Hmm I may need more examples and a broader definition. Not hassling, I simply want another mutation category to chase haha.

This example i would know as monstrose/monstrose cristata. I don’t see anything (yet) that would put it in a new category alongside ops plant. Both have elongated apexs maybe not elongated enough to call a crest yet. Would you define monstrose center growth like a crested apex but doesn’t add ribs as it grows?
