Persicaria longiseta
(
الإنجليزية
)
المقدمة من wikipedia EN
Persicaria longiseta is a species of flowering plant in the knotweed family known by the common names Oriental lady's thumb, bristly lady's thumb, Asiatic smartweed, long-bristled smartweed, low smartweed, Asiatic waterpepper, bristled knotweed, bunchy knotweed, and tufted knotweed. It is native to Asia (China, India, Russia, Japan, Malaysia, etc.),[2] and it is present in North America and Europe as an introduced species and often a weed.[3][4]
Persicaria longiseta is an annual herb with stems 30 to 80 centimeters (12–32 inches) long,[5] sometimes reaching one meter (40 inches).[3] The hairless, branching stems may root at lower nodes that come in contact with the substrate. The leaves are lance-shaped and up to 8 centimeters (3.2 inches) long by 3 cm (1.2 inches) wide. They have bristly ochrea. The inflorescence is an elongate cluster up to 8 centimeters (3.2 inches) long and contains many pink flowers. The fruit is a small, smooth achene.[5]
In its native region this plant is a common weed of rice paddies. It was introduced to North America near Philadelphia around 1910 and probably spread via the railroads. It is present in much of the eastern United States and much of Canada.[6] It grows in moist habitat types such as wetlands, as well as dry and upland habitat. It can be found in meadows, marshes, mudflats, riverbanks, floodplains, levees, and lowland and upland forests. It is invasive in some areas.[3]

빈터나 밭에서 흔히 자란다. 키는 20~50 센티미터 정도이다. 줄기는 털이 없고 적자색이 돈다. 밑 부분이 비스듬히 자라면서 땅에 닿으면 뿌리를 내리고 가지가 뻗어 곧게 자라 줄기가 여럿 모여 난 것처럼 보인다. 잎은 어긋나고 가장자리가 밋밋하다. 넓은 피침형 또는 피침형인데 양끝이 뾰족하고 길이 3~8 센티미터, 너비 1~2.5 센티미터쯤 된다. 꽃은 6~9월에 피며 줄기나 가지 끝에 조그만 꽃이 이삭 모양의 꽃차례에 촘촘히 모여 달린다. 열매는 수과로 흑갈색이며 달걀 모양에 세모지며 꽃받침에 싸여 있다.
