Shrub 0.3 - 3 m tall Leaves: bright green above, paler beneath, 2 - 5 cm long, narrow elliptic to narrow egg-shaped with a rounded or pointed tip, non-toothed or with few teeth. Flowers: either male or female, borne on separate plants (dioecious), yellow, tiny, narrow-petaled. Fruit: fleshy with hard nutlets in the center (drupe), red, rarely yellow, 6 mm in diameter, nearly spherical. Twigs: purplish, becoming ash gray.

Similar species: Ilex opaca, Ilex verticillata, and Nemopanthus mucronatus have very similar fruit. However, other characteristics make them easy to distinguish from each other. Ilex opaca is a tree that has evergreen, oval to narrow elliptic, leathery leaves with a few spiny teeth along the margins. Ilex verticillata is a shrub that has deciduous, elliptic to egg-shaped leaves with sharply toothed margins and a hairy lower leaf surface.

Flowering: late April to late May

Habitat and ecology: Bogs, swamp forests, damp thickets and woods.

Occurence in the Chicago region: native

Etymology: Nemopanthus is derived from the Greek words nema, meaning thread, pous, meaning foot, and anthos, meaning flower, referring to the thin flower stalks. Mucronatus comes from the Latin word meaning "short, pointed tip,"referring to the leaf shape.
