Hydrilla (Hydrilla verticellata) is a rooted, submerged plant with branching stems. Stems may occasionally break loose from the main plant and form large floating mats. Hydrilla will grow in water as deep as 36 feet. Leaves are small and serrated often with small spicules (a sharp tooth-like structure) along the midrib. Upper leaves grow in whorls of three; lower leaves are oppositely arranged.
