Common Name:  Green cabomba

Scientific Name:  Cabomba caroliniana 

Cabomba caroliniana is a submersed, rhizomatous, aquatic perennial that can have stems up to 2 m (6.5 ft.) long. It has two types of leaves. The petioled, submersed leaves are opposite, and sometimes whorled, peltate in form, and are 2-5 cm (0.75-2 in.) in width. These leaves are repeatedly divided into filiform segments. The small floating leaves are few and linear-elliptic in shape, have entire margins and often have a basal notch. These leaves are 6-20 mm (0.25-0.75 in.) long. The long-peduncled (3-10 cm (1.2-4 in.)) flowers are most often white with yellow at the center, but are rarely pink or purplish. The sepals and petals are about 1.25 cm (0.5 in.) across. The petals are auriculate at the their bases, and obovate in shape.
