Daphniphyllum macropodum is a shrub or small tree found in China, Japan and Korea. Like all species in the genus Daphniphyllum, D. macropodum is dioecious, that is male and female flowers are borne on different plants. The timber is used in China in construction and furniture making. It is grown as an ornamental plant, chiefly for its foliage.
Daphniphyllum macropodum is a small tree or shrub, usually 3–10 m (10–33 ft) tall, but occasionally up to 20 m (66 ft) tall. It has long leaves, 14–25 cm (6–10 in) long by 3–6.5 cm (1–3 in) wide, with purplish red stalks (petioles) and conspicuous veins. The leaves are arranged in a tight spiral, almost like whorls at the branch tips. Very young branches are red, turning brown with age; older trunks are greyish brown.
The clusters of flowers (inflorescences) emerge from leaf axils on the previous year's growth. Each cluster has a pink bract at its base which initially encloses it; they have been described as being like "miniature tissue-wrapped bunches of grapes". The tiny flowers, which have a disagreeable smell, lack sepals or petals. Each plant is either male or female (i.e. has flowers with either functional stamens or functional ovaries). Male flowers have 6–12 pink stamens, about 3 mm (0.1 in) long. Female flowers have a single green ovary, 2–3 mm (0.1 in) long; they sometimes also have staminodes – nonfunctional stamens. When female flowers are fertilized, purplish brown fruits (drupes) develop, about 1 cm (0.4 in) long.

Daphniphyllum macropodum was first described by Friedrich Miquel in 1867. In 1966, Tseng Chieng Huang reduced it to D. himalayense subsp. macropodum. Other sources, such as the Flora of China and the World Checklist of Selected Plant Families (WCSP), do not accept this placement. Further synonyms include D. humile Maxim. ex Franch. & Sav., which has also been treated as D. macropodum subsp. (or var.) humile, names not accepted by the WCSP.
