Abstract: Taxonomically revised in this paper are Chloranthus henryi Hemsl. and its allies on the basis of character analysis and type examination. Four species, i.e.C. serratus (Thunb.) Roem. et Schult., C. henryi, C. sessilifolius K. F. Wu and C. oldhami Solms-Laub., are recognized. C. monostachys R. Br., C. hupehensis Pamp. and C. serratus var. taiwanensis K. F. Wu are reduced as new synonyms of C. serratus, C. henryi and C. oldhami, respectively. As C. philippinensis Merr. and C. verticillatus Merr. are found to be more similar to C. oldhami than to C. henryi, they are both treated as conspecific with C. oldhami rather than with C. henryi. After a careful examination of the syntypes and their photos of C. henryi, C. multistachys P' ei and C.hupehensis, lectotypes of these names are designated.
