Nephrolepis is a genus of about 30 species of ferns. It is the only genus in the family Nephrolepidaceae, placed in the suborder Aspleniineae (eupolypods I) of the order Polypodiales in the Pteridophyte Phylogeny Group classification of 2016 (PPG I).[1] (It is placed in the Dryopteridaceae in some other classifications.[2]) Species in this genus include plants commonly referred to as Boston ferns.[3] The fronds are long and narrow, and once-pinnate, in the case of one Bornean species reaching thirty feet (nine meters) in length.[4]
