There's an interesting article in the most recent British Wildlife magazine (June 2012) about duckweed. Often overlooked or targeted by wetland managers for its invasive tendencies duckweed species are some of the most successful  water plants in the British Isles. Having resurrected my interest in the ecological value of the Mon and Brecon Canal last Saturdays stroll between Cwmbran and Newport turned in a good variety of floating vegetation. The above photos are just a sample of what was on offer.
