Rorippa daguanensis (Brassicaceae), a new species from eastern China

<i>Rorippadaguanensis</i> W.Zhang & K.Zhao (Brassicaceae), a new species from Anhui and Hubei Provinces of eastern China, is described. Its floral morphology resembles <i>R.dubia</i>, with its fruit morphology similar to <i>R.cantoniensis</i>. However, it can be readily distinguished from <i>R.dubia</i> by its inconspicuous stems, oval silicle and from <i>R.cantoniensis</i> by the absence of petals and bracts on its flowers. The complete plastid genome of this new species is 155,594 bp in length. Phylogenetic analyses, based on whole plastid genome sequences of <i>Rorippa</i> species, revealed that <i>R.daguanensis</i> is sister to <i>R.cantoniensis</i>.
