The discovery of a representative of the genus Oreomyrrhis Endlicher on Mount Kinabalu, the highest mountain in the Malayan region outside of New Guinea, adds another species to the rather remarkable list of plants now known from that mountain which must be considered as Australian types. It is, moreover, the first representative of this small genus to be found in the Malayan region, or for that matter in the Old World north of Australia. Other Kinabalu species indicating unmistakable Australian or Australian-New Zealand alliances include Blechnum fraseri Luerss., Ranunculus lowii Stapf, Drimys piperita Hook. f., Didiscus saniculaefolius (Stapf) Merr., Coprosma crassicaulis Stapf, C. hookeri Stapf, Nertera depressa Banks, Lagenophora gibbsiae Merr., Gaultheria borneensis Stapf, Euphrasia borneensis Stapf, Drapetes ericoides Hook. f., Patersonia lowii Stapf, P. borneensis Stapf, Centrolepis kanibaluensis Gibbs, Scirpus inundatus Spreng., Schoenus kinabaluensis Stapf, and S. melancostachyus R. Br. Representatives of all the characteristically Australian genera of the above list, with the exception of Coprosma and Drapetes, and of Oreomyrrhis, have been found in the Philippines, but no representatives of the genera Schoenus, Drimys, Didiscus, Drapetes, Patersonia, Centrolepis, or Oreomyrrhis have been found in western Malaya, although some have been found in Celebes and in New Guinea, a distribution wholly to be expected of all of them.
