Malesia: Borneo (N Sabah, Penampang Distr.); known only from the type collection; see note.
The specimen on which the present subspecies has been based represents an exceptionally stout plant. The distinction with subsp. tridactyla may prove to be problematic, but the type of K. tridactyla, with slenderly branched male inflorescences and small flowers (perianth 1.5 mm diam., 6 or 7 anthers), is quite different.
