Forest remnants were composed of Dacrydium

Gymnosperm taxa represented by both leaves and pollen comprise at least eight conifers including Dacrycarpus, Dacrydium, Halocarpus, Microcachrys, Podocarpus and Phyllocladus (Jordan et al.
Foliage and wood preserved at Newvale indicate a diverse range of podocarps including Dacrycarpus, Dacrydium, Halocarpus, Microcachrys, Phyllocladus, Podocarpus, and Agathis.
The total pollen component comprises traces of Dacrydium

Long-lived conifers such as Agathis australis (Araucariaceae), Dacrydium cupressinum (Podocarpaceae), and Prumnopitys taxifolia (Podocarpaceae) typically have strongly discontinuous age structures in old-growth stands, consistent with regeneration in response to infrequent large-scale disturbance events.
These were, in order of decreasing basal area, Nothofagus menziesii (Fagaceae), Weinmannia racemosa (Cunoniaceae), Dacrydium cupressinum (Podocarpaceae), and Prumnopitys ferruginea (Podocarpaceae).

Woody plants included species of Acacia, Athrotaxis, Areca, Brachychiton, Caryota, Cocos, Callitris, Casuarina, Dacrydium

One legacy from this past is that some conifer genera, such as Araucaria, Dacrydium
, Podocarpus and Agathis, still occur in lowland rainforest, sometimes in extensive stands.
The montane tree Nothofagus is important throughout the record, though other trees, including Castanopsis/Lithocarpus, Myrtaceae, Dacrydium
and Pandanus attain dominance at different times.

The montane forests of southeastern Asia also produce valuable timber from conifers of the genera Podocarpus and Dacrydium
Three species of Dacrydium - 2n = 18 (14 M + 4 t), 2n = 22 (10 M + 12 t), and 2n = 24 (8 M + 16 t) - fell into another group with NF = 32, and three Phyllocladus species were all 2n = 18 M, NF = 36.
At the other extreme, the karyotype of Dacrydium laxifolium designated V chromosomes which seem to include M and sm types are amongst the smallest members of the complement, while the I chromosomes include t or T types of widely varying length but most being three to four times the length of any metacentric.
