Not uncommon in Argyll but rare further north.  In bare ground at edges of tracks.

Flower diameter c 8-12 mm

ID: Told from other St John's Worts by petals being hardly longer than sepals.  Easily told as a St John's Wort by the large number of stamens and the translucent glands visible when leaf held up to the light.

Other features: Stem very thin, with 2 raised lines.  Leaves and petals often with black dots around the margin on the underside.  Plant hairless, trailing along the ground.
