About the species

Identification

50–100 cm tall. Stem hollow, ridged, branched and almost hairless, without leaf-like flanges along the ridges. Leaves are triangular and very finely divided several times into narrow, smooth-edged strips; the tips of the strips are often darker. Flower heads are many flat-topped clusters of small white flowers, with narrow, drooping leaf‑like pieces hanging beneath each cluster. Seeds are 4–5 mm, oval, brown, flattened from the side, with a broad rim along the edges. Look for the very narrow leaf strips and broad‑rimmed seeds. Flowers in Finland in July–August.
