Species
Cuzcoensis
What a cuzcoensis looks like, where it has been collected, and the other names growers meet alongside it.
What it looks like
It reportedly grows five to six meters (16 to 20 feet) tall and much branched, light green when young, with seven or eight low, rounded ribs and very stout, rigid spines, often twelve at an areole and sometimes seven centimeters (almost three inches) long.
The name
The International Plant Names Index records Trichocereus cuzcoensis Britton & Rose as a validly published name, first published in 1920. Reportedly, the Caryophyllales Network, the working taxonomy for the cactus family, accepts Trichocereus cuzcoensis and carries both Trichocereus knuthianus and Trichocereus tarmaensis in its synonymy.
Where it grows wild
Reportedly, its wild collections come from Peru. Reportedly, collectors label some of those plants with a second name after the species — uyupampensis, puquiensis and schoenii — treating them as forms within cuzcoensis rather than as species of their own.
Names in the library
A clone name is not proof of a species, and a photograph is a pointer rather than an answer.
