Included here are the forests of the Fiji Islands (such as Viti Levu and Vanua Levu), Samoa Islands, Tonga Islands, Horn Islands, Rotuma Islands, Uvea Island and Niue Island.

Although these forests have an affinity with the dipterocarp forests of the Indo-Malayan region they lack both their stature and species-richness, but in this respect they are typical of Pacific island rain forests. They range in height from about 6-15 m but occasionally have emergents reaching up to 35 m. On Tutuila in the Samoan Islands they are dominated by the endemic Dysoxylum maota (Meliaceae) and Planchonella samoensis (Sapotaceae). Other significant trees include Bischofia javonica, Canango odorata, Ficus scabra, Kleinhovia hospita, Inocarpus fagifer, Myristica fatua and the endemic Canarium vitiense (Burseraceae), Elaeocarpus ulianus (Elaeocarpaceae) and Macaranga stipulosa (Euphorbiaceae). The forest floor is generally open and dominated by shade-tolerant ferns such as Arthropteris repen and the endemic Lomagramma cordipinna (Lomariopsidaceae). Epiphytes are abundant with Aplenium nidus being the most common species, but there are many other ferns and orchids such as Dendrobium dactylodes. Likewise lianas are also common. Hoya pottsii and the endemic Alyxia bracteolosa (Apocynaceae) and Gynochtodos epiphytica (Rubiaceae) are the most typical species.

In coastal forest, such as on Matapai Point, the endemic Diospyros samoensis (Meliaceae) becomes the main species, while other endemic taxa found here include Diospyros elliptica (Meliaceae), Planchonella garberi (Sapotaceae), Sterculia fanaiho (sterculiaceae), Syzygium dealatum (Myrtaceae) and the fern Tectaria stearnsii (Aspidiaceae).  The principal trees in Fiji include Agathis macrophylla, Burckella parvifolia, Calophyllum neo-ebudicum, Endiandra gillespiei, Myristica micrantha, Planchonella lingensis, Syzygium effusum and the endemic Canarium vitiense (Burseraceae), Degeneria vitiensis (Degeneriaceae), Dysoxylum richei (Meliaceae), Endospermum macrophyllum (Euphorbiaceae), Flacourtia vitiensis (Flacourtiaceae), Garcinia myrtifolia (Clusiaceae), Neuburgia alata (Loganiaceae) and Pandanus joskei (Pandanaceae). Shrub and ground layer species typically include Crossostylis richii, Pittosporum rhytidocarpon, Selaginella breyniodes, Streblus pendulinus, and endemics such as the palm Balaka macrocarpa (Arecaceae), the mega herb Alpinia baia (Zingiberaceae) and the saprophytic herb Andruris vitiensis (Triuridaceae). Other endemic species recorded for these forests include Acanthephippium vitiense (Orchidaceae), Airosperma trichotomum, Ixora maxima, Readea membranacea, Squamellaria imberbis, Xanthophytum calycinum (Asteraceae), Aristolochia vitensis (Aristolochiaceae), Astronidium floribundum (Melastomataceae), Burckella fijiensis (Sapotaceae), Connarus pickeringii (Connaraceae), Firmiana diversifolia (Sterculiaceae), Flagellaria gigantea (Flagellariaceae), Freycinetia caudata (Pandanaceae), Geniostoma macrophyllum (Loganiaceae), Gonostylus punctatum (Gonystylaceae), Ilex vitiensis (Aquifoliaceae), Orthiopteris tenuis (Pteridaceae), Podocarpus descipiens (Podocarpaceae), Saurauia rubicunda (Saurauiaceae) and Syzygium amplifoliaceae (Myrtaceae).
