triangular in cross section (the mnemonic that I learned as an
undergraduate was Sedges have wedges); leaves are alternate and 3-ranked;
the base of the leaf is a closed sheath around the stem and continues with
a free blade (as in the grasses). The inflorescence is a spikelet
(as in the grasses). The flowers may be perfect or imperfect, in
which case the plant is monoecious. The flowers are subtended by
bracts and the tepals are reduced to scales, if present. The
androecium is usually of 1-3 stamens. The gynoecium is of 2-3 fused
pistils. The fruit is an achene or nutlet. The family has 104
genera and 4,500 species.
