Like a thread not far beneath this one it appears to be Anthurium radicans x dressleri. The plant is a hybrid cross between Anthurium redicans and Anthurium dressleri.

The cross was done by Dr. Mike Madison at the Marie Selby Botanical Garden in Sarasota, FL and at one time was considered a rare find. A few years ago this plants was commonly released by tissue culture companies.

There was a very large specimen of this cross on display at the International Aroid Society Show and Sale in Miami the third weekend of September, 2009.
