Houseplant with shiny medium green leaves

My aunt gave me this plant and I have no clue what kind it is; but I am sure that some one on this forum will know and it would be greatly appreciated if you can tell me what it is.

Is that a staghorn fern???

 

It looks like a Queen of the Night.
Epiphyllum Oxypetalum

 

It looks like some kind of Epiphyllum, or orchid cactus...

 

Yes, it is a "Queen of the night." Thank you so much, now I have an idea on how to take care of it. I am looking forward to it's blooms sometime in the future. It is about a year old. Thanks again to all of you,
