I no longer have this plant but it was not labeled when I purchased it from a local flea market vendor and I don't think it's possible to know for certain that it's a named cultivar.
To paraphrase the text below the photo on the page you linked to:
There is some uncertainty about this species although from the photo, it appears to be identical to the collection identified as E. cupreata 'Manaus'. It is reported to be common in Brazil although not apparently in cultivation outside of that country.
With Lin, lets leave them where they are.
