Geographical distribution:

This fern is a native of tropical Africa , Australia and tropical Asia. Asplenium nidus either grow terrestrially on the ground, or epiphytically on the trees. Sometimes they grow on rocks (Piggott, 1988).

The sword-shaped fronds grow from the centre of the plant to form an inverted cone. The fronds are very long approximately 50-120cm, and 10-20cm wide, also the leaves or fronds are light green, often crinkled, with a smooth-edged blade and a black midrib that is obvious. The sporangia develop in clusters called sori, covered by an elongated indusium on the back of the fronds. It has roots for absorption of water and minerals from the soil (Koh, 2009). In terms of size this alters according to the habitat (Piggott, 1988).
