Potamogeton alpinus  Potamogeton alpinus is a species of aquatic
plant known by the common names alpine pondweed and red
pondweed. It is native to much of the Northern Hemisphere,
including Eurasia, Greenland, Canada, and northern parts of the
United States. It grows in water bodies such as ponds, lakes,
marshes, and slow-moving streams. This is a perennial herb
anchoring in the mud substrate via rhizome. It produces a
cylindrical stem, sometimes with branches, approaching two
meters in maximum length. It has lance-shaped leaves up to 8 cm
long and 2 wide. The plant can be distinguished from other
pondweeds by the red colour of its herbage.[1] The inflorescence
is a spike of flowers a few centimeters long rising above the
water surface.     Source: Wikipedia  Belongs to 1 community
