Cyperaceae: Sedge Family
This family contains 4,000 species in 70 genera. They're most abundant
in the temperate and colder regions of the globe. The largest genus is Carex
which which has flowers that are unisexual on two parts of the inflorescence.
Papyrus is made from a sedge, in particular, Cyperus papyrus
which grows in Egypt along rivers.
Systematics: Just remember that sedges have edges.
While this isn't always the case, it is usually a good way to differentiate
grasses from sedges. Sedges usually have solid 3-angled stems with leaves
alternate and also in 3 angles. Usually the perianth is lacking and when
present is composed of simple scales and bristles. There are typically 3 stamen and
branched styles.
