Platycerium bifurcatum

The genus name Platycerium comes from the Greek platys (flat), and ceras (horn), while the specific epithet bifurcatum means bifurcated or forked. Both names are referring to the fertile fronds.[4]

Platycerium bifurcatum is cultivated as an ornamental plant for gardens. With a minimum temperature requirement of 5 °C (41 °F), in temperate regions it may be grown outdoors in sheltered locations, otherwise as a houseplant.[3] It has gained the Royal Horticultural Society's Award of Garden Merit.[5][6]
