The authors provide a new circumscription for genera of the “Cryptanthoid complex” Bromeliaceae subfam. Bromelioideae, originally composed Cryptanthus, Lapanthus, Orthophytum, and Sincoraea, on basis or re-evaluated ecological, geographical morphological evidence, as well molecular phylogenies. A generic status is proposed Cryptanthus subg. Hoplocryptanthus two genera, Forzzaea, Rokautskyia, four subgenera in Orthophytum (Capixabanthus, Clavanthus, Krenakanthus, Orthocryptanthus) are described to render taxonomic units monophyletic. recognized taxa circumscribed by combination range, ecology characters (sex distribution, leaf succulence, sepal petal size connation, appendages, pollen stigma morphology, fruit size, calyx persistency, seed number per fruit). Field collected living specimens 78 81 species s.l., all 58 59 Sincoraea were analysed habitat and/or cultivation, allowing documentation illustration underutilized characters. analysis incorporated 91 accessions representing 33 (3) 42 9 including type first three outgroup taxa. results suggest, that some generally considered homoplasious complex”, not at least within obtained, biogeographycally delimited clades their taxonomical utility redeemed.
