@plantladylin,
I got a cutting of this cissus today from a friend. It is a great big vining monstrosity. She just called it 'Giant Cissus'.
It has a tripartite kind f serrated leaf. I noticed that you had posted a photograph in the past of Cissus alata. Is that a match to this?

Gina, are you sure it was a photo of mine that you saw somewhere? I don't recall ever posting a photo of I could be wrong but it's not a plant I remember ever growing.

I went through my files on my laptop and the only Cissus I have photos of that I recall growing are the following:
Cissus (Cissus adenopoda)
Rex Begonia Vine (Cissus javana)
Grape Ivy (Cissus alata)
Peruvian Grape Ivy (Cissus rotundifolia)

C. adenopoda I had a few years ago and left it here when we moved back to Daytona Beach; I'll have to take a walk around the yard and see if it's perhaps still out there somewhere.

C. javana .. I've tried it a couple of times over the years but with my neglect, it hasn't stayed around for long.

C. rhombifolia was a popular houseplant for many years but I haven't seen it offered at garden centers or nurseries in a long while.

I've had C. rotundifolia for 10 years; with it's more succulent like leaves, it does better under my neglectful care.

I think its is actually C. rhombifolia. The leaf matches, but this vine was literally huge. The stem is the size of my finger. The nursery 'inherited' the plant from an elderly man who passed away, it was not for sale but she gave me a cutting. It was growing in a cocofiber liner in a wire basket hanging way up in the ceiling because the vines were 10-12 feet long. It had been neglected though.

I take it back not rhombifolia. There are just too many species in the Cissus genus!

Those kinda serrated leaf margins are interesting but it doesn't look like Cissus alata either. A couple of photos on this MOBOT page, click to enlarge: http://www.missouribotanicalga...

I thought maybe Sorrelvine (Cissus trifoliata) but those leaves aren't a match either.

Could it be something in the Vitaceae family other than Cissus? I'm not really good at comparing photos but when googling images, I came across Chestnut Vine (Tetrastigma voinierianum) with similar leaves.

You may have hit on something. Top Tropicals in South Florida has a plant called Cissus tetrastigma listed.
I know that the friend who gave this to me said it was considered 'rare' not that this means jack but it may be an uncommon plant around here anyway

Yes, the leaves in this photo of Tetrastigma voinierianum at the Top Tropicals website sure look like those in your picture: https://toptropicals.com/pics/...

I think its a match. My cutting has tripartite leaves, but the literature states there can be as many as 5 sections to a leaf. I hope it roots, it looks like an interesting plant to grow
