Rhaphidophora cryptantha is part of the Araceae family and its native range is Papua New Guinea.  It is hemiepiphytic and shingles the bark of host trees. Leaves are broadly ovate and coriaceous with a cordate base and silver grey venation. Inflorescences arise and open on shoots carried behind the appressed shingling leaves meaning they are often obscured. This plant is sometimes thought to be Monstera dubia; leaves are ascending on Rhaphidophora cryptantha and descending on Monstera dubia.


Genus name comes from the Greek ‘rhaphido’ meaning needle and ‘pherô’ meaning I bear; this refers to the macroscopic needle-like unicellular trichosclereids present in tissues - the purpose of which is to protect the plant from herbivores. Specific epithet comes from the Greek ‘crypto’ meaning hidden and ‘antha’ meaning flowering, this is in reference to the hidden inflorescence.
