Salvinia (Watermoss) Ség. 1754
plant genus in the salviniaceae family
Salvinia or watermosses is a genus of free-floating aquatic ferns in the family Salviniaceae. The genus is named in honor of 17th-century Italian naturalist Anton Maria Salvini, and the generic name was first published in 1754 by French botanist Jean-François Séguier in Plantae Veronenses, a description of the plants found around Verona. Twelve species are recognized, at least three of which (S. molesta, S. herzogii, and S. minima) are believed to be hybrids in part because their sporangia are found to be empty. Salvinia is related to the other water ferns, including the mosquito fern Azolla.
Nymphoides (Floatingheart) Ség. 1754
plant genus in the menyanthaceae family
Nymphoides, or floatingheart, is a genus of aquatic flowering plants in the family Menyanthaceae. The genus name refers to their resemblance to the water lily Nymphaea. Nymphoides are aquatic plants with submerged roots and floating leaves that hold the small flowers above the water surface. Flowers are sympetalous, most often divided into five lobes (petals). The petals are either yellow or white and may be adorned with lateral wings or covered in small hairs. The inflorescence consists of either an umbellate cluster of flowers or a lax raceme, with internodes occurring between generally
Pseudorchis (Bog Orchid) Ség. 1754
plant genus in the orchidaceae family
Pseudorchis is a monotypic genus of flowering plants from the orchid family, Orchidaceae. The sole species is the small white orchid (Pseudorchis albida). It is found across much of Europe and northern Asia from Spain and Iceland to Kamchatka, including France, Great Britain, Germany, Poland, Scandinavia, Ukraine and much of Russia. It also occurs in Greenland and eastern Canada (Quebec, Newfoundland and Labrador). (Codes) Three subspecies are recognized: Pseudorchis albida subsp. albida - from Spain and Iceland to Kamchatka Pseudorchis albida subsp. straminea (Fernald) Á.Löve & D.Löve -
Scirpoides (Bulrush) Ség. 1754
plant genus in the cyperaceae family
Scirpoides is a genus of sedges (Cyperaceae), native to Europe and adjoining areas, and introduced elsewhere. It was split off from Scirpus.
Chamaenerion (Fireweeds) Ség. 1754
plant genus in the onagraceae family
Chamaenerion is a genus of flowering plants in the family Onagraceae (the evening primrose or willowherb family). It has sometimes been included in the genus Epilobium. Members of the genus may be called willowherbs (along with Epilobium), or fireweeds, based on a common name used for C. angustifolium. They are upright herbaceous perennials, growing from a woody base or from rhizomes, with racemes of usually purple to pink flowers. All species are found in the northern hemisphere. Most occur in moist habitats; C. angustifolium is the exception, favouring disturbed ground.
