This is an adult full sized leaf from a +12 yr old philodendron. The plant is snaking up a tree and is 3-4m high. The petioles/ leaf stems are rounded and not c-shaped (as in p.xanadu) and the leaf is 40cm from top to tip with the main/ centre rib of the leaf being 30cm. Please I would appreciate any help with the identification of this gorgeous plant as I can find it anywhere online. Could it be P.Eichleri?
