II. Introduction [B]

B 1  Taxonomy of the species Dacrydium araucarioides BRONGN. et  GRISEB.

The species Dacrydium araucarioides was initially described in 1866, viz. in the Bull. Soc. Bot. France 13:426 and in the Ann. Sci. Nat. Paris sér. 5,6:244.
Other authors like CARRIÈRRE, PILGER, SCHINZ ET GIULLAUMIN, COMPTON, DALLIMORE ET JACKSON, DAENIKER and SARLIN followed up.

Last revisions on the genus were made by D.J. DE LAUBENFELS in 1969 and by C.J. QUINN in 1982.

B 2  Distribution

Dacrydium araucarioides is distributed in the south and east of New Caledonia from sea level up to 1000 m altitude.

B 3  Description

Dacrydium araucarioides is a small tree growing 3-7 m high.
It can be found at relatively dry habitats often characterized by the lack of ground vegetation.
Due to the overall light or open vegetation the tree can develop a round crown with a structure resembling multi-storied candelabras.

Needles of juvenile twigs are lineal, loosely and all-around upright arranged, round about 1 cm long and reddish in colour during shoot.
The color of the juvenile branchlets in the shadow is blue-green.
Needles of adult branches are very small (of a length of only 3-5 mm and of 1-1,4 mm broadness).
They resemble close-fitting, overlapping scales and are arranged in several spiralling rows.
The needle basis is stem-clasping. The branches look cylindric due to the symmetrically arranged, pricker like aged needles, which have free tips without edges.

During maturation the tips of branches with seeds get purple and succulent.
Seeds are about 3 mm long and 1–3 of them are set inside the cone, coated by the fleshy arillus.
