Agt1 exon IV + intron IV maximum likelihood tree of various accession from the Tillandsia subgenus Diaphoranthema members T. virescens, T. recurvata and T. landbeckii as well as Tillandsia purpurea complex members (including T. marconae). “cloned” indicates that the Agt1 sequences were cloned to test for Agt1 copy number and paralog variations. Numbers correspond to accession codes from Heidelberg Botanical Garden (accession details are found with Table S1). Allopolyploid hybrid T. marconae is indicated in blue font. Accessions in red font indicate ambiguous morphological characters and might represent additional accessions of hybrid origin
