Provisional IUCN conservation assessment. Critically Endangered CR B2a,b(iii) 
(IUCN, 2016). The type locality is along the famous Kokoda Track that is still covered 
by thick forest, but further development along the track with expanding population 
may reduce the forest cover greatly. The forest in the two recently recorded localities is 
under high pressure from expanding population because of slash-and-burn agriculture 
that later turns the landscape into eroded abandoned grassy fields. Hoya carrii has not 
been recorded elsewhere, neither in herbaria nor during the first author’s fieldwork.
