Abstract

We demonstrate the high value of the inflorescence and achene for taxon delimitation in Elatostema. Over half of the descriptions of the ca 280 species described from China, however, lack information on inflorescence and/or achene morphology and this hampers the progress of species discovery and infrageneric classification. In this paper we supplement the descriptions, illustrations and photos of infructescence and achene of Elatostema binatum and staminate inflorescence of E. fengshanense in order to support future taxonomic revisions of this species-rich genus. In addition, we assessed the extinction threat of these species.
