Asplenium dimorphum
Definition
A rare species of perennial fern in the Aspleniaceae family, endemic to Norfolk Island in the Pacific Ocean, popularly known as the two-branched spleenwort. It stands out due to its spectacular structural phenomenon of foliar dimorphism, developing two completely different types of fronds on the same plant: the sterile ones are broad, glossy, and partially divided, while the fertile fronds, which bear the spores, are finely dissected into thread-like segments, giving the plant a highly distinctive exotic look.
