Description

"Small tree, 2-12 m tall. Juvenile leaves spreading widely, slightly curved forward towards the apiculate tip, at least 12 mm long, slightly wider than thick. Adult leaves robust, the acute tip bent to be parallel to the branch or even curved slightly inward, crowded, linear or linear-lanceolate, 5-8 mm long, concave on the axial side, strongly keeled on the dorsal side, 0.8 to at least 1 mm wide, 0.2-0.3 mm thick. Fertile structures terminal, often on a short lateral branch. Pollen cones 20-25 mm long and 4.5-7 mm diam.; microsporophyll lanceolate, 5-6 mm long, 1.5 mm wide at the base. Seed-bearing structure consisting of bracts slightly narrower than ordinary foliage leaves and increasing slightly in length towards the apex where one or two may be fertile, spreading slightly and completely covering the epimatium but surpassed by the apex of the mature seed which is 4.5 mm long" (de Laubenfels 1988).
