I have recently taken charge (actually RESUMED charge) of a bunch of tropical foliage houseplants. I already know or have identified 22 of them, but I have 2-4 I cannot identify. I'm hoping for some suggestions from you knowledgeable folks.

All of these plants started out in 2007 as cuttings in a single gift arrangement given to the library where I work. They've had varied experiences since then and have all been propagated by cuttings many times since then. Their last caretaker over fertilized and underwatered them which is why I took over their care. I'm trying to salvage what I can, and I need to identify these plants so I know what to do and what not to do.

I'm guessing the lush, greener plants in the photos at the top are some sort of Dieffenbachia???

Any help in identification would be greatly appreciated!

Thanks,
