''Lespedeza cuneata'' is a species of flowering plant in the legume family known by the common names Chinese bushclover and sericea lespedeza, or just sericea.〔Gucker, Corey. (2010) (Revised from Munger, Gregory T., 2004). (''Lespedeza cuneata'' ). In: Fire Effects Information System, (). U.S. Department of Agriculture, Forest Service, Rocky Mountain Research Station, Fire Sciences Laboratory. Retrieved 11-26-2011.〕 It is native to Asia and eastern Australia〔(''Lespedeza cuneata''. ) Germplasm Resources Information Network. Retrieved 11-26-2011.〕 and it is present elsewhere as an introduced species and sometimes an invasive plant.〔 This plant is a perennial herb with branching stems reaching a maximum height around two meters. It grows from a woody taproot which may exceed one meter in length and which is topped with a woody caudex. The stems are covered densely in leaves, which are each divided into leaflets up to long. Flowers occur singly or in clusters of up to three in the leaf axils. Some of the flowers are cleistogamous, remaining closed and self-pollinating.〔 The open flowers are purple, cream, white, or yellowish in color.〔(''Lespedeza cuneata''. ) Global Invasive Species Database. Retrieved 11-26-2011.〕 The fruit is a legume pod containing one seed.〔 This plant has been introduced to the United States, South Africa, Brazil, Canada, and Mexico.〔 It was first planted in the US in North Carolina in 1896. It was used to control erosion and to revegetate abandoned mine sites and was used as forage for livestock. It was useful in areas susceptible to drought because its deep roots can keep it alive. A number of cultivars have been developed, including "Arlington", "Serala", and "Interstate".〔 The plant is considered invasive in many areas. When it invades a habitat it reduces the abundance and diversity of native plants and can make the area less attractive to wildlife. It may inhibit the growth of tree seedlings. It may be allelopathic, producing substances that chemically inhibit the growth of other plants.〔 Possible biological pest control agents include the Lespedeza webworm (''Tetralopha scortealis''). It will probably not be approved for use, however, because it does not discriminate between native and invasive Lespedezas. Grazing may also be a way to control the plant, especially by goats.〔 == Noxious Weeds laws == 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「Lespedeza cuneata」の詳細全文を読む スポンサード リンク
