Spegazzini (1925: 102) published this photograph, although he did
not mention if it corresponds to the type.
Obs.: Spegazzini (1923) created a new name:
“Opuntia molinensis Speg. (nom.
nov.) = O.
Speg. (non Web.), Cactacearum
tentamen, nº 106”,
since the name
was already created by Weber in 1904.
derives from the Greek adjective “tephros (τεφρος)”
meaning “ash coloured” plus the connective vowel
“o” used in botanical Latin for Greek words , and the
word “cactus” (an old genus name) (The genus name implies:
“ash coloured cactus”). The
species name "molinensis" comes from "Los
Molinos", name of the original location from which
the species is native.
