This perennial trailing or prostrate plant has many stems. Its few small, pale yellow five-petalled flowers (8-10mm) are borne in small leafy cymes. It flowers from June to September. The sepals have black-dotted margins and the small, oblong, paired leaves have black and translucent dots. Not quite as widespread as some other St John's-worts, this plant grows on bare, sometimes sandy, ground with acid soil. It is a native plant belonging to the family Hypericaceae.
I first identified this plant in Laragh in 1977 and photographed it in Tullycanna, Co Wexford in 2007.
