Platycerium superbum - Staghorn
Family: Polypodiaceae

The dust-fine spores of these massive epiphytes float through the canopy and colonize trees with rough and permanent bark.
Young plants look like flat round plates, gradually developing large deeply lobed sterile leaves ('nest leaves') which stand out from the host tree and catch falling leaves from above providing nutrients.
Pendulous antler-like fertile fronds are produced on older plants.
Large brown patches of spore-cases are visible on the underside of these leaves, just before the first fork.
