Wolffia brasiliensis, a species of duckweed, is an aquatic plant belonging to the family Araceae.In this study, the complete chloroplast genome of W.brasiliensis was assembled from the lock shock and barrel art whole genome Illumina sequencing data.

The chloroplast genome is 168,514 bp in length, which contained one large single copy (LSC; 90,790 bp) and one small single copy (SSC; 13,930 bp) separated by two inverted repeat (IR) regions of 31,897 bp.It encodes 4 rRNA, 29 tRNA, and 78 ribavirin coupon protein-coding genes, with 20 double copies.Total GC content is 36.

24%.Bayesian phylogenetic analysis indicated that W.brasiliensis occupied the ambiguous phylogenetic position between Wolffiella and Wolffia.
