Neomicrocalamus and Temochloa are closely related to bamboo genera. However, when considered with newly discovered morphologically similar material from China Vietnam, the phylogenetic relationship among these three groups was ambiguous in analyses based on DNA regions. Here, as a means of investigating relationships exploring potential sources genomic conflicts, we present phylogenomic examination whole plastome, single-nucleotide polymorphism (SNP), single-copy nuclear (SCN) gene datasets. Three different hypotheses were found. The inconsistency is attributed combination incomplete lineage sorting introgression. origin bamboos introgressive hybridization between liliana (which contributed 80.7% genome) prainii (19.3%), indicating that closer T. genetics. more morphology distribution elevation also imply bamboos.
