What is Potamogeton distinctus

Potamogeton distinctus or Hirumishiro (scientific name: Potamogeton distinctus) is a perennial floating-leaved water plant native to Japan, the Korean Peninsula, and China, belonging to the family Potamogetonaceae. It grows in shallow water in lakes, rivers, and irrigation channels in Hokkaido, Honshu, Shikoku, and Kyushu. It produces white thread-like roots, submerged stems, and leaves from nodes on underground stems, and reproduces by crawling horizontally in the mud on sandy bottoms. The oval leaves float on the surface of the water, and the inflorescences emerge from the axils of the leaves to the surface. The name comes from the fact that it grows in clusters in areas teeming with blood-sucking leeches. It is now extinct due to the widespread use of herbicides.
