Apium inundatum
(Map updated: March 2008)
 

An aquatic species submerged in shallow water in lakes, or growing on muddy lakeshores. The leaves are finely divided into linear segments, rather like those of the water crowfoots (Ranunculus spp.). Generally a low-growing plant with the stems lying more or less horizontal, sometimes rooting at the nodes. The flowers are small with white petals, arranged in very small umbels held up above the water.

All names: Apium inundatum (L.) H.G.Reichb.
