The spots on your rexes are some kind of fungal disease. It usually happens in cooler temps. It looks ugly but usually not fatal. Remove the worst leaves and try to keep the leaves dry while indoors. Spray if need be. Milstop is supposed to be great stuff (I just ordered some).

Cissus discolor usually defoliates when I move them in for winter. If you can keep the humidity up they will sprout new leaves but it seems to be a battle between too dry and keeping them happy. I tolerate the bare stems in winter knowing when I move them out they will quickly produce new growth.

Serratipetala and brevirimosa do have that exotic look and probably come from the same region of the world.

Here is a picture of both when I was in Thailand. The brevirimosa looks like it has been moth eaten though.
