Leucostele atacamensis (cardón) is a species of cactus from Chile, Argentina and Bolivia. The wood of this species can be used in building and in making furniture.[2]
Description
Leucostele atacamensis has a tall columnar habit, sometimes forming branches in a candelabra shape and becoming treelike. It grows to about 1.5–10 m (4.9–32.8 ft) high, with stems to 25–70 cm (9.8–27.6 in) across. The stems have 20-30 ribs and areoles have a diameter of up to 2 centimeters and become larger with age with 50-100 maroon coloured spines, the longest up to 30 cm (12 in) long. In younger plants, the yellowish to honey-colored thorns are strongly needle-like and up to 10 centimeters (rarely up to 15 centimeters) long. The two to four (rarely up to eight) central spines cannot always be clearly distinguished from the peripheral spines. The rose-white flowers are 10–14 cm (3.9–5.5 in) long, open day and night, borne on the sides of the stems. The dark green fruits are densely covered with hairs, up to 5 cm (2.0 in) long; they are edible.[2]

Systematics
Leucostele atacamensis was first described by Rodolfo Philippi as Cereus atacamensis in 1860. The specific epithet atacamensis refers to the higher mountain areas in the Atacama region of Chile, where the species is found. It was placed in a number of genera, including Trichocereus and Helianthocereus, before being moved to Echinopsis by Helmo Friedrich and Gordon Rowley in 1974.[2] In 2012, Boris O. Schlumpberger reclassified the species into the genus Leucostele.[4]
