Aponogeton rigidifolius has banded undulate submersed leaves that grow to a length of over 60 cm. It inhabits slow to fast flowing waters in the south-west of Sri Lanka. Other than most Aponogeton species it does not form a bulb but a long, thin, ramifying rhizome.

Its scientific name translates as stiff-leaved Aponogeton. It is described as demanding, light-loving plant that grows rather slowly. CO2 injection and a good water movement are recommendable for its cultivation.
