i came across this article on IAS site aroid.org in reference of A.zebrina names incorrectly used by sellers.
http://www.aroid.org/gallery/l...
there are 2 entries in ATP db that are mentioned in the article as 'incorrect usage' due to the fact that neither one was registered.
they are: Alocasia zebrina 'Tigrina Superba' and Alocasia zebrina 'Reticulata'.
i don't know what the current view on the matter is, so i thought to let you know about the article.
