Stiff Hornwort [Ceratophyllum echinatum]
Description
Ceratophyllum echinatum, also known as stiff hornwort, is a species of hornwort that is native to North America. It is similar to Ceratophyllum demersum, but is distinguished by its more rigid structure. The plant lives in fresh water and is free-floating, though it can become loosely anchored in mud. It has whorled leaves and is known for its spiny fruit and its ability to grow rapidly and cover large areas of water.
