Abstract

Cladistics analysis was carried out to find the correct phylogenetic relationship of the four genera of Calycanthaceae. Morphological and anatomical information from all aspect of the data were considered for the analysis. Siparuna guianensis (Siparunaceae) and Cinnamomum malabatrum (Lauraceae) were considered as out-group. Characters were selected mainly for reasonable argument of the similarity. Character-state transformation and discrimination of the genera were decided based upon the out-group comparison method. PAUP* (ver. 4.0) program was used for the dataset analysis and to make phylogenetic tree. The genera split into two separate genera Idiospermum + Chimonanthus and Sinocalycanthus + Calycanthus. Chimonanthus + Idiospermum are supported strict consensus tree with f-value calculation. Furthermore, Sinocalycanthus and Calycanthus are separated genera. Therefore, Calycanthaceae be redefined wide circumscriptions of the characters. The detailed investigation of the cladistics analysis revealed that the Sinocalycanthus and Calycanthus are the sole genus.
