Abstract: This paper deals with the parallel evolution in Litsea and Lin-deria of Lauraceae which is noL only occured in the infrageneric level but also in the generic level. Lit sea and Lindera devcloped into Dodecadenia and Ite- adaphlne and evolved from Parasassafras and Sinosassafras separately. Li- tsea subg. Uniflos Yang et P. H. Huang has been reduced to the genus Do- decadenia and Litsea monantha Yang et P. H. Huang to Dodecadenia gran- diflora Nees var. grandiflora according to the type specimen. Lindera cau-data (Nees) Hook. f. has been recombinated to the genus Iteadaphne as I.caudata (Nees) H. W. Li, comb. nov. In addition, a new genus Sinosassa- fras H. W. Li has bcen cstablished from Parasassafras Long only on the basis of 2-locellate anther.
