Bruce, when trying to ID an aroid it can be very helpful if you post a good closeup photo of a single leaf, both top and bottom. Do your best to make sure the petiole that supports the leaf is clear in the photo of the bottom of the leaf since it can provide identification characteristics. A photo of the stem (central axis of the plant) as well as a the cataphyll that surrounds any new blade can give important clues. Of course, the biggie is the inflorescence if you're lucky enough to be able to capture one.
The leaves of an aroid can be extremely variable and don't always provide enough information to offer a good ID. This could be a form of Philodendron erubescens but more detail will help. Do you see "red" anywhere on the underside of the leaf or on the petiole?
Thanks!
Steve
