One theory I never seen considered is that the text means nothing, it's a distraction or later addition unrelated or loosely related to the main content, which is all on the pictures.
In other words, the pictures are the original thing and main content. I would guess they're not about bothanical stuff, but instead use names of bothanicals and other alchemical ideas from the era it was written.
My guess is based on the idea that plant names and alchemical ideas last a long ass time. They're perfect for encoding something meant to not be changed by common text-altering techniques (adding punctuation or accents to non-puncuated or non-accented languages, deriving letter-casing from non-cased letters and so on).
