Cleistocactus brookeae is a species of columnar cacti in the genus Cleistocactus.
Description
Cleistocactus brookeae grows as a shrub with sparsely branched, upright to columnar shoots up to 50 cm (20 in) long and 3 to 4.5 cm (1.2 to 1.8 in) in diameter. There are 22 to 25 ribs. The areoles on it are close together. 25 to 40 greyish-white or slightly yellowish spines, up to 1 cm (0.39 in) long, emerge from them, which cannot be distinguished into central and radial spines.
The red to orange flowers are up to 5 cm (2.0 in) long and have a diameter of 8 mm (0.31 in). The flowers are bent upwards in a right-angled S-shape above the pericarpell and flattened laterally. They are also somewhat sac-like bulging immediately above the pericarpell. The mouth is askew. The purple fruits reach a diameter of 8 to 10 mm (0.31 to 0.39 in).[2]
Distribution
Cleistocactus brookeae found growing on steep cliffs and rocky slopes close to rivers in the Bolivian departments of Chuquisaca and Santa Cruz at altitudes of 800 to 1300 meters.[3]
Taxonomy
The first description was in 1952 by Martín Cárdenas. The specific epithet brookeae honors the Bolivian plant collector Winifred M. Brooke.
