The books suggested require me to already know the word in order to find the meaning... Is there a reverse-type list anywhere?
I get your point, and that is a useful thing, to be sure. The usual course of events is trying to identify a plant (keying it out), starting by comparing it to some botanical descriptions that use the words in the glossary...
If, instead, you are going to describe plants in scientific detail (rather than compare them to existing descriptions), then that reverse-list would be especially necessary, but that's not the usual way it goes. If you get what I mean...
