Unknown Plant Probably a Type of Lily

got this plant from a friend he had it next to a window we are trying to nurse it back dont know what kind of plant it is please help

Wow, there’s not much left to it! First check and see if the leaves are growing out of bulbs in the soil. If there are bulbs, then the plant is probably some kind of lily that is getting ready to “rest” for the winter months. Cut off the leaves, remove the bulbs, store in cool place, and replant in the spring. If there are no bulbs then it’s a Peace Lily (Spathyphlum). Remove the dead or dying leaves. Allow at least the top 1/2 of the soil to dry out before watering. There’s a product called superthriveSuperthrive combines vitamins and hormones to encourage plant growth both above and below the soil line. It's not a plant food so it needs to be used in addition to your regular plant food; the two can be used at the same time. Just put a few drops into your watering can & that's all that's needed to improve the health & appearance of your plants. If your plants are in real trouble, add about 10 drops per 2 gallons of water. SuperThrive works best when the soil is dry.    , you can read about it in the Glossary, that does wonders for stressed plants. You can read all of the care instructions for Peace Lilies in the Popular HousePlant Section of the website.
