It looks like an aeschynanthus to me. Leaves are similar to 'Thai pink' and 'coral flame' but it's hard to tell without bloom. EA labels everything as A. radicans but often puts the correct species name or hybrid name in quotes below where it says radicans. You might have to wait for it to bloom before you know more though. Hope this helps.

I am quite sure it Aeschynanthus but probably some hybrid of radicans or lobbianus. I once bought similar plant in HD and it bloomed just like radicans with chocolate calyces and deep red corollas.

Thanks! You're right that when I looked at the growth habit of the plant, and the new leaves, it was similar to the way my other aeschynanthus looks, but the leaves were so clearly different I just wasn't sure what I had on my hands. Thanks for the replies, those give me a good idea & I will have to wait for the blooms I guess!
