Holotype : Buchhholz 1728 (ILL.) (de Laubenfels 1972).
Dacrydium × suprinii Nimsch 2007 is a natural hybrid between this species and D. araucarioides.
"Small, erect shrub 1-2 m in height. Bark with small dark scales, fibrous, brown inside, at first, covered with many small lenticels, then develops with age many small crevices. Densely branched. Leaves becoming very dense and less spread out with age but not at all reduced in size, sharp, acicular and slightly compressed, imbricate, dense, 13-17 by 1 mm. Pollen cone terminal and lateral, the lateral ones are much smaller at the base below the terminal ones, 8-14 mm long, tapering off from the base. Microsporophylls lanceolate, long, pointed, 5 mm wide at the base of the male cone, 2 mm wide at the apex. Seed cone terminal, sometimes on very short lateral shoots, bracts resemble non-modified leaves, slightly reduced. Seed, up to 5 seeds per cone, subterminal, oval, much larger than thick, with lateral carina, rounded apex with projecting microsporophylls, 4.5 mm long, becoming almost erect, the bracts are exserted which surround the seeds." (de Laubenfels 1972).
New Caledonia, where it "can only be found within a few kilometers along the river Madeleine (Riviére des Lacs) and along the riverbanks of Lac en Huit in New Caledonia, in which the river flows" (de Laubenfels 1972).The IUCN reports that this taxon is critically endangered,facing an extremely high risk of extinction in the wild. It has an extremely restricted range of less than 100 km2 that is severely fragmented or known to exist at only a single location, and that is suffering a continuing decline in extent and/or quality of habitat and in the number of mature individuals. The total population size numbers fewer than 250 mature individuals and is continuing to decline, with no subpopulation estimated to contain more than 50 mature individuals.
De Laubenfels (1972) reports collections from the following sites:
"Dacrydium guillauminii is clearly a very distinct species and one of the rarest conifers in the world. In general morphological terms, it is related to D. beccarii Parlatore from Malaysia and the Solomon Islands" (de Laubenfels 1972).

Abstract: During excursions in New Caledonia in 1994, a hitherto undescribed natural hybrid between Dacrydium araucarioides Brongn. et Gris. and Dacrydium guillauminii J. Buchholz was found, for which the name Dacrydium × suprinii Nimsch sp. nova in honor of Bernard Suprin, Noumea, New Caledonia, is proposed. Morphological and site characteristics are presented.
