(Parlatore) de Laub. 1969

Common names

Sangu [Sumatra: Gajo]; igem [Philippines: Davao, Mindanao] (de Laubenfels 1988).

Taxonomic notes

Syn: Podocarpus cumingii Parlatore 1868; Nageia cumingii (Parl.) O.K. 1891; Podocarpus imbricatus var. cumingii (Parl.) Pilger 1903 (de Laubenfels 1988).

Description

"Tree, 8-25 m tall, up to 18-75 cm diam. Leaves of primary shoots spreading slightly, often curved so that the apex is directed inward slightly towards the axis. Leaves of juvenile foliage shoots distichous, nearly linear. Leaves of older trees similar but mostly not distichous, often more robust and scarcely keeled on the lateral faces, 3-6 by 0.6-0.8 mm. In addition to primary shoots and purely foliage shoots there are intermediate shoots with leaves 2-3 mm long, strongly keeled on four sides, but distinctly bilaterally flattened. The intermediate shoots bear foliage shoots and fertile shoots but are caducous like the foliage shoots and unlike the primary shoots. Pollen cones usually normal but on one specimen from low elevation up to 4 cm long. Involucral leaves greatly elongated resembling the foliage leaves but curved, not straight, 7-13 mm long, completely surrounding the developing fertile structure which scarcely surpasses them when fully mature. Ripe receptacle reddish" (de Laubenfels 1988).

Distribution and Ecology

Widespread in the Philippines (Luzon, Negros, Panay, Mindanao); 2 collections from N Sumatra; rare in Borneo: Sarawak. It is locally common at elevations of (1000) 1850-2650 (3314) m in primary moss forest. This places it above D. imbricatus, of which most varieties do not occur in moss forest (de Laubenfels 1988).
