Here's a link to some free PDFs I've uploaded after Google removed a link to the drive I'd previously put up after somebody snitched on it for copyright infringement. Learning should be free, as it benefits the common good. I recommend starting with "Families of Flowering Plants", "Plant Systematics", & "Evolution - Making Sense of Life" by Carl Zimmer (look up what the difference between monophyletic vs. paraphyletic is, as it will open up a window on the world around you). Again, please do ONLY share the link with people you trust and know.
To access it, you will need to copy and past the following key after clicking on the link below :
