Understanding the spatial and temporal frameworks of species diversification is fundamental in evolutionary biology. Assessing the geographic origin and dispersal history of highly diverse lineages of rapid diversification can be hindered by the lack of appropriately sampled, resolved, and strongly supported phylogenetic contexts. The use of currently available cost-efficient sequencing strategies allows for the generation of a substantial amount of sequence data for dense taxonomic samplings, which together with well-curated geographic information and biogeographic models allow us to formally test the mode and tempo of dispersal events occurring in quick succession. Here, we assess the spatial and temporal frameworks for the origin and dispersal history of the expanded clade K, a highly diverse Tillandsia subgenus Tillandsia (Bromeliaceae, Poales) lineage hypothesized to have undergone a rapid radiation across the Neotropics. We assembled full plastomes from Hyb-Seq data for a dens...

In September 1981, seeds of Arisaema were harvested by Carla Teune, Hortus Botanicus Leiden, near Liuba, area of Mt Minya Konka (Gonga Shan), Szechuan (Sichuan) Province, China, at 3600 m altitude. During the trip, with Roy Lancaster and others, no pressed herbarium specimen was collected. Michael Hoog, who runned a well known Dutch Nursery, was given five lots of seed numbered CT 368 to CT 372, all provisionally labeled A. consanguineum Schott. All numbers were collected the same day along the same path. After the seedlings flowered, it appeared there was no reason to keep them separate; they were merged and distributed in the trade as Arisaema CT 369 (Antoine Hoog, 1998, private communication). The following Latin description of A. ciliatum H. Li var. liubaense var. nov. corresponds to specimens widespread in culture as Arisaema CT 369. As well known, the name of A. ciliatum H. Li refers to the presence of some cilia along the mouth of the spathe-tube (Fig. 1). The spadix is apica...

Full plastome sequences for land plants have become readily accessible thanks to the development of Next Generation Sequencing (NGS) techniques and powerful bioinformatic tools. Despite this vast amount of genomic data, some lineages remain understudied. Full plastome sequences from the highly diverse (>1,500 spp.) subfamily Tillandsioideae (Bromeliaceae, Poales) have been published for only three (i.e., Guzmania, Tillandsia, and Vriesea) out of 22 currently recognized genera. Here, we focus on core Tillandsioideae, a clade within subfamily Tillandsioideae, and explore the contribution of individual plastid markers and data categories to inform deep divergences of a plastome phylogeny. We generated 37 high quality plastome assemblies and performed a comparative analysis in terms of plastome structure, size, gene content and order, GC content, as well as number and type of repeat motifs. Using the obtained phylogenetic context, we reconstructed the evolution of these plastome attr...

"In 1979 Prof. Werner Rauh described a new Bolivian variety of the Argentinean species Tillandsia jucunda A. Cast. as Tillandsia jucunda var. viridiflora. The main differences are the hanging inflorescences with the green flowers and the more silvery cinereous leaves. Except the green colour of the petals, those characteristics are more typical (see figure ) for the more widespread Tillandsia ixioides Griseb. (Argentina, Bolivia, Paraguay, Uruguay, Brazil), not mentioned in Rauh‘s description of this new variety. A closer study of the flower characteristics proves that this variety is closer to T. ixioides than to T. jucunda. That’s why a new combination along with a new status is proposed: Tillandsia ixioides subsp. viridiflora (Rauh) Gouda, comb. et stat. nov."

For now I think it would be the best to consider Aechmea pseudonudicaulis to be a man made hybrid at the nursery of Alvim Seidel and to remove it from the species list and add it to the BCR as Aechmea ‘Pseudonudicaulis’ (A. nudicaulis x A. comata). Maybe it got mixed up with an other plant or maybe it was a victim of an accidently label exchange that can happen in nurseries and gardens. It is a beautiful middle sized fast growing Aechmea with a very nice colored inflorescence. For the hybrid lovers a plant worth growing. The petals however are not really bright yellow, but seems to have some blue in it (not clearly seen in the pictures), making the color some what dirty yellow, something you also see in some A. comata- like clones we grow.

ABSTRACT Two species of Pitcairnia occurring in the Guianas are proposed to become synonyms (Pitcairnia leprieurii Baker to Pitcairnia rubiginosa Baker and Pitcairnia incarnata Baker to Pitcairnia caricifolia Mart. ex Schult. & Schult.f.). Pitcairnia semijuncta Baker is resurrected as a recognized species and two inselberg species are proposed as new. Descriptions and drawings of the newly described species are provided, as well as an identification key to the 15 Pitcairnia species that occur in or are expected to occur in the Guianas.

