(Cardamine flexuosa)
Cardamine flexuosa, commonly known as wavy bittercress or wood bitter-cress, is an herbaceous annual, biennial, or short-lived perennial plant in the cabbage family (Brassicaceae). This is a small flowering plant growing to a height of no more than 30 cm, usually perennial, with few short, erect stems. The leaves pinnate, mostly at the base, each with about 5 pairs of rounded leaflets. Flowers very small, white, 3 – 4 mm across with 6 stamens. Fruits generally not overtopping the flowers - a feature distinguishing it from Cardamine hirsuta. Common throughout the British Isles and Europe. In Ireland common in woods shady and damp places.
