Pterostylis arfakensis

Pterostylis arfakensis is a plant in the orchid family Orchidaceae and is endemic to Indonesian West Papua in New Guinea. It was first formally described in 1917 by Johannes Jacobus Smith who gave it the name "Pterostylis papuana" var. "arfakensis". The description was published in Lilian Gibbs's book "A Contribution to the Phytogeography and Flora of the Arfalk Mountains" from a specimen collected in the Arfak Mountains. In 2002 David Jones and Mark Clements raised it to species level as "Pterostylis arfakensis".
