Bacopa is an emersed
plant. This small sprawling herb is common in fresh and brackish waters. At least three species
of bacopa are native to Florida (Wunderlin, 2003). This species, smooth water hyssop, is distinguished
by its white
flowers, and is distributed throughout the southernmost U.S. (Kartesz, 1999).
Bacopa
leaves are succulent and relatively thick. Its leaves are only 1/8 inch wide and
5/8 inch long. Leaves are oblanceolate, and are arranged oppositely on the stem.
Flowers are small and white, with 4 or 5 petals.
