This plant has a unique leaf with a brown/green color above and burgundy on the underside, it also has a unique deeply serrated edge, it produces horizontal side shoots that should be removed to keep the plant growing neatly it will also stay more compact with high light and has a slow to medium rate of growth, the plant can also be attached to wood or rocks.
Takashi Amano uses this plant a lot in it's recent aquariums. Never saw this plant available in my region. The fact that this is a stem plant and that it can be attached like the bolbitis or microsorum makes it interesting.
Awesome stem plant, the leaves look like skinny oak tree leaves. I'm very fond of stem plants that grow slowly since they don't overrun the tank and require constant trimming. Great compliment to tanks with driftwood IMO.
