Mureș Floodplain Natural Park
The Mureș Floodplain Natural Park, set aside by the Romanian government in 2005, is located in western Romania outside the city of Arad. The park covers 17,455 ha and follows the river Mureș westward from the city of Arad to the Hungarian border. The park is a typical ecosystem for wetlands, with running waters, lakes, swamps and floodplains, with forests, an important place for the passage and nesting of bird species and is subjected to periodical floods (a flood every three years). The forests (7,500 ha) in the park are made up primarily of common oak, narrow-leafed ash, black and white poplar, white willow, and American black walnut. This area is an important place for nesting and passage for nearly 200 species of birds, most of which are strictly protected internationally. The main purpose of the Mureș Floodplain Natural Park is to protect and preserve the habitats and landscape diversity from the region. The park has been designated a Ramsar site, and under Natura 2000, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Water Soldier
''Stratiotes'' is a genus of submerged aquatic plant commonly known as water soldiers, described as a genus by Linnaeus in 1753. Several specific names have been coined within the genus, but at present only one is recognized: ''Stratiotes aloides''. native to Europe and NW Asia. ;formerly included in genus moved to other genera: ''Enhalus Hydrocleys Ottelia'' # ''Stratiotes acoroides - Enhalus acoroides'' # ''Stratiotes alismoides - Ottelia alismoides'' # ''Stratiotes nymphoides - Hydrocleys nymphoides'' # ''Stratiotes quinquealatus - Ottelia alismoides'' Description The leaves are serrate and very brittle, breaking easily when handled. Reproduction is generally by offsets, which may number five or more per plant. In the UK, male plants have rarely if ever been recorded, although some hermaphrodite flowers have been recorded from more southerly locations. Sexual reproduction is not known to occur. A characteristic of the genus is the habit of the plants rising t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Trapa Natans
The water caltrop is any of three extant species of the genus ''Trapa'': ''Trapa natans'', ''Trapa bicornis'' and the endangered ''Trapa rossica''. It is also known as buffalo nut, bat nut, devil pod, ling gok (Chinese: 菱角), ling nut, lin kok, ling jow, ling kio nut, mustache nut, singhara or water chestnut. The species are floating annual aquatic plants, growing in slow-moving freshwater up to deep, native to warm temperate parts of Eurasia and Africa. They bear ornately shaped fruits, which in the case of ''T. bicornis'' resemble the head of a bull or the silhouette of a flying bat. Each fruit contains a single very large, starchy seed. ''T. natans'' and ''T. bicornis'' have been cultivated in China and the Indian subcontinent for the edible seeds for at least 3,000 years.

Salvinia Natans
''Salvinia natans'' (commonly known as floating fern, floating watermoss, floating moss, or commercially, water butterfly wings) is an annual floating aquatic fern, which can appear superficially similar to moss. It is found throughout the world where there is plentiful standing fresh water, sunlight, and humid air, but is especially common in Africa, Asia, central Europe, and South America. In New York State and Massachusetts, it is an introduced species. Characteristics ''Salvinia natans'' has two nickel-sized leaves lying flat against the surface of the water, and a third submerged leaf which functions as a root. Flotation is made possible by pouches of air within the leaves. Cuticular papillae on the leaves' surface keep water from interfering with the leaves' functioning, and serve to protect them from decay. Spore cases form at the plant's base for reproduction. The leaves of ''S. natans'' block sunlight from reaching very far underwater. This is helpful to many freshwat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Platanthera Bifolia
''Platanthera bifolia'', commonly known as the lesser butterfly-orchid, is a species of orchid in the genus ''Platanthera'', having certain relations with the genus ''Orchis'', where it was previously included and also with the genus ''Habenaria''. It is a Palaearctic species occurring from Ireland in the west, across Europe and Asia to Korea and Japan. It is also found in North Africa. The name ''Platanthera'' is derived from Greek, meaning "broad anthers", while the species name, ''bifolia'', means "two leaves". Identification Lesser butterfly-orchids are not to be confused with the greater butterfly-orchid, which are about the same size. Lesser butterfly-orchids are distinguished by their two shining green basal leaves, especially of the hill form, which are shorter and broader and by the angle of the pollinia. The upper sepal and petals form a loose triangular hood above the pollinia, which lie parallel and close together, obscuring the opening into the spur, which is lon ...
