bucephalandra "Catherinae Super Mini" is an easy to keep plant with very tiny leaves. It is great for aquascaping and creating scale with it's fine texture. I've also seen this type called "Rosemary Buce" because it's leaves do resemble the size and shape of a rosemary.

In nature, Bucephalandra usually grows on rocks or wood in rivers and streams - much like Anubias, which they resemble regarding use and care in the aquarium. It's an easy plant that can grow well in low tech tanks and in low light.
