Abstract:—A taxonomic revision of Bromeliaceae subfam. Tillandsioideae is presented based on a multi-locus DNA sequence phylogeny (viz., plastid DNA loci rpoB-trnC-petN, trnK-matK-trnK, and ycf1, and the nuclear DNA gene PHYC) and new or re-evaluated morphology (e.g., leaf, inflorescence, sepal, petal, ovary, stigma, stamen, pollen, ovule, and seed morphology). This enables the circumscription of monophyletic units using synapomorphic combinations of diagnostic morphological characters. Stigma morphology has proven to be indicative for super-specific taxa in Tillandsioideae. One new stigma type and several subtypes of previously described stigmas were found. The four tribes proposed earlier are mostly confirmed, but Catopsideae replaces the formerly used name Pogospermeae for the monotypic tribe of Catopsis. In addition, the two new subtribes Cipuropsidinae and Vrieseinae are proposed within tribe Vrieseeae. Several new genera are established to render taxonomic units monophyletic and morphologically well circumscribed. They represent segregates of either Mezobromelia (Gregbrownia: 4 spp.), Tillandsia (viz., Barfussia: 3 spp., Josemania: 5 spp., Lemeltonia: 7 spp., Pseudalcantarea: 3 spp., and Wallisia: 4 spp. and 1 hybrid), or Vriesea (viz., Goudaea: 2 spp., Jagrantia: 1 sp., Lutheria: 4 spp., Stigmatodon: 18 spp., and Zizkaea: 1 spp.). The new subgenera Tillandsia subg. Pseudovriesea and T. subg. Viridantha are established, and T. subg. Aerobia is resurrected. An identification key to all accepted genera of Bromeliaceae subfam. Tillandsioideae is provided. Furthermore, to clarify nomenclatural uncertainties, typifications are proposed for Catopsis subg. Tridynandra, Thecophyllum [unranked] Biflorae, Tillandsia subg. Aerobia, T. sect. Caricifoliae, T. sect. Conostachys, T. sect. Cyathophora, T. sect. Eriophyllum, T. sect. Macrocyathus, T. sect. Platystachys Baker auct. non al., Tillandsia sect. Strepsia, Vriesea subg. Conostachys Mez auct. non al., T. lindenii K. Koch auct. non al., and T. macropetala.

Taxonomy:—Aerobia (subgen. of Tillandsia) Type designated: Tillandsia xiphioides Ker Gawl. (p.45).—Allardtia (subgen. of Tillandsia) Several species of former T. subg. Allardtia (including its type T. guatemalensis) are also included here. Tillandsia subg. Allardtia is therefore a synonym of T. subg. Tillandsia. (p.47).—Barfussia wagneriana Moore (1993) corrected the type locality for the holotype of Tillandsia wagneriana, Moore 310 (holo US), vicinity of Moyobamba, Depto. San Martín, Peru. (p.40).—Cipuropsis Resurrected from Vriesea (p.50).—Conostachys (section of Tillandsia) Type(designated here):Tillandsia mucronata Griseb. [≡ Guzmania mucronata (Griseb.) Mez] (p.40).—Conostachys (section of Vriesea) Type (designated here):—Vriesea malzinei E. Morren (p.46).—Cyathophora (section of Tillandsia) Type (designated here):—Tillandsia utriculata L. (p.46).—Eriophyllum (section of Tillandsia) Type(designated here):—Tillandsia setacea Sw. (p.46).—Jutleya (section of Werauhia) Not recognized subgenus (p.54).—Platystachys (subgen. of Tillandsia) Type (designated here):—Tillandsia setacea Sw. (p.46).—Strepsia Steudel (1841: 645) did not validly publish Strepsia as a name at a new rank based on Tillandsia sect. Strepsia, because he did not accept the genus. This is evident by Steudel writing ‘Strepsia. Nuttal.’ and not ‘STREPSIA’, the capital letters indicating genera accepted by him in the whole publication. Furthermore, he referred the only species listed, ‘Strepsia usneoides. Nutt.’, as synonym to Tillandsia usneoides (L.) L., the italicized letters of species epithets indicating species not accepted by him in the whole publication. Under the accepted genus ‘TILLANDSIA’, ‘Strepsia usneoides. Nutt.’ is also cited as synonym of Tillandsia usneoides(Steudel 1841: 688). Currently there is no evidence that Strepsia was already earlier validely pubished as a genus. (p.45-46).—Strepsia (section of Tillandsia) Type (designated here):—Renealmia usneoides L. [≡ Dendropogon usneoides (L.) Raf., Tillandsia usneoides (L.) L.]. Note:—30 species. (p.45).—Tillandsia guatemalensis Allardtia cyanea A. Dietr. (1852) is a valid and legitimate. The name Tillandsia cyanea in Koch’s article (1867) was not validely published by Koch, as he did not accept the name for the exhibited plant in Paris (which was a Bromelioideae according to the text). This means, the name Tillandsia cyanea was still available at that time. The combination of Allardtia cyanea A. Dietr. under Tillandsia by Morren as Tillandsia cyanea (A.Dietr) E.Morren (1879) for this taxon is therefor valid and legitimate, because Tillandsia cyanea was still available. The new name Tillandsia guatemalensis L.B. Sm. (1949) for Allardtia cyanea is illegitimate and superfluous, as the correct name is Tillandsia cyanea (A.Dietr) E.Morren (p.48).—Tillandsia heliconioides Belongs to subgenus Tillandsia following DNA research .—Tillandsia lindenii Neotype (designated here): Plate 18 in Belgique Hort. 19 (Nov–Dec 1869) (p.47).—Tillandsia malzinei Belongs to subgenus Tillandsia following DNA research .—Tillandsia platyrhachis var. magnifica Considered conspecific with the type variety (p.39).—Tridynandra Type (designated here):—Catopsis morreniana Mez (p.37).—Vriesea ochracea Vriesea ochracea Rauh & E.Gross [≡ Werauhia ochracea (Rauh & E. Gross) J.R. Grant] is excluded from Werauhia and transferred back into Vriesea s.str. (p.55).—Wallisia cyanea Nom. nov. pro Tillandsia lindenii K. Koch (23 May 1868).
