Spiranthes cernua (L.) Rich. op het terrein „De Wolf” te Haren, Gr

A few specimens of Spiranthes cernua (L.) Rich., a native of Canada and the United States, were found in a wild state in the Botanical Garden “De Wolf” at Haren, prov. Groningen, in 1961 and 1962. As S. cernua was never cultivated there, and unintentional introduction by men is rather unlikely, the authors suppose that seeds of the species, which is sometimes cultivated in aquaria and terraria, may have found their way to the garden.
