Echinodorus cordifolius ssp. fluitans

Hemianthus callitrichoides is one of the smallest aquarium plants in the world, and creeps over the bottom with millimetre-sized round leaves. If planted in small clumps a few centimetres apart, it will spread rapidly and cover the bottom like a carpet. Hemianthus callitrichoides is an attractive foreground plant for small aquariums, and makes few demands. Found on Cuba west of Havana.
