RuuddeBlock said:Original label said Cereus validus. A short search on Intranet revealed many of this specific cactus under that name. Unfortunately the name is no longer valid. According to Catalogue of Life it should be Acanthocereus tetragonus, which is a different cactus. According to other sites this should be Cereus hildmannianus instead. To me this seems a reasonable guess,

It simply doesnt possess any features that adult acanthocereus do
It has 5-6 ribs, columnar stems, more than 5 spines per average, fuzz..
All features lacking in acanthocereus, but very obviously present in a lot of cerei...
