Description
These branched, aquatic herbs are covered in leaves. They may have an alternate, sub-opposite or whorled arrangement.[5]
The unisexual flowers are surrounded by auxiliary bracts. The male flowers have a six lobed perianth arranged in two rows. The outer lobes are slightly larger. They have three stamens and two to three staminodes. There are multiple flowers per bract.[5]
The female perianths are also made up of six lobes, with those making up the outer layer also being larger than those of the inner layer. The one chambered ovary has three partial placentas. The style is as long as the perianth tube. There are three stigmas, which may be forked. There is one flower per bract.[5]
