asplenium australasicum

The bird's nest fern, or crow's nest fern (Asplenium australasicum) is an epiphytic Australasian species of fern in the family Aspleniaceae.

Asplenium australasicum was originally described by English botanist John Smith in 1857 as Neottopteris australasica. He had reclassified the already known A. nidus in its own genus Neottopteris. Other botanists reclassified the genus as a section, Thamnopteris, within the genus Asplenium, and William Jackson Hooker gave it its current binomial name in 1859. ...
