Soft rush or common rush (''Juncus effusus'') is a perennial, herbaceous flowering plant species in the family Juncaceae. It is nearly cosmopolitan, considered native in Europe, Asia, Africa, North America, and South America, and naturalized in Australia, Madagascar, and various oceanic islands.〔(Kew World Checklist of Selected Plant Families )〕〔Kirschner, J. & al.

Pl. 1: 326. 1753 )〕〔(Flora of North America vol 22, Soft rush, ''Juncus effusus'' Linnaeus, Sp. Pl. 1: 326. 1753. )〕 It is found growing in wet areas, such as the purple moor-grass and rush pastures and fen-meadow plant associations in the United Kingdom. ==Description== It grows in large clumps about tall at the water's edge along streams and ditches, but can be invasive anywhere with moist soil. It is commonly found growing in humus-rich areas like marshes, ditches, fens, and beaver dams. The stems are smooth cylinders with light pith filling. The yellowish inflorescence appears to emerge from one side of the stem about from the top. In fact the stem ends there; the top part is the bract, that continues with only a slight colour-band marking it from the stem. The lower leaves are reduced to a brown sheath at the bottom of the stem. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Juncus effusus」の詳細全文を読む スポンサード リンク
