Plantainia!
I think you might have a type of ginger there, I have recently seen a beautiful 'new' ginger that had dark foliage like yours, and a bright orange flower. Your plant - if it is a ginger, but also if it is a Philodendron - would love to be in a moist humid environment. If you have it indoors with heating it might just be getting too dry. Place it in your bathroom, or on a saucer with water, to give it more of its natural rainforest floor environment.
Someone else may have a better identification....
