I think your task is classification. So, the first thing that we must provide is the feature or attribute from something that we want to classify. Maybe you can extract those taxonomic guides become the features or attributes and the classes from the label of the data. Then we can use machine learning classifier to do your diagnostic.

I know that I should use this evidence in the classification of any plant. My question to the researchers was whether they are specific to a specific plant or whether they will be explained to these evidence

Thank you for your interest in the subject and wish you all the best

It is a very large field of study, and needs to be subdivided into an area of interest for making a chance to contribute something new.
