pools.

Bladders c 2-3 mm, leaves c 4-12 mm

ID: Leaves fan-shaped with small bristles on the segments. Bladders and leaves are on separate stems, with the odd exception.

Other features: Flowers probably never produced in the area. They are similar to those of Lesser Bladderwort but have red streaks. If you ever see them get clicking with that camera!

Update: all plants I've examined from the area have turned out to be U stygia. Will describe microscopic differences here in due course; they are given in Stace.

I don't think it was really this colour but that's typical
of photographing underwater plants. In this pic you
can see the bristles on the edges of the leaf segments.
