Anubias barteri var. glabra

Anubias barteri var. glabra from West Africa is a beautiful plant with long, narrow leaves.

10-20 cm tall with a rhizome, from which the leaves develop, that grows 10-15 cm or larger. Very easy to grow since it thrives in almost any conditions, although high light intensity should be avoided. Place it instead in shady positions under larger plants. If planted in the bottom, do not cover the rhizome, it tends to rot. It is not eaten by herbivorous fish. 

Anubias barteri var. glabra used to be sold as Anubias afzelii, but the latter is actually a much larger species.
