Abstract:

The achene of Elatostema is one of the important morphological characters for delimiting infra-generic series and species,while it is significant for understanding the evolutionary relationship in Elatostema. In this paper,based on careful examinations of achenes from several voucher specimens including type,consulting literature and field observations,the descriptions of achenes of seven Chinese species in this genus are presented,this would provide some valuable information for further taxonomic revision of Elatostema.
