Here I am! On the topic of the group of plants that includes Alocasia zebrina, I have an article on the subject coming out in the newest Aroideana, for those of you who are members of the IAS. If not, perhaps this is a good time to join!
I won't spoil the fun by repeating the article information here, but just to say that I've bred with all three plants (zebrina, "tigrina" and "reticulata) and my results indicate a stability of characteristics (genetic) that would imply more than just a varietal nature. In fact, the distinguishing characteristics are so dominant in crosses that no matter if the parent is something as different as the Borneo Giant, the characteristics of the "reticulata", for example, come through totally.
To add sauce to the goose, I unveil what I call "variant 4", a plant that seems to be intermediate between "reticulata" and "tigrina", and is easier to grow than both of them. Of course, it is high on my hybridization list this year.
