''Carex fracta'' is a species of sedge known by the common name fragile sheath sedge. It is native to the western United States from Washington to California, where it grows in moist to dry areas in mountain forests and meadows. This sedge produces dense clumps of stems sometimes exceeding a meter tall. The leaves are attached to the stem with a characteristic thin, membranous sheath. The inflorescence is a dense or loose cluster of light green to gold spikes. Some spikes occur lower on the stem as well. The flowers are covered in light colored scales. ==External links== *(Jepson Manual Treatment ) *(USDA Plants Profile ) *(Flora of North America ) *(Photo gallery ) 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「Carex fracta」の詳細全文を読む スポンサード リンク
