Description
[edit]Harrisia tetracantha grows in a shrub-like to tree-like manner, is usually branched above the ground and reaches heights of up to 3 meters. The blue-green to gray-green shoots have a diameter of up to 6 centimeters. There are eight rounded and tuberous ribs. The single, strong, initially brownish central spine later becomes white to ash-gray. The four to seven white marginal spines have a brown tip.
The flowers reach a length of 18 to 22 centimeters.[1]
Distribution
[edit]Harrisia tetracantha is widespread in the Bolivian departments of Cochabamba, Chuquisaca, Potosi, Santa Cruz and Tarija in dry scrub forest at elevations of 1200–2600 meters.[2]
Taxonomy
[edit]The first description as Cereus tetracanthus was made in 1855 by J. Labouret.[3] David Richard Hunt placed the species in the genus Harrisia in 1987. Further nomenclature synonyms are Eriocereus tetracanthus (Labour.) Riccob. (1909), Trichocereus tetracanthus (Labour.) Borg (1937), Roseocereus tephracanthus (Labour.) Backeb.
