Sporobolus virginicus
(

)
fornecido por wikipedia EN
Sporobolus virginicus, known by numerous common names including seashore dropseed,[2] marine couch, sand couch, salt couch grass, saltwater couch, coastal rat-tail grass, and nioaka, is a species of grass with a wide distribution.
Description
It is a spreading perennial tussock grass from 10 to 50 cm (3.9 to 19.7 in) in height. Its flowers are green or purple. It reproduces asexually by use of both stolons and rhizomes.[3]
Taxonomy
It was originally published by Carl Linnaeus in 1753, under the name Agrostis virginicus. It was transferred into Sporobolus by Karl Sigismund Kunth in 1829. It has a great many synonyms.[4]
Distribution and habitat
It grows in Australia, New Zealand, many Pacific Islands, the Caribbean, Africa, India, China and Indonesia. It is widespread in Australia,[5] occurring in every state, although in New South Wales it is considered naturalised.[6]

Sporobolus virginicus
(

fornecido por wikipedia FR
Sporobolus virginicus, la sporobole de Virginie, est une espèce de plantes monocotylédones de la famille des Poaceae, sous-famille des Chloridoideae, à répartition pantropicale. Ce sont des plantes herbacées vivaces, cespiteuses, rhizomateuses, aux tiges dressées ou décombantes de 15 à 30 cm de haut. C'est une espèce adaptée aux dunes côtières, en particulier sous le niveau de la marée haute, qui tolère un niveau de salinité important. On l'utilise pour stabiliser les dunes sur les rivages soumis à l'érosion éolienne.
