Hello all! I work in the Botany department and someone else in the greenhouse was about to throw away some plants so they said we could take them. The only problem is that I don't even know what species they are, which makes looking up online how to care for them difficult. I was wondering if anyone here could identify them. I took some pictures.

Any help would be appreciated!
