Rorippadaguanensis (Brassicaceae), a new species from eastern China.

Abstract

Rorippadaguanensis W.Zhang & K.Zhao (Brassicaceae), a new species from Anhui and Hubei Provinces of eastern China, is described. Its floral morphology resembles R.dubia, with its fruit morphology similar to R.cantoniensis. However, it can be readily distinguished from R.dubia by its inconspicuous stems, oval silicle and from R.cantoniensis 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 Rorippa species, revealed that R.daguanensis is sister to R.cantoniensis.
