Egeria densa
Brazilian Waterweed
Not native to Florida
An occasional plant that grows submerged in canals, ponds and streams in scattered counties throughout Florida. Native to South America, it is found throughout much of the United States except Maine, the upper midwest, Idaho and Nevada. Also occurs in British Columbia.
Similar to the highly invasive hydrilla. Brazilian waterweed has longer leaves, 2-3 cm (3/4 to 1-1/4 in.) in length, and minute marginal teeth that usually require magnification to see. The strap-like leaves are in whorls of 3 to 6 around the stem. Flowers have 3 white petals, are up to 2 cm (3/4 in.) across and are held above the water on long stalks.
