Cryptocoryne undulata

It is characteristic for this species that it has a small internodium between each leaf. Normally the leaves of Cryptocorynes grow out from a rosette which is so compact that the stem between the individual leaves is invisible. When you buy Cryptocorynes in pots, it is important that they are not planted in a lump but separated into smaller portions and preferably planted a few centimetres apart. See other Cryptocorynes for further information
