Re: can someone confirm this is Pisang Ceylon?
I am basing my educated guess on the color in the midribs. If that color spreads to the underside of new leaves, it points to PC. I am assuming you know the few types you thought you lost and it shouldn't take much to narrow it down.
If you lose your head and give up, you neither live nor win.
Varieties I supposedly bought: Manzano, Cavendish, Blue Java, Sweetheart, and Gros Michel.
What it seems I actually have: Brazilian, Cavendish, Namwah, Dwarf Red, Gros Michel, Pisang Ceylon, Veinte Cohol and SH 3640, and American Goldfinger. FHIA 1, Paggi and FHIA 17... Always room for one more.
