Evergreen broad-leaved forests; low to medium elevations. Taiwan [Japan].

Liu (Woody Fl. Taiwan, 155. 1972) recorded this species from the forest of Congaing, Yong’an, Fujian Province, at 700 m, but the specimen has not been seen by the present authors.

This species and Actinodaphne mushaensis have been treated under both Actinodaphne and Litsea. However, based on the number and imbricate arrangement of their involucral bracts, they do not belong to Litsea and so are retained here under Actinodaphne.

The wood is used for construction and furniture.
