Knema conferta is a homogeneous species which, in the vegetative state, may be confused with K. laurina, K. oblongata, K. scortechinii, or K. pubiflora, all different in details of male flowers and indumentum; K. pubiflora is similar in the dotted lower leaf surface with almost identical indumentum, but the perianth is hairy inside. The fruits are variable, in size as well as in shape. They are more or less ellipsoid, but some specimens from Nunukan Is. and the Leila Forest Reserve (Sabah) differ by their nearly globose fruits, 2.5-3.5 cm in diameter, with conspicuously thick (4-5 mm) dry pericarp.
