Copernicia alba is a South American species of palm tree, which is found in dense pure forests in the humid part of the Gran Chaco ecoregion of Argentina, especially the province of Formosa, and less abundantly towards drier areas. Its common names in Spanish show the various colours (and technical qualities) that its wood takes according to its environment: palma blanca, palma negra, palma colorada ("white", "black" and "red" palm, respectively). In Guaraní it is called caranday, "water palm". Its English trade name is wax palm or caranday wax palm (it belongs to the same genus as the Carnauba wax palm).
C. alba can reach 25 m in height and 40 cm in girth. The trunk is cylindrical, rarely bifurcated, and has a grayish bark with a smooth surface in adult specimens. The leaves are persistent, grouped at the apex of the trunk, and measuring between 40 and 70 cm. The inflorescence is almost 2 m long; the flowers are hermaphroditic, about 4 mm long, with a tubular yellowish green corolla, and arranged in a spiral pattern. Each flower has three ovaries, of which only one develops into a globular fruit, a dark pulpous berry that contains a light-brown, 12 mm long ovoid seed.
Young specimens have a lightweight semi-hard wood, which becomes hard and heavier in grown-up individuals, reaching a relative density of up to 0.92. This wood finds its main use in telephone and electrical line poles.
