Knema laurina may be confused with other species, e.g. K. pseudolaurina and K conferta, with persistent indumentum on the lower leaf surface. Knema pseudolaurina has mainly sessile stellate hairs. Knema conferta differs essentially in the shape of the male buds, and by the dark dots on the lower leaf surface.
