Abstract:

This paper deals with morphological characters in seedlings and adult plants of 5

species of Chinese Calycanthaceae. The germination of seeds, morphology of cotyledons,

hypocotyl and primary leaves of these species are enumerated, for example, the Chimon-

anthus campanulatus, sp. nov. is characterized by half-hypogaeous and tetragonal coty-

ledons, whereas other species epigaeous; the cotyledons of Calycanthus chinensis is

obtriangular, Chimonanthus praecox, Ch. salicifolius and Ch. nitens are reniform. On

the morphological characters of these adult plants and geographical distribution of 4

species of Chimonanthus are keyed. In addition a new species, Chimonanthus campa-

nulatus, is described and it represents a more primitive type of the genus.
