Abstract

Sauropus elachophyllus (F.Muell. ex Benth.) Airy Shaw and S. rigidulus (F.Muell. ex Müll.Arg.) Airy Shaw are revised under the reinstated genus Synostemon F.Muell. (Phyllanthaceae) using morphological and nrITS sequence data. Sauropus decrescentifolius J.T.Hunter & J.J.Bruhl and S. elachophyllus are shown to be conspecific as Synostemon elachophyllus (F.Muell. ex Benth.) I.Telford & Pruesapan and S. elachophyllus subsp. decrescentifolius (J.T.Hunter & J.J.Bruhl) I.Telford & Pruesapan, with Synostemon elachophyllus subsp. latior (Airy Shaw) I.Telford & Pruesapan (syn. Sauropus elachophyllus var. glaber Airy Shaw p.p.) raised in rank. The ‘Top End clade’ has morphological synapomorphies of fused staminal filaments and connectives, and linear, longitudinal anthers. Four new species are named: Synostemon cowiei I.Telford & J.J.Bruhl, S. inaequisepalus I.Telford & J.J.Bruhl, S. kakadu I.Telford & J.J.Bruhl and S. nitmiluk I.Telford & J.J.Bruhl and new combinations are provided: S. crassifolius (Müll.Arg.) I.Telford & Pruesapan, S. ditassoides (Müll.Arg.) I.Telford & Pruesapan, S. dunlopii (J.T.Hunter & J.J.Bruhl) I.Telford & Pruesapan, S. filicinus (J.T.Hunter & J.J.Bruhl) I.Telford & Pruesapan, S. gracilis (J.T.Hunter & J.J.Bruhl) I.Telford & Pruesapan, S. rigidulus (F.Muell. ex Müll.Arg.) I.Telford & Pruesapan, and S. stenocladus (S.Moore) I.Telford & Pruesapan, with S. pinifolius (J.T.Hunter & J.J.Bruhl) I.Telford & Pruesapan also raised in rank.

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
