Subspecies[1]
  • D. c. subsp. condorensis
  • D. c. subsp. penangianus (Foxw.) P.S.Ashton

It is an emergent tree, up to 50 m tall, in mixed dipterocarp forest on dry ridges. It is found in Sumatra, coastal Peninsular Malaysia, Singapore, and Borneo, the Philippines, and Vietnam.[1] It is a medium hardwood sold under the trade names of Keruing. It was formerly most abundant along the coastal hills on sandy soils, but is endangered due to land conversion.[3] D. condoriensis is found in at least one protected area (Sepilok Forest Reserve).

Subspecies edit

There are two accepted subspecies:[1]

  • Dipterocarpus condorensis subsp. condorensis (synonym Dipterocarpus caudatus Foxw.) – Vietnam (Con Dao) and Philippines (Luzon and Mindanao)[4]
  • Dipterocarpus condorensis subsp. penangianus (Foxw.) P.S.Ashton & Luu (synonyms Dipterocarpus caudatus subsp. penangianus (Foxw.) P.S.Ashton and Dipterocarpus penangianus Foxw.) – Peninsular Malaysia, Sumatra, and Borneo[5]

The synonymous species name caudatus is derived from Latin (caudatus = tailed) and refers to the narrow acumen of the leaf apex.[3]
