The linked page is an image which appears to be labeled with the name of the plant in four different languages, which I would guess are Latin ("Lat."), Malay ("Mal."), Arabic ("Arab."), and Sanskrit ("Bram.", which based on the following page appears to be "lingua Bramanum", which I assume is "the tongue of the Brahmins".)

The text is definitely Latin, but some things about it look odd to me. (I'm looking at page 107, right after the linked drawing.) Do you know what the circumflexes and graves signify?

The E in maximè is long, but so are unmarked Es in habEtur, rubEscente, and diffundEnsque. And the Us in verùm and cùm are short.

The circumflexes appear to be much rarer, but I see "sub eâ". That could be a helpful way to set off the ablative case from the nominative, but later down on the page I see "Folia cùm bina", unmarked.
