ABSTRACT Feralization, the re‐establishment of wild populations from domesticated ancestors, can involve multiple parallel character reversions and potentially also rampant gene flow with cultivated and/or naturally material. It hence poses great challenges for infraspecific classification, which may impede crop development, but studies on these issues are rare. Ramie ( Boehmeria nivea ; Urticaceae) is an important fiber worldwide. has been traditionally divided into 2–4 varieties, controversial. Here, 78 feral individuals were sampled 12 Chinese provinces, plus 11 farmland. We employed integrative taxonomy approach combining lines evidence morphology, phylogenomics, ecology to investigate intraspecific subdivision B. . A chi‐square test qualitative morphological characters significantly distinguished three varieties within : var. , tenacissima recently described strigosa comprising mainly cultivated, feralized, only material, respectively. The PCoA random forest analyses indicated differences between other two varieties. However, quantitative could not distinguish None was monophyletic based phylogeny plastome data, whereas weakly supported as nuclear ribosomal DNA (18S‐ITS1‐5.8S‐ITS2‐26S). Ecological niche modeling showed overlap potential distribution areas neither overlapped These collectively demonstrate distinctiveness mostly did fully separate Hence, a biologically meaningful variety, should be synonymized results aid breeding improvement new ramie highlight value taxonomic methods in examining subdivisions species that include feralized
