Provisional IUCN conservation assessment. Critically Endangered CR Bla,b(iii) 
(IUCN, 2016). The species appears to be common at the type locality but it may be 
locally endemic as it has not been recorded from elsewhere, either from herbarium 
specimens or during the first author’s fieldwork. Much of PNG Western Province’s 
lowland rainforest has been, or is being, logged (Shearman et al., 2009) and the type 
locality is not inside a protected area and may be lost in the near future.
