Cryptocoryne x willisii

This Cryptocoryne from Sri Lanka used to be called Cryptocoryne nevillii, but that is the name of a species that was never used in aquariums. Like many other Cryptocorynes, not much happens in the first month after planting. After planting, it begins to grow and readily produces many runners that form a compact clump. The plant reaches 7-20 cm in height and 7-15 cm in width.
