In an 2020 blog post, JKP discussed the simple encryption applied to some plant names:
You are not allowed to view links. Register or Login to view.

But if you look closely at the images (like the "Peonia") you should see that the "encryption" actually consists of vertical strokes being drawn over the original "plaintext" name in a different ink (yellower and semi-transparent).  

All the best, --stolfi
