It is endemic to Santa Cruz County, California,〔(Calflora taxon report, University of California, ''Polygonum hickmanii'', H.R. Hinds & R. Morgan, Hickman's knotweed )〕 where it is known from only two sites in the Scotts Valley. It grows on coastal prairie on mudstone and sandstone substrates, in an area known for its spring wildflowers. The small plant was first noted in 1990 and described as a new species in 1995.〔(Hinds, H.R. and R.Morgan. (1995). ''Polygonum hickmanii'' (Polygonaceae), a new species from California. ''Novon'' 5:4 336. )〕〔(Local Species Profile )〕 The plant is a federally listed endangered species. ''Polygonum hickmanii'' is a small annual plant forming compact patches on the ground, its stem growing no more than about 5 centimeters (2 inches) tall. It is lined with linear leaves especially near the tips of the branches, and has a cylindrical, shreddy ochrea. Solitary flowers occur in the leaf axils. They are only 2 or 3 millimeters long and white or pink-tinged in color. The eight tiny stamens are tipped with orange-pink anthers.〔(Flora of North America, ''Polygonum hickmanii'' H. R. Hinds & Rand. Morgan, 1995. Hickman's knotweed )〕 Threats to ''Polygonum hickmanii'' include proposed development in its small, patchy habitat and the invasion of non-native plants.〔(The Nature Conservancy )〕 ==References== 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「Polygonum hickmanii」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
