Microsorum pteropus 'Tropica'
is a very ornamental plant named after Tropica Aquarium Plants, Denmark.
The leaf margin is initially dentate in shape. Later, the tooth-like
projections become longer, and on old leaves they may form relatively long,
thin lobes. On older plants, the leaves may grow up to 30-40 cm length. As with
the ordinary Microsorum
pteropus, adventitious plants form on the old leaves. This initially
occurs at the leaf margins but may also take place on the leaf surface
itself. These adventitious plants do not acquire the characteristic leaf
lobes of Microsorum pteropus 'Tropica'. There, this plant can only
be propagated by dividing the creeping rhizome. Formation of sporangia has
not yet been observed on this fern. Microsorum pteropus 'Tropica' is
well suited for both background and solitary purposes in large aquaria. See
also Microsorum
pteropus 'Windeløv' - another Microsorum cultivar from
Tropica. Also, the article Microsorum
pteropus 'Windeløv' and Microsorum pteropus 'Tropica' provides more
thorough information.
