Mou (Silba 1986).
"Tree, heavily branched, reaching heights of 25 m or occasionally more. Bark in brown layers, fibrous and light colored inside, the surface more or less smooth and covered in many small lenticels. Juvenile leaves acicular, very thin, 10 mm long, gradually becoming adult leaves. Adult leaves flat, lanceolate, slight keeled on the dorsal side with a clear ridge on the axial side, thorny, spreading out and curved so that the apices are parallel with the branch, 3-4.5 mm by 0.7-0.8 mm. Pollen cone terminal and often also lateral at the base of a terminal pollen cone, cylindrical, 4-7 mm long and 1.2 mm in diameter. Microsporophylls triangular, slightly longish, sharp and imbricate. Seed cone terminal, often on a short shoot, leaves just below the seed cone very small compared to normal leaves, sometimes only 1 mm long. Cone bracts very large and partially covering the epimatium, normally only 1 fertile bract. Seed partially erect and completely visible, a shiny chocolate brown, oval and tapering off to a blunt point, 3-3.5 mm long" (de Laubenfels 1972).
New Caledonia: At elevations of 900-1400 m in "ombrophilous forests on the southern part of the main island" (de Laubenfels 1972). Within its range, mean annual temperature is 19.0°C, with an average minimum in the coldest month of 12.4°C, and a mean annual precipitation of 1899 mm (Biffin et al. 2011, Table S5).
Collections are recorded from the following locales (de Laubenfels 1972):
The IUCN reports that the population status is stable.
"No other species is closely affiliated with D. lycopodioides but in general resembles in appearance other New Caledonian conifers. Dacrydium spathoides from New Guinea is somewhat related to this species by also having flattened leaves" (de Laubenfels 1972).
