Staghorn Fern - Platycerium Bifurcatum
This is a fascinating houseplant with unusual upper leaves resembling stag's horns, hence the name.
Platyceriums have a slightly waxy texture which you must not remove (it’s a protective coating) and at the base of the plant you will find flat round basal fronds, or shield fronds, which go brown with age - this is an integral part of the plant so don’t remove or damage these.
The lower drooping fronds often have an unusual disk that catches insects for nutrients.
