What literature on biology to choose?

Question

Clustering

Hello. It's June, which means it's time to plant irises. And what about irises?
First, irises bloom from late May to July.
Secondly, this genus of plants has about 800 species with a rich variety of shapes and shades.
Thirdly, at the beginning of the 20th century, Ronald Fisher invented discriminant analysis, and Ronal Fisher just demonstrated the work of his algorithm using the example of classifying different types of irises.
I would also like to demonstrate a similar experience.
Knowledge of data analysis is enough, only knowledge of biology is not enough.
Well, I don't want to wait for the start of Mooc courses, so I need literature on biotechnology.
And of course, it is a guide to irises .
Do you have any recommendations?
Please share Russian versions rather than English ones. I do not yet trust such literature in foreign languages.
