Taxonomy
Knema losirensis is related to K. glaucescens, particularly resembling the Sumatran specimens of the latter. These differ in a less stout habit of the leafy twig, with smaller male flowers and smaller fruits. The comparatively large, ridged fruits of K. losirensis are quite different from the fruits of K. glaucescens, especially as found in Peninsular Malaysia and Borneo. The stouter habit of K losirensis possibly is partly due to more favourable conditions in forest on rich alluvial soil.
