what is this plant
we work at the university of Maryland Baltimore downtown. We have a plant which I am going to attach 2 photos of. It started doing a really different thing. It got this big fat pod and wouldn't open so we did nothing and finally after days went by and it got bigger/fatter, it opened. Well then that night it closed again and now we really want to know what it is.
Based on your photos the plants looks like it may be a type of Anthurium. The plant looks mature. It may be helpful to Google Images.
