mesophyll vine forests dominated by fan palm Licuala ramsayi (commonly known as licuala palm)
mesophyll vine forests dominated by feather palm Archontophoenix alexandrae (commonly known as Alexandra palm).
Fan palm wetlands are slow growing, with fan palms reaching up to 20 m. Fan palms constitute only up to 20% of the total number of stems in any site, and these are predominantly mature trees rather than seedlings, since fan palms have low seedling numbers with commonly only 50 to 500 per hectare. There is greater plant species diversity in fan palm swamps than in the feather palm swamp wetlands. Of these, 60% are trees, with around 20 species present in most fan palm swamp wetlands and in adjacent vine forest and swamp forest types. The fan palm swamp wetlands also host a variety of shrubs, vines, epiphytes and herbs.
Feather palms grow to approximately 20 m tall and can dominate swamp wetland habitats, with up to 150 000 stems per hectare in some sites. Seedling palms form up to 95% of the total number of palm stems. The feather palm swamp has freshwater mangrove Barringtonia racemosa as a commonly occurring canopy species. Also present may be yellow penda Ristantia pachysperma, macaranga Macaranga polyadenia, or river cherry Syzygium tierneyanum.
The second feather palm swamp wetland type contains species that are shared with adjacent mesophyll vine forests such as northern silky oak Cardwellia sublimis, Beilschmiedia brunnea, cluster fig Ficus racemosa, white fig F. virens, and Ilex arnhemensis.
Most species in the palm swamp wetlands are relatively widespread in other forest types beyond the feather palm swamp wetlands, and often reflect the species composition of neighbouring rainforest communities.
Palm swamp wetlands provide habitat for rare and threatened flora such as the endangered blue tassel fern Huperzia dalhousieana.
