Description

Leucostele skottsbergii grows as a shrub with a few columnar branches that branch out from the base and reaches heights of up to 2 meters. The cylindrical, gray-green shoots reach a diameter of up to 14 centimeters. There are 16 to 21 ribs. The areoles on them are grayish black. The thorns emerging from them are light brown to gray. The usually four to six central spines are up to 12 centimeters long. The 22 to 26 flexible, spreading, bristly marginal spines are not particularly piercing and are up to 6 centimeters long.

The funnel-shaped, white, pink flowers appear on the sides of the shoots and open during the day. They are 10 to 12 centimeters long. Their flower tube is covered with black or gray hairs. The spherical fruits are green.^[2]

Leucostele skottsbergii is widespread in the Coquimbo region of Chile at altitudes of 200 to 800 meters.
