I have been trying to learn zeraim, but I keep getting stuck on all the names of the plants. Is there any comprehensive listing?
I recommend the book הצומח והחי במשנה by יהודה פליקס. I found it invaluable when learning משניות סדר זרעים. It's in Hebrew but includes, if I recall right, the taxonomic and English names of each plant, and pictures. Not everyone agrees with his identifications of the various types of plant, and, if I recall right, he doesn't always include even major dissenting opinions. It's been a while since I've opened the book, though; my memory may be misserving me.
