The species is primarily rheophytic and closely related to the genus Spathiphyllum. Holochlamys closely resemble Spathiphyllum except that in Holochamys the spathe clasps the spadix. Also, the inflorescence rots quickly after flowering which doesn't occur in Spathiphyllum. The inflorescence emerges below the foliage and has a white spathe and spadix. The spadix tends to be about the same length as the spathe and produces a leathery fruit. Contained within the fruit are very small seeds. The leaves can vary greatly in size, but they tend to be either oval or lanceolate.^[3][4][5]
