Cleistocactus glaucus is a species of Cleistocactus found in Bolivia.
Cleistocactus glaucus is a cactus species characterized by greenish-gray, columnar stems that branch from the base. These stems are typically 1 to 2 meters long and 3 to 4 centimeters in diameter. The plant features 12 to 18 obtuse, notched ribs that are 3 to 5 millimeters high. Areoles are white or brownish, are 2.5 to 4 millimeters in diameter and spaced 4 to 6 millimeters apart along the ribs. These areoles bear chestnut-colored spines. Among the spines, there are 1 to 3 central spines that are stronger and measure 1 to 2 centimeters long and 7 to 9 radial spines that are 0.4 to 0.7 centimeters long; the uppermost radial spines are absent.
The flowers of Cleistocactus glaucus are radially symmetrical (actinomorphic), straight, and tubular, measuring 3.2 to 4.2 centimeters in length. They are orange-red in color and have an ovary covered with numerous scales. The stamens are white. Like most species in the genus, the flowers only partially open. The fruit is spherical (globose), red, and approximately 1 to 1.5 centimeters in diameter. Inside, it contains shiny black seeds that are about 1.25 millimeters long and 0.75 millimeters wide. [1]
This species is native to Bolivia, specifically in the La Paz department in the northwestern part of the country. C. glacus typically grows in the seasonally dry tropical ecosystems. [2]
Cleistocactus glaucus was first described by the German botanist Friedrich Ritter in the scientific journal Taxon in 1964.
