Bird's nest fern

Asplenium australasicum is a species of epiphytic fern in the Aspleniaceae family found in eastern Australia. Common names include Bird's nest fern and Crow's nest fern. Asplenium australasicum grows as shrubby plant, with a rosette of yellow-green fronds which are 60 to 80 cm long and 3 to 21 cm wide. It can be distinguished from Asplenium nidus by its prominent midrib under its fronds, giving the fronds a keeled appearance. The spores form in parallel lines which run in parallel with the veins and oblique to the midrib.
