Hi everyone, last year I traded with a member on here and I was sent this guy. He told me that he thought it was corrugatus, but after looking at other pictures online of that type, it doesnt seem to match up. He did tell me though, that he wasn't certain. Right now I have a Titanum, Konjac and Bulbifer and the closest resemblance to any of these is the Titanum. I am pretty sure that that is not what it is though seeing as it would be hard to not know you had those. Any help would be greatly appreciated so that I can correctly I.D. this guy (or girl).
There is a resemblance to young titanum, but not enough to make me think it is. My young bulbifers looked more like that. However, the petiole doesn't have any pattern to it other than what appear like vertical lines. Those types of lines are what are on my local Tacca. The leaves can be variable, and include the shape of those on your plant. You may have to wait til it develops more to get a better idea.
These plants are devilishly difficult to ID from a young leaf, as the natural variability plus the natural similarity between many species make distinguishing them a near impossibility. For example, I have a few small A. gigas and they look just like another species I have. If I lost the tags, I'd be hard put to tell them apart even though I know which is which. Unless a person is intimately familiar with the look and developmental progression of a particular species, blooming the plant is the only way to be sure about what it is.
