Thank you, JKP! I will certainly consider your suggestions! Ideas for the identification of the plants marked with ??? would be particularly welcome 
At the moment I only have time to comment on this passage:
In "branca leonina", the suffix -ina is not a diminutive, but has the function of transforming a noun into an adjective.
Other examples:
"branca cervina" (deer's foot, from "cervo")
"aglio ursino" (bear's garlic, from "urso" i.e. "orso")
"pan porcino" (swine's bread, from "porco")
If I understand correctly, the adjective "leonine" with the same meaning exists in English too.
In other words, "branca leonina" is perfectly equivalent to "branca leonis". By the way, "cat" in Italian is "gatto". I don't think I have ever seen "leonino" used as a noun and it certainly cannot mean "cat".
