Abstract:The achene of Elatostemais 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 ob-
servations,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.
Key words:Urticaceae;Elatostema;achenes;supplementary description
  The genus ElatostemaJ.R.Forst.&G.Forst.be-
longs to Urticaceae,with about 500species distributed
in tropical and subtropical regions of Africa,Asia and
Oceania;approximately 234species,in which probably
205endemic species,occur in China,particularly in
south of the Qinling Mountain(Wang,1995,2012).Re-
cently,several new taxa of this genus have been de-
scribed(e.g.Wang,2010a,b,2011;Wang & Wei,
2007;Wei & Wang,2009;Wu et al.,2011a,b).Taxo-
nomicaly,the morphology of achenes in Elatostemais
used as one of the important characters for delimiting
series,and also is helpful in the study of evolution-
ary trends in infra-generic taxa of Elatostema.So
far,seven types of achene have been recognized as:
(1)ribbed,(2)ribbed and tuberculate,(3)tubercu-
late,(4)tuberculate and reticulate-striate,(5)
puncticulate,(6)smooth,and(7)smooth and
winged,and(8)lineolate(Wang,2012).
In this paper,supplementary description of a-
chenes of seven species are herein given and ilustrated.
