Chloranthus serratus is a 30-60cm perennial herb that grows in forests in hilly districts. Leaves attach oppositely on the stem tops in 2-3 pairs, somewhat apart. Leaves are glossless green, with spiny serrations on the margins. Spikes generally comprise two, varying from 1 to occasionally 3-5; short filaments curve inward to envelop the pistils. Central stamens attach two anthers inside their bases, and two stamens outside set the anthers one each. Bloom time: April-June.
