Abstract: The genus Limonium, commonly known as Sea Lavenders, is one of the most species-rich genera of the family Plumbaginaceae. In this study, two new plastomes for the genus Limonium, viz. L. tetragonum and L. bicolor, were sequenced and compared to available Limonium plastomes, viz. L. aureum and L. tenellum, to understand the gene content and structural variations within the family. The loss of the rpl16 intron and pseudogenisation of rpl23 was observed. This study reports, for the first time, expansion of the IRs to include the ycf1 gene in Limonium plastomes, incongruent with previous studies. Two positively selected genes, viz. ndhF and ycf2, were identified. Furthermore, putative barcodes are proposed for the genus, based on the nucleotide diversity of four Limonium plastomes.
