Nuphar pumila Least Water-lily RR DD N
As with most genuinely wild Water Lilies these plants are tantalisingly too far away to get a decent photograph. In addition this one is famous for the flowers hardly ever opening.
However, on what turned out to be a reasonable day, we managed to see a few flowers which appeared to have just about opened. N. pumila was flourishing amongst other shallow fresh water plants such as Equisetum fluviatile (Water Horsetail) and Potamogeton natans (Broad-leaved Pondweed).
Although very occasionally recorded from England and Wales where it has probably been introduced, this plant has its home in mid (above the industrial Glasgow-Edinburgh belt) to northern Scotland. Ignoring those odd records it is only really found in Scotland.
