We investigate the evolution and systematics of the poorly studied Mesoamerican and South American polyploid broad-leaved Festuca L. species of uncertain origin and unclear taxonomy. A taxonomic study of seven diagnostic morphological traits was conducted on a representation of 22 species. Phylogenomic analyses were performed on a representation of these supraspecific taxa and all other Loliinae lineages using separate data from the entire plastome, nuclear rDNA 45S and 5S genes, and repetitive DNA elements. F. subgen. Mallopetalon falls within the fine-leaved (FL) Loliinae clade, whereas the remaining taxa are nested within the broad-leaved (BL) Loliinae clade forming two separate Mexico–Central–South American (MCSAI, MCSAII) lineages. MCSAI includes representatives of F. sect. Glabricarpae and F. subgen. Asperifolia plus F. superba, and MCSAII of F. subgen. Erosiflorae and F. sect. Ruprechtia plus F. argentina. MCSAII likely had a BL Leucopoa paternal ancestor, MCSAI and MCSAII a BL Meso-South American maternal ancestor, and Mallopetalon FL, American I–II ancestors. Plastome vs. nuclear topological discordances corroborated the hybrid allopolyploid origins of these taxa, some of which probably originated from Northern Hemisphere ancestors. The observed data indicate rapid reticulate radiations in the Central–South American subcontinent. Our systematic study supports the reclassification of some studied taxa in different supraspecific Festuca ranks. 000119737 536__ $$9info:eu-repo/grantAgreement/ES/DGA-FSE/A01_17R$$9info:eu-repo/grantAgreement/ES/DGA/LMP82-21$$9info:eu-repo/grantAgreement/EUR/ERASMUS/2019-1-ES01-KA107-062605 000119737 540__ $$9info:eu-repo/semantics/openAccess$$aby$$uhttp://creativecommons.org/licenses/by/3.0/es/ 000119737 590__ $$a4.5$$b2022 000119737 592__ $$a0.79$$b2022 000119737 591__ $$aPLANT SCIENCES$$b43 / 239 = 0.18$$c2022$$dQ1$$eT1 000119737 593__ $$aEcology$$c2022$$dQ1 000119737 593__ $$aPlant Science$$c2022$$dQ1 000119737 593__ $$aEcology, Evolution, Behavior and Systematics$$c2022$$dQ1 000119737 594__ $$a5.4$$b2022 000119737 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/publishedVersion 000119737 700__ $$0(orcid)0000-0002-1214-375X$$aInda, Luís.
