A perennial plant of the Utricularia family (APG classification: Utricularia family). The leaves are basal, 3-5 cm long, ovate-oblong, with inward-curling edges, and densely covered with short glandular hairs that secrete mucus. In July and August, a single purple lip-shaped flower opens sideways at the end of a 5-15 cm tall flower stalk. Known as a carnivorous plant, when a small animal touches the surface of the leaves, the leaves close, engulfing the animal, dissolving it in the mucus, and digesting it. It grows on damp rock walls and grasslands from mountainous to alpine areas, and is widely distributed in Shikoku, Honshu north of the Chubu region, and from Hokkaido to the Circumpolar Arctic. The name comes from the fact that the flowers resemble violets, and it is a carnivorous plant. The genus Viola has entire leaves that grow in a rosette shape at the base. There are about 80 species in the world, and this species and the Red Viola are found in Japan. [Hideo Takahashi October 20, 2021] [Reference item] |A carnivorous plant of the Utricularia family.

タヌキモ科(APG分類:タヌキモ科)の多年草。葉は根生し、長さ3~5センチメートル、卵状長楕円(ちょうだえん)形で縁(へり)は内側に巻き、表面に粘液を分泌する短い腺毛(せんもう)を密布する。7~8月、高さ5~15センチメートルの花茎の先に、紫色の唇形花を1個横向きに開く。食虫植物として知られ、葉の表面に小動物が触れると閉じて小動物を巻き込み、粘液で溶かし、消化する。山地から高山の湿った岩壁や草原に生え、四国、中部地方以北の本州、北海道から周北極地方に広く分布する。名は、花がスミレに似ており、食虫植物であることによる。 ムシトリスミレ属は葉は全縁でロゼット状に根生する。世界に約80種、日本には本種とコウシンソウが分布する。 [高橋秀男 2021年10月20日] [参照項目] |タヌキモ科の食虫植物。葉は卵状長楕円形で縁は内側に巻き、表面に粘液を分泌する短い腺毛がある。7~8月、花茎の先に紫色の唇形花を1個横向きに開く©Shogakukan 撮影/青山富士夫"> ムシトリスミレ 出典 小学館 日本大百科全書(ニッポニカ)日本大百科全書(ニッポニカ)について 情報 | 凡例 |
