Taxonomy
Knema kostermansiana may resemble K. glauca and K. pulchra. Knema glauca differs in its shorter fruits, and median bracteole, narrower leaves, and ± raised nerves; K. pulchra is distinguishable by pear-shaped, not globose, male buds and by much broader ellipsoid fruits with rounded apex. The slender, ± fusiform fruits of 7 cm length of K. kostermansiana much resemble those of K. luteola, and somewhat those of K. ashtonii var. ashtonii; both differ in a much finer venation on the upper leaf surface, the first by narrow-rounded or attenuate leaf base and generally somewhat smaller fruits (up to 70 mm long), the second in stouter habit and the fruits with ± blunt apex, not pointed.
