Leaves broadly ovate, 14-22 cm ⊙ 10-16 cm, base obtuse or subcordate, apex obtuse or subacute, prominently plicate, crenate in the distal half, secondary veins 14-20 pairs, ascending, petiole 2.5-4 cm long, stipules lorate, obtuse, outside tomentose. Stamens about 30. Fruit calyx tube subglobose, smooth, glabrescent, 2 larger fruit calyx lobes up to 15 cm ⊙ 3 cm, 3 shorter ones up to 15 mm ⊙ 10 mm. D. obtusifolius is a characteristic and frequently gregarious, fire-resistant tree in dry dipterocarp or bamboo forest. In Indo-China a glabrous form is distinguished and called var. subnudus Ryan & Kerr. The density of the wood is 750-900 kg/m3 at 15% moisture content. A natural hybrid between D. obtusifolius and D. costatus has been observed in Thailand and Burma. | |
