Stuckenia pectinata (L.) Börner

Stuckenia pectinata (Potamogeton pectinatus) is a perennial, submersed, plant. It inhabits the fresh or brackish waters of ponds, lakes, spring-fed rivers, slow-flowing marshes, and streams across the majority of the globe. Indeed, it has a cosmopolitan distribution, except for the polar regions and Pacific islands.

This plant is very slender and branched, and it grows from a creeping rhizome. The multiple long, branched stems of this species often form masses at the water surface; they are slender and flexible, and they are usually several feet long. The stems may be green, brown, or reddish. Its leaves are very narrow and usually several inches long, with pointed tips. Stuckenia pectinata blooms from spring to fall; its flowers are on spikes, very tiny and greenish.
