You don't really have to be a botanist. They're fairly common trees, sort of like birch, maple, oak, cherry, etc. I actually have a sassafras in my yard.

As for your second concern, all I can say is that Sombra was banished by the sisters together, whereas Nightmare Moon was banished by Celestia alone. As a result, the Elements may have been somewhat stronger against Sombra. I could think of plenty of other explanations, but unfortunately I cannot support them as well as I would prefer. It is certainly worthy of speculation.
