Pelecyphora aselliformis

Small, slow-growing Mexican cactus whose tuberculate ribs resemble a woodlouse (whence "aselliformis"). Contains low concentrations of mescaline and other phenethylamines. Sometimes called peyotillo and used by some Huichol bands as an addition to or substitute for true peyote.

Limestone gravels of the southern Chihuahuan Desert. Tiny, half-buried in habitat — easily overlooked.

The names this organism has been given by the cultures that have lived alongside it. Each carries an entire relationship — what is sacred is never simply translated.
