'''''Cryptocoryne undulata''''', also known as '''undulate cryptocoryne''', is a plant [[species]] belonging to the [[Araceae]] [[genus]] ''[[Cryptocoryne]]''.
==Taxonomy== In the literature of the 60's this plant was considered a form of ''C. willisii'' but see the ''[[Cryptocoryne]]'' page for a discussion of the name change and the 'diploid and 'triploid' forms.
==Distribution== It is found in [[Sri Lanka]] and [[Thailand]].
==Description== Its long, ruffled dark green [[leaves]] may grow to more than 14 inches (35 cm) when mature. It is variable in form under different conditions and origin; low light levels may produce light green leaves.
==Cultivation== Considered one of the easier cryptocorynes to grow in an aquarium, it will grow well partially and fully submersed and flowers relatively easily. It prefers bright light and a temperature range of 72-82 degrees F (22-28 degrees C). The 'diploid' form forms runners. Common in the [[aquarium]] trade.
