Ainsliaea macroclinidioides is a polymorphic species, with leaf blades varying from ovate-lanceolate with base rounded, apex long acuminate, and margin dentate (in the type specimen from Taiwan) to leaf blades ovate to deltate with base rounded to deeply cordate, apex acuminate, and margin dentate to obscurely dentate (in specimens from the Ryukyu Islands, Japan). Specimens from SE China with entire leaf margins that have been determined as A. macroclinidioides are referred in the present treatment to A. kawakamii.

Forests along stream banks; 500-2000 m. Taiwan [Japan].
