Pete's Walks - Venus's-Looking-Glass
Photo taken 27/06/10 at College Lake, Bucks.
Venus's-looking-glass grows on arable land where the soil is calceous, mainly in the south, midlands and east of England. It flowers between May and August. Its name comes either from its shiny seeds or from its calyx (fusion of sepals) which resembles a mirror-handle.
This is a slight 'cheat' as the photo was taken at one of the meadows at the College Lake reserve where such wildflowers are deliberately planted and grown. I have not yet come across it on any of my walks.
