Typha is cattails or bullrush as they are known in elsewhere.
Scirpus is one of the many sedges also know as bullrush.
http://en.wikipedia.org/wiki/Scirpus Juncus consists of about 225 species of grassy plants commonly called
*rushes* (common names can be so

Sedges have edges
and rushes are round
and grasses, like asses, have holes.
