Description

Echinodorus grisebachii 'Amazonicus', also known as the narrow-leaved Amazon sword, is a species of plant that originated from the Brazilian Amazon depression (Rondônia and Pará) where it was found growing submersed in 50 to 100 cm deep stagnant to slow-flowing water. It typically grows to a height of around 40 cm when cultivated submersed, with very narrow, lanceolate leaf blades that curve sideways like a sickle. When grown in an aquarium, it can reach over 60 cm in height and has narrower leaf forms compared to Echinodorus grisebachii 'Bleherae'.
