Spathiphyllum cochlearispathum
Spathiphyllum cochlearispathum is a plant species in the family Araceae. It is native to southern Mexico and often cultivated. When cultivated as a houseplant, Spathiphyllum cochlearispathum is commonly called peace lily. Taxonomic history
Frederik Michael Liebmann originally described the species in a separate genus Hydnostachyon, which he described as having a concave (spoon-like) spathe Spatha foliacea persistens cochleariformis, from which he formed the species epithet cochlearispathum. The species was moved to the genus Spathiphyllum by Heinrich Gustav Adolf Engler. Care instructions 
Water only once soil is dry and the plant begins to wilt, then saturate the soil. The peace lily likes light, but absolutely no direct sunlight, not even for short periods. References
