The first classification for the genus Ormosia was proposed by Bentham. It was
followed by Taubert (1892) in Engler and Prantl’s Nat. Pflanzenf., who divided the genus
into 2 sections. On the basis of the pod structure and seed characters Prain (1900) arran-
ged the genus in 2 sections with 4 subsections. In the monograph on the genus Merrill
and L. Chen ( 1943 ) limited their taxonomic study to Chinese and Indo-Chinese species, and
recognized 34 species and 15 series. Recently Yakovlev (1971-1976) has treated the ge-
nus in 6 separate genera.
In the present paper the author recognizes 35 species, of which 7 species and 2 varie-
ties are new. The Chinese species of the genus are grouped into 3 sections and 6 series inmy classification. 相似文献

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.
