Bird's Nest Fern

We have talked about epiphytes a few times on this blog and really, there can't be a better place to revisit the subject than in a valley forest in Hawaii. Below, you can see several different epiphytes growing in the canopy of a monkey pod tree (Albizia saman, more on that later).



Perhaps most beautiful are the apple green leaves of bird's nest fern (Asplenium nidis). Bird's nest ferns share their genus with 700 other species, some of which are very similar and often confused with Asplenium nidis.



This particular species can grow in trees as it is above or can grow terrestrially. They are also popular houseplants. Many of the species of Asplenium are generally referred to as spleenworts. This knowledge may give us pause as we consider the genus name again: Asplenium literally means "without spleen". It was thought, due to the spleen-shaped spores on some species of this genus, that this plant would help reduce swelling of the spleen.



Above you see some additional epiphytes, including staghorn fern (Platycerium) and what appears to be an epiphytic bromeliad, perhaps Nidularium.
