Papuan Swamp Forest

The forests of permanent swamps are generally open and have a varied range of heights. Much of them are composed of a mixture of trees such as Alstonia scholaris, Bischofia javanica and the endemic Terminalia canaliculata (Combretaceae). Other areas can be described as pandan swamp, in which Pandanus species predominate; sago palm (Metroxylon sagu) swamp, which may include the endemic Aceratium sinuatum (Elaeocarpaceae); Campnopermum swamp, in which Campnospermum brevipetiolata often dominates; Terminalia swamp, in which Terminalia brassii is the main species and finally Melaleuca swamp usually dominated by Melaleuca cajuputi. Other endemic trees of these forests include Aglaia lepidopetalum (Meliaceae), Calophyllum suberosum (Hypericaceae), Cupaniopsis bilocularis (Sapindaceae), Dacrydium cornwalliana (Podocarpaceae), Dysoxylum brevipaniculum (Meliaceae), Elaeocarpus branderhorstii (Elaeocarpaceae), Gomphandra pallida, Pseudobotrys dorae, Rhyticaryum macrocarpum (Icacinaceae), Horsfieldia pulverulenta, Myristica inundata, Paramyristica sepicana (Myristicaceae), Lepidopetalum micans (Sapindaceae), Maniltoa brassii (Caesalpiniaceae) and Terminalia sogerensis (Combretaceae). Smaller palms, pandans, and shrubs often fill in much of the spaces below the canopy. Among the endemic shrubs and small tree are Harpullia rhachiptera (Sapindaceae), Neuburgia rumphiana (Loganiaceae) and Rhododendron angulatum (Ericaceae), while the ground layer typically includes tall sedges such as the endemic Capitularina involucrata (Cyperaceae) and ferns. There are also a great variety of climbing plants such as the endemic Chlaenandra ovata (Menispermaceae) and a number of epiphytic shrubs like the endemic Vaccinium kostermansii (Ericaceae).
