Wood Club Rush grows in damp places in hollows in wooded districts, by the roadside in ditches, but usually where there is woodland, and in the woodland districts as a rule. It grows on the borders of rivers where they have overflowed and left pools.
The stems are stout, leafy, 3-sided, solitary. The leaves are long, keeled, broad, and flat. The flowers are borne in compound branched cymes with slender branches, terminal, and the spikes are in stalkless and stalked clusters, with blunt-pointed, finely furrowed glumes. There are 6 barbed bristles. The nut is bluntly pointed, 3-angled, inversely egg-shaped.
Wood Club Rush is 18 in. high. The flowers bloom from July up to September. The plant is a herbaceous perennial, propagated by suckers.
The flowers are pollinated by the wind, and bisexual, and the floral mechanism is similar to that of the Bulrush. The fruit is a nut, which does not open, and falls to the ground when ripe.
This Club Rush is a peat-loving plant, growing in peat soil or clay soil with some humus in woods.
A fly, Agromyza nigripes, infests the plant.
The second Latin name refers to its woodland habitat. It is called also Millet.
