Comments

provided by eFloras
Persicaria longiseta is morphologically similar to another Asian species, P. posumbu (Buchanan-Hamilton ex D. Don) H. Gross (= P. caespitosa). Its spread in the United States since its introduction near Philadelphia in 1910 was summarized by A. K. Paterson (2000).

Persicaria longiseta

provided by 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]

イヌタデ(犬蓼、学名: Persicaria longiseta)は、タデ科イヌタデ属一年草道端に普通に見られる雑草である。

和名ヤナギタデに対し、辛味がなくて役に立たないという意味で「イヌタデ」と名付けられた[2]。赤い小さな果実赤飯に見立て、別名アカノマンマともよばれる[3]

形態・生態[編集]

アジアの温帯から熱帯に分布し、日本では北海道から、本州四国九州沖縄に分布する[3]。野原や道端、畑などにふつうに生える[2][3]

の基部は横に這い、まっすぐか斜めに傾いて伸び、多く枝分かれして草むらのようになって小さな集団を作る。茎の先はやや立ち、高さは20 - 40cm。茎は円柱形で柔らかくなめらかで、ふつう紅紫色を帯びる[3]

葉は互生で、披針形(ひしんけい)で葉の両端がとがり、葉先に向かってだんだん細くなる。葉縁や裏側の葉脈上に毛が生える[3]。葉がつく茎の周囲には、長さ約8mmの筒状のさやである托葉梢(たくようしょう)があり、さやの縁に緑毛が生える[2]。同じ科のオオイヌタデには葉の根元のさやに毛が生えておらず、見分けることができる[3]

からまでの4月 - 11月にかけて、茎の先端から長さ1 - 5cmの花穂を出し、紅紫色をした小さな花を密につけ、まれに白い花が見られることもある[2][3]。紅紫色の萼片は深く4または5裂し、裂片は倒卵形をしており、花弁はない[2][3]雄しべは8本、花柱は3本ある[3]

花よりも、その後に見られる真っ赤な果実が目立つ。果実は三角状の痩果(そうか)で[3]、果実そのものは卵形で暗褐色をしているが、その外側に赤いをかぶっているので、このように見えるものである[2]

人間との関わり[編集]

雑草ではあるが、非常に美しく、画材などとして使われることもある。

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.
