KERUING 
          Keruing
                is produced by numerous species of Dipterocarpus, the more common
                of which are D.apterus, D.baudii, D.chartaceus, D.concavus, D.costatus,
                D.crinitus, D.dyeri, D.gracilis, D.cornutus, D.costulatus, D.grandiflorus,
                D.kerrii, D.sublamellatus, D.kunstleri, D.lowii, D.obtusifolius,
                D.rotundifolius, D.verrucosus, D.acutangulus, D.applanatus, D.caudiferus
                and D.confertus. The timber generally seasons well with some
                end-splitting and surface checking as the main defects.
