Cleistocactus glaucus
species of plant
Cleistocactus glaucus is a species of Cleistocactus found in Bolivia.
Description
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 cm (1.2 to 1.6 in) in diameter. The plant features 12 to 18 obtuse, notched ribs that are 3 to 5 mm (0.12 to 0.20 in) high. Areoles are white or brownish, are 2.5 to 4 mm (0.098 to 0.157 in) in diameter and spaced 4 to 6 mm (0.16 to 0.24 in) 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 cm (0.39 to 0.79 in) long and 7 to 9 radial spines that are 0.4 to 0.7 cm (0.16 to 0.28 in) 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 cm (1.3 to 1.7 in) in length. They are orange-red in color and have an ovary covered with numerous scales. The stamens are white.

Why this record matters
“Cleistocactus glaucus” is worth following because a concise public description often conceals a longer documentary argument. Here, Cleistocactus, glaucus and species provides the most credible route into that argument.
The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated Jan 30, 2026. The linked authority identifier is Q42682659. None of the 0 selected statements returned an explicit reference.
Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
