Sorry I don't have a photo. A friend is asking me to help ID a vine that's growing on his neighbor's fence in Houston. (I've also posted this question in Texas forum, but no answers.)

The vine is about 10' high and grows rampantly. Leaves look like some type of philodendron and also send out spathes. But I've never seen a philodendron grow this tall.

Also, the leaves aren't the "fingered" shape of ordinary philodendrons but more elongated and slightly triangular.

Good grief, that's not a very good description but maybe someone can point me in the right direction.
