Leaves: Juvenile leaves are nearly straight, linear-lanceolate, becoming gradually curved forward, strongly keeled on three sides, nearly flat on the axial surface, up to 17 mm long, 0.2 mm wide and 0.1 mm thick. Adult leaves are spreading, bent slightly forward but the apiculate tips still directed slightly outward, triangular in cross section, 5-10 mm long, 0.3-0.4 mm wide, 0.2 mm thick, crowded, linear-lanceolate. Cones: Both lateral and terminal, subtended by about a dozen reduced leaves c. 1 mm long, the seed cone itself formed of a similar number of bracts up to 2 mm long and not completely covering the epimatium. There are 2(3) seeds fully exposed at the apex of the structure (1). Pollen cones: Both lateral and terminal, 7-10 × 2.5-3 mm, subtended by a cluster of sterile 1-2 mm long bracts. Apex of the microsporophyll is a lanceolate spur c. 1 × 0.3 mm (1). Seeds: Shiny, dark brown, c. 4 mm long (1). RangeSolomon Islands (Guadalcanal); New Guinea (incl. Normanby I. & New Britain); Moluccas (Taliabu); Philippines (Mindanao; Negros; Biliran I.); and (mainly W.) Borneo to Malaya and N. Sumatra. "In the eastern part of the range there are only widely separated occurrences, and even in the western part they are somewhat discontinuous... Most common on mossy ridges where it is often dominant and also found rising above a low mixed mountain scrub, from 600-2500 m. A variety of soils such as sandy peat and andesite have been indicated" (1).Big TreeOldestDendrochronologyEthnobotanyObservationsThe tree occurs in montane ericaceous forests in the Taman Negara National Park (2), which may be an excellent place to find it.RemarksCitations(1) de Laubenfels 1988.
