Description
"Shrub of 1 m or a small, often gnarled tree, sometimes up to 20 m tall. Densely branched to form a compact oval shape. Juvenile leaves spreading widely but sometimes distinctly curved forward so that the apiculate apex is more or less parallel to the branch, lanceolate, up to 20 mm long, strongly keeled on three sides, nearly flat on the axial surface, up to 0.6 mm wide, 0.3 mm thick. Adult leaves on younger trees nearly straight and up to 8 mm long but with greater age the leaves become shorter and sharply curved forward or even slightly inward, apiculate, linear-lanceolate, 3-6 mm long but nearly uniform on a branch, 0.5-0.6 mm wide, 0.3 mm thick. Fertile structures mostly terminal. Pollen cones with basal leaves hardly different from foliage leaves, 7-9 mm long, 2.5 mm diam. Apex of the microsporophyll a linear-lanceolate spur 1.5-2 by 0.5 mm with the broadly acute apex strongly curved inwards so as to appear rounded and blunt. Seed-bearing structure subtended by a zone of reduced leaves about 2 mm long, the cone bracts longer and partly covering the seed. The brown seeds about 5 mm long" (1).Range
"Malaya (G. Tahan complex) and N. Sumatra (Gajo Lands: G. Leuser & Bandahara)... Rising above and often dominant in low mountain scrub on what appears to be rather poor soils between 960 and 2100 m in Malaya and 1800-2600 m in Sumatra; not rarely associated with Baeckea and Leptospermum" (1).Big Tree

Remarks
"The shortest leaved specimens resemble D. pectinatum foliage, a species which grows under similar conditions at lower elevations, but the fertile material more closely resembles several other species" (1).Citations
