Wood Cranesbill (Geranium sylvaticum)
Inverness-shire, Scotland, 2004

The small perennial wood cranesbill has an unusual reproductive strategy, gynodioecy. Each individual plant is either a female or a hermaphrodite. This was of great interest to Charles Darwin, who published "The different forms of flowers on plants of the same species" in 1888.

Wood cranesbill can not tolerate hot dry summers, and it may vanish from southern parts of Britain as global warming accelerates.
