If I can possibly name your plant I will need information, to guess is to have egg on face. How wide, describe top apex of the leaf, grey, whie rounded or pointed spots, any fine vertical lines, what does the dermis feel like top and bottom, and it looks from the picture that it has a very short periole? How old is that biggest leaf at this time, and how thick are those leaves, in the middle, is there any sign of a spine/rib down the back center, and how wide if the channel if there is one. Jeff is the skin a dull green or a shinny bright color and waxy?
