Taxonomic notes

Description

"Tree 10-17 m tall, 25-30 cm diam., with drooping twigs. Leaves linear, straight, spread out more or less perpendicular to the shoot except on new growth, narrowing abruptly at the apex to an apiculate tip, flat on the upper surface but becoming slightly concave towards the apex, stomata on the upper surface in two bands separated over the midvein, sharply keeled on the lower surface, 5-10 mm long, 0.7-1 mm wide, 0.2 mm thick. Fertile structures usually lateral, subtended by a cluster of reduced leaves which are 2-3 mm long. Pollen cones 7-10 mm long and 2-2.5 mm diam. Apex of the microsporophyll a lanceolate spur c. 1 mm long and 0.7 mm wide. Seed bracts 3-4 mm long with sometimes two fertile. Mature seed unknown" (de Laubenfels 1988).

Remarks

"The spreading straight linear leaves contrast rather strikingly with other members of the genus and rather resemble the juvenile foliage of Cupressaceae. Earlier I had included it in D. spathoides where the shorter leaves are also more or less linear and much wider than thick, but in this species the fertile structures are usually terminal and are subtended by nearly typical leaves not greatly reduced as in D. ericoides, while the leaves are distinctly bent forward and not straight" (de Laubenfels 1988).
