Abstract The familial placements of Cyrtandromoea Zoll. and Wightia Wall., two small enigmatic South‐East Asian genera, have long been controversial in Lamiales. Here we adopt a two‐step approach to resolve their phylogenetic relationships. We initially reconstructed large‐scale phylogeny Lamiales using six chloroplast markers ( atpB , matK ndhF psbBTNH rbcL rps4 ). results showed that both emerged the LMPO clade, including Lamiaceae, Mazaceae, Phrymaceae, Paulowniaceae, Orobanchaceae. Based on second set rps16 trnL‐F ) nuclear ribosomal regions (external transcribed spacer internal spacer) for analyses focusing our revealed was consistently nested within whereas supported as sister Phrymaceae by DNA dataset or Paulowniaceae dataset. Morphological anatomical evidence fully supports inclusion an updated tribal classification is done with five tribes, is, Cyrtandromoeeae Bo Li, Bing Liu, Su Liu & Y. H. Tan, trib. nov., Diplaceae Leucocarpeae, Mimuleae, Phrymeae. conflicting position indicated different genome difficulty placing genus either Paulowniaceae. Considering distinct morphological differences between other families here propose new family, Wightiaceae fam. accommodate it, which 26th family recognized
