Why this two plants, despite being from different families have so similar black spots on their leaves? Why evolution favour this? What is the purpose of to have small black path on your leaf? I hope this is not so borring question.

HI Lukas!

It's not a boring questions, I just suspect that it's stumped everyone!

Please could you post a picture of each of your plants? I have had a look and have not found spots on either of them. This might help!

I have seen something similar with "Lords and Ladies" or Cuckoo Pint (Arum maculatum) where some have spots and some don't, but I'd be interested in seeing your plants.
