Polygonaceae

The Polygonaceae are a family of flowering plants known informally as the knotweed family or smartweed—buckwheat family in the United States. The name is based on the genus Polygonum, and was first used by Antoine Laurent de Jussieu in 1789 in his book, Genera Plantarum. The name may refer to the many swollen nodes the stems of some species have, being derived from Greek ( meaning and meaning or ). Alternatively, it may have a different origin, meaning 'many seeds'.

AI overview

The Polygonaceae family, informally known as the knotweed or smartweed family, is a group of flowering plants whose name likely refers to either the swollen nodes found on some species' stems or to their production of many seeds. This family has been formally recognized since 1789, when botanist Antoine Laurent de Jussieu first named it based on the genus Polygonum.

蓼科海葡萄屬的海葡萄蓼科（Polygonaceae），是一種多年生挺水植物種類，高從40公分到160公分以上都有。葉子通常呈現兩兩互生及長針狀，有柄。花朵則通常長成穗狀。一般來說，該種植物都生長在水田，人造溝渠或溼地。蓼科約有50屬，1120種。本科植物主要分佈於溫帶地區，有少數種類分佈於熱帶地區，中国有12属约200余种。植株為草本、灌木或小喬木。花雌雄同株或雌雄異株。在克朗奎斯特系統裡为蓼科单独设立一个蓼目。而最近的APG II系統（2003年）則是將蓼科處理為石竹目下的一個科。

The Polygonaceae comprise about 1200 species distributed into about 48 genera. The largest genera are Eriogonum (240 species), Rumex (200 species), Coccoloba (120 species), Persicaria (100 species) and Calligonum (80 species). The family is present worldwide, but is most diverse in the North Temperate Zone.
