In this study, the complete plastomes of two flowering epiparasites: Phacellaria compressa and P. glomerata (Amphorogynaceae, Santalales) were sequenced. Both species possess similar size, structure, gene content, and arrangement of genes to other hemiparasites in Santalales. Their plastomes were characterized by the functional loss of plastid-encoded NAD(P)H-dehydrogenase and infA genes, which strongly coincides with the general pattern of plastome degradation observed in Santalales hemiparasites. Our study demonstrates that the shift to epiparasitism and reduced vegetative bodies in P. compressa and P. glomerata do not appear to cause any unique plastome degradation compared with their closely related hemiparasites. The epiparasitic lifestyle or an endophytic growth form observed in these two epiparasites may have limited impact on the reductive modification of their plastomes.} }
