I believe it is a peace lily or Spathiphyllum wallisii. I’ve included some care information for you here. Bright indirect light to dark shade. Keep indoors & warm over the winter. Water well over the summer months and less over the winter. Place in a pebble tray or mist regularly to keep up humidity. Wash the leaves regularly. Provide a liquid feed every month over the growing season. I’m a student at Gwinnett Technical College. For details on the department and classes go to http://www.gwinnetttech.edu/horticulture/
