NB: There are unusually many species of the four genera Actinodaphne, Beilschmiedia, Cinnamomum and Cryptocarya which have been assessed as "Critically Endangered (Possibly Extinct)" by the IUCN's RedList. Most of these are endemic to New Guinea, and while they are under threat from deforestation, the implication is that most of these have never been searched for again and hence the categorisation is rather theoretical/hypothetical. It is not clear how many have been unsuccessfully searched for, which would be a truer criterion than that which seems to have been adopted idiosyncratically by the IUCN RedList.
