Cleistocactus buchtienii is a species of columnar cacti in the genus Cleistocactus .

Description

Cleistocactus buchtienii grows as a shrub with branched, rigid shoots at the base and reaches heights of growth of up to 1.5 meters (rarely up to 3 meters) with a diameter of up to 5 centimeters. There are about 16 to 19 (rarely up to 22) low ribs present, which are conspicuously notched. The needle-like, reddish-brown to straw-yellow spines are difficult to distinguish between central and radial spines. The 4 central spines are spread out and up to 3.5 centimeters long. The radial spines, which are 8 to 15 to 2 centimeters long, are slender and spread out.

The wine-red to bluish pink flowers are 5 to 8 centimeters long and 9 millimeters wide. The tips of the bracts are burgundy or greenish to dark green. The flowers are straight or very slightly curved, pointing slightly upwards, and are covered with short, dense hairs arising from the scale axils. The stamens do not protrude or hardly protrude, the style protrudes slightly to clearly from the flower. The spherical fruits tearing open at the base reach a diameter of 2 to 3 centimeters. They are yellowish green at the base and light purple above. Seeds are black and 1.2mm. ^[2]
