[3] The species was first recorded in China by Jesuit missionary João de Loureiro.
[4] Xylosma congesta can grow up to 8–10 feet (2.4–3.0 m) tall and wide.
[5] New leaves are a red-bronze colour that mature to a bright green.
Although the species seldom flowers, small, black berries can be produced, which attract birds.
The ethanolic extract of its leaves is antimelanogenic (prevents melanogenesis) and is used in skin products.
