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： Australian Systematic Botany is an international journal devoted to the systematics, taxonomy, and related aspects of biogeography and evolution of all algae, fungi and plants, including fossils. Descriptive taxonomic papers should normally constitute a comprehensive treatment of a group. Short papers on individual species and nomenclatural papers must contain significant new information of broader interest to be considered. The prestigious L.A.S. Johnson Review Series is published. Other review articles will also be considered. All papers are peer reviewed. Australian Systematic Botany is published with the endorsement of the Commonwealth Scientific and Industrial Research Organisation (CSIRO) and the Australian Academy of Science.
