''Stephanomeria paniculata'' is a species of flowering plant in the aster family known by the common names tufted wirelettuce and stiff-branched wirelettuce. It is native to the northwestern United States, where it grows in many types of habitat, including disturbed areas. It is an annual or biennial herb producing a slender, erect stem with stiff, widely spreading branches toward the top. It is hairless. The leaves are mostly located in a basal rosette, the largest reaching 10 centimeters long. Smaller, linear leaves occur along the upper stem. Flower heads occur singly or in small clusters along the stiff branches. Each head contains 4 to 6 ray florets, each with an elongated tube and a pinkish or lavender ligule up to 1.4 centimeters long. The fruit is an achene tipped with a spreading cluster of long, white pappus bristles. ==External links== *(Jepson Manual Treatment ) *(USDA Plants Profile ) *(Flora of North America ) *(Washington Burke Museum ) *(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「Stephanomeria paniculata」の詳細全文を読む スポンサード リンク
