David, does this look anything like your syngonium? Mine popped up in a brug pot over a month ago. I know I didn't plant it there. It possibly came from a 75% off pot from a big box store. The edges of the leaves are saw-toothed.
terra firma, I Googled your suggestion of possibly ID and that led me to a "mini" version of the pixie. Syngonium podophyllum 'mini pixie' It's sure close!
