This is doubtlessly a Mischocarpus in the 'pentapetalus-group', probably closest related to M. largifolius and M. paradoxus. It may be a new species, but the specimen may also be a hybrid, because of the sterile fruits, either between M. largifolius and M. paradoxus, or between M. sundaicus and one of the latter two species.
