Discussion

  • D. draco was collected in Sarawak in a valley bottom in lowland dipterocarp forest at 50 m altitude. This specific name has been applied in several senses; Beccari's interpretation (Beccari 1911) is followed here. D. draco approaches D. micracantha but the leaf sheath spines are more robust and the leaflets fewer and larger; the inflorescence bracts of D. draco are also very much thicker than those of D. micracantha.
