- Occurrence of Racomitrium pruinosum, an austral temperate amphipacific species, in the tropics is confirmed. The species was collected at altimontane elevations of 4270–4400 m a.s.l. in the alpine zone on Mount Wilhelm and Mount Giluwe in the Bismarck Range in Papua New Guinea. The diagnostic characters that distinguish it from the similar R. lanuginosum are discussed and illustrated and its global distribution is reviewed and mapped. Southern cool-adapted moss species penetrating into the tropical mountains are briefly considered.
