Bladderwort agg. - Utricularia vulgaris agg.

Description

According to the BSBI, Greater Bladderwort (Utricularia vulgaris) can only be distinguished from Bladderwort (Utricularia australis) reliably when flowers are present, so for records where this is not the case we have decided to treat the two as an aggregate. Examination of a specimen is likely to be needed for accurate identification. The plants are free floating with much branched green leaves that have bladders on.

Identification difficulty
Habitat

When to see it

Life History

Insectivorous perennial.

UK Status

Widespread but not particularly common in Britain.

VC55 Status
