Botanical name Pyrossia rupestris
A common name Horseshoe Felt Fern
JuvenileAll of these Pyrossia rupestris are growing on Syzygium floribundum on a south facing hillside.
I can only guess this Pyrossia rupestris had a good year, it really hadn't stopped raining for most of the last 6 months or so when this photo was taken. All of the fronds below are fertile fronds, the round ones, like those to the right are sterile fronds.
