Taxonomy
A complex species, in which three forms are distinguished. The species as a whole seems closest related to K. latericia and K. furfuracea, both with longer male flower pedicels. Knema latericia has thinner twigs, less coriaceous leaves and smaller male flowers, with a different androecium. Also K. lunduensis is related; for differences see under that species.
