''Leontodon taraxacoides'' is a species of hawkbit known by the common name lesser hawkbit, rough hawkbit, or hairy hawkbit. It is native to Europe and North Africa but it can be found in many other places across the globe as an introduced species and often a noxious weed. This is a dandelion-like herb growing patches of many erect, leafless stems from a basal rosette of leaves. The leaves are 2 to 15 centimeters long, 0.5 to 2.5 centimeters wide, entire or lobed, and green in color. Atop the stems are solitary flower heads which are ligulate, containing layered rings of ray florets with no disc florets. The florets are yellow with toothed tips. The fruit is a cylindrical achene with a pappus of scales. Fruits near the center of the flower head are rough, while those growing along the edges of the head are smooth. ==External links== *(Jepson Manual Treatment ) *(USDA Plants Profile ) *(Photo gallery ) *(Skye Flora ) *(Encyclopedia of Life ) *(Flora of North America ) 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「Leontodon taraxacoides」の詳細全文を読む スポンサード リンク
