I cannot give a sourcefor the name Dieffenbachia hoffmannii but I have in the 60s and 70s grown thisDieffenbachia, in fact it was a favourite of mine. The name is no longer valid,if it ever was, but D. ‘Exotica’ or ‘arvida’ may be amutation of it, whatever it is. Both are said by Graf to be from Costa Rica.

The accompanyingillustration may perhaps answer questions about markings on stem and petiole.

According to all the Kewsites as well as TROPICOS there is no such species. Can you tell us thesource of the name?

Hello List,

Can anyone point me to a goodphoto of Dieffenbachia hoffmannii? I would like to see the petioles withthe leaves, if possible. I am trying to double check an ID.

Thanks a lot for any help.