Puya colcaensis is described and illustrated as a new species found in the Province of Caylloma (Arequipa) in southern Peru. This species has a compound inflorescence, bluish-green flowers, with pedicels smaller than 1.5 cm, which are exceeded by the floral bracts, and sepals with dense stellate trichomes. It is similar to P. araneosa and P. adscendens.

Racinaea penduliflora Gouda & Manzan., sp.nov.
By coincidence both authors were initially working independently on manuscripts describing material that, we later found out, related to the same new species. Manzanares had the specimen collected by Robin B. Foster on loan from the Missouri Botanical Garden (MO) and Gouda was working on the C. Porter et al. specimen after Ricardo Fernández contacted Gouda by email for a name for their 3 collections from Cuzco. The much smaller Foster specimen has been chosen for the holotype because it was collected at anthesis. This specimen seems to be slightly more bulbose than the
comparatively utriculate Porter et al. collections. The taller plants of the Porter et all. collections are from the Dept. of Cuzco and are collected not more than 50 km apart of each other, but the Foster collection is 500 km to the North-East in the Dept. of Pasco. All collections are from the damp montane forest at the Amazonian side of the main ridge of the Andes, Peru.

Summary. The ferms used by Mez (1896, 1934), and Smith & Downs (1974, 1977, 1979), sneb as "bi-/tripinnate", "scape" and "inflorescence" for example, in ways that deviate front those proposed by Linnaens, and other ferms nsed in a non-Linnean tradition in Bromeliaceae Literatiire (anterior, posterior, actinomorph, zygomorph, irregular, imbricate) are presented together with their use in general botany. Furfhermore, a catalogne of all parts of a bromeliad plant (Gouda 2007) is published as a guide line to describe, for exanple, specimens of a new taxon. Definitions of differently understood organs (inflorescence, scape, bi-/ tri-pinnate) are given.

Some specimens are travelling from one Botanic Garden to another without a proper name and that was how we got a plant named “Billbergia sp. Brazil, Seidel 1047”. How it came to Europe is not clear to me, but we got it from B.G. Vienna (Austria) who in turn got it from B.G. Halle (Germany). I missed the first time it flowered in 2009/2010, but in January this year it was flowering again and it was obviously not a Billbergia, but seems to be intermediate between Aechmea nudicaulis (L.) Grisebach (1864:593) and A. comata (Gaudich.) Baker
(1879:234). Walter Till suggested I check the publication of A.pseudonudicaulis Leme (1987:394, fig.p.401) that was described in Bradea 4(50): 394. The holotype was said
to be collected in Espirito Santo, Baixo Guandu, by Alvim Seidel 1074. Flowered in cultivation on 20 Aug. 1987 (Holotype HB n.s.).

Pitcairnia marinii Manzan. & W Till in Manzanares (2005: 437-8) is a very nice and easy medium sized species. Before flowering the plant is about 50 cm tall and forms several shoots from the base, which makes it easy to split a plant for vegetative propagation. It has nice distinctly nerved foliage and is wholly spineless.

In 1979 Prof. Werner Rauh described a new Bolivian variety of the Argentinean species Tillandsia jucunda A. Cast. as Tillandsia
jucunda var. viridiflora. The main differences are the hanging inflorescences with the green flowers and the more silvery cinereous leaves.
Except the green colour of the petals, those characteristics are more typical (see figure ) for the more widespread Tillandsia ixioides Griseb. (Argentina, Bolivia, Paraguay, Uruguay, Brazil), not mentioned in Rauh‘s description of this new variety.

Four new species belonging to the genus Racinaea (formerly Tillandsia subgenus Pseudo-Catopsis, Bromeliaceae) from Ecuador are described and illustrated here. The new species R. condorensis from the province of Zamora-Chinchipe in the southern region of Ecuador is similar to R. contorta. Racinaea guacamayosensis from the Cordillera de los Guacamayos, an area close to Tena in the province of Napo, has close affinity with R. diffusa and R. penlandii. Racinaea terrestris from the province of Morona-Santiago, southern Ecuador, is also similar to R. diffusa. The new species R. tillii from the cloudy, cool mountain forest on the Amazonian side of the Andes in Napo province, is very alike R. penlandii. Distinguishing characters between these species are provided.
