Knema psilantha resembles K. latericia and to a lesser extent K. furfuracea\ K latericia differs in the more depressed globose mature male flower buds, not glabrescent, with different androecium, and less conspicuously flaking, more slender twigs; K. furfuracea also has differently shaped male buds, with quite different androecium, but in that species the flowers are often glabrescent as well. Knema psilantha is well characterized by the partly glabrescent, ellipsoid, male flower buds, and only 6 or 7 conspicuously long-stiped anthers.
