Peninsular Thailand; Malesia: Malay Peninsula (Kedah, Perak, Trengganu, Pahang, Selangor, Negri Sembilan and Johore).
The pollen of the present species is illustrated by Saunders ( I.c.). The Illicium species from the Malay Peninsula have been the source of considerable confusion due to their initial identification as I. cambodianum. This is discussed by Saunders ( I.c.), as is the validity of the infraspecific classification proposed by Smith ( I.c.).
