Ceratophyllum echinatum
Also called Hornwort, Prickly Coontail, Prickly Hornwort, Spiny Hornwort, Spring Hornwort
Spineless hornwort is a submerged aquatic perennial with no true roots, found in ponds and lakes. It grows best in cool, still or slow water with plenty of light and needs no soil.
Ceratophyllum echinatum, known as prickly coontail or spiny coontail, is an aquatic, perennial plant found in North America. Its name comes from fruits, which have a warty surface and long spines. Spiny coontail can be found in ponds and lakes, principally in eastern North America. It is the only species of its genus endemic to North America.
Ceratophyllum comes from the Greek keras, "a horn" and phyllon, "leaf", which is alluding to the stiff and narrow leaf divisions. The specific epithet echinatum comes from echinus which means sea urchin or hedgehog.
