I don't recognize my anubius!!

Can some please help me with this? I bought several anubius
about a year ago under the name "nana". It does not look
like the "nana" I have seen in photos. The leaves are much
more egg shape that the spears I have seen. It is only about
3-4 inches tall and grows well, but the leaves are about 2/3
as wide as they are long. By the way,they do come to a point
Is this just a variety of "nana" or something else?
