Knema mogeana may be confused with K. hirtella, K. stenophylla, and K subhirtella. Knema stenophylla has more equal-sized minute hairs on the lower leaf surface, and larger male buds; K. hirtella and K subhirtella both differ in stouter habit, leaves more prominently reticulate above, androphore often minutely pubescent at base, more anthers, 8—13(—15), and larger fruits. In K subhirtella the bracteoles are late caducous and the perianth is cleft less deeply.
