Abstract

<p>Desmodiastrum of the tribe Desmodieae (Leguminosae) is regarded as synonymous with Alysicarpus, or as a distinct genus related to Alysicarpus and Desmodium. To determine its systematic position, updated phylogenetic trees of the Desmodium group of tribe Desmodieae are obtained as the results of the analyses of cpDNA and nrDNA. Desmodiastrum is placed in an independent clade (Desmodiastrum clade) with Codariocalyx, Eleiotis and Leptodesmia, which is remarkably remote from the Alysicarpus and Desmodium clades. The member of the Desmodiastrum clade shares dimorphic or trimorphic leaves and drepaniform keel petals with a small lamellate appendage connecting the covered wings. Among them Desmodiastrum is supported in its distinctive systematic position by the syncolporate pollen grains. Desmodiastrum is recognized as an independent genus distinct from Alysicarpus.</p>
