Fool's-water-cress - Apium nodiflorum
Low to medium, prostrate to ascending plant, the stems finely grooved, rooting at the lower nodes. Leaves 1 pinnate, with 5 to 13 oval or lanceolate, toothed segments. Flowers white and minute, the umbels leaf opposed, short stalked or unstalked, with 3 to 12 rays. No bracts, but with bracteoles.
Very similar to Lesser Water-parsnip when it isn't in flower, and often confused with it. Sometimes mistaken for watercress.
No bracts, but bracteoles; flowers in leaf axils, not terminal. Unlike Berula erecta, lacks a white ring-mark/ridge around the lower leaf petioles.
