Platycerium bifurcatum, the elkhorn fern or staghorn fern, is a species of fern native to Java, New Guinea and southeastern Australia, in New South Wales, Queensland and on Lord Howe Island. It is a bracket epiphyte occurring in and near rainforests. Growing to 90 cm (35 in) tall by 80 cm (31 in) broad, it has heart-shaped sterile fronds 12–45 cm (5–18 in) long, and arching grey-green fertile fronds which are forked and strap-shaped, and grow up to 90 cm (35 in) long.
