We describe a new species from Rio Grande do Norte (Brazil), Hohenbergia densa, that inhabits the dry vegetation of the state. This new species can be recognized by its short and robust habit, differing from other Caatinga-endemic species of the region, that commonly present a broader rosette with a long inflorescence axis. Additionally, we provide...

Bromeliaceae has been used as a model Neotropical group to study evolutionary and diversification processes. Moreover, since large parts of the Neotropics are under anthropogenic pressure, a high percentage of possibly threatened species occurs. Despite this, concrete proposals for conservation based on genetic data are lacking. We compilated all g...
Resumo: A colheita de sementes nativas pode causar variações nos resultados laboratoriais, que em parte se devem às características das espécies, mas também à variação na idade das sementes, produzindo resultados discrepantes nas análises. Em face a esses aspectos, hipotetizamos que o tamanho, a posição dos frutos e sementes no escapo têm efeitos s...
En las selvas y otros ecosistemas las diversas especies que ahí
habitan están en constante interacción. Estas interacciones pueden
variar desde depredación, competencia o incluso, mutualismo
(cuando ambos individuos se ven beneficiados). En el presente
ensayo abordaremos algunas de las muchas relaciones planta-animal que se establecen entre algunos...
Purpose
Members of the plant family Bromeliaceae can uptake nutrients directly from their leaves via leaf absorbing trichomes and their roots have long been reduced to anchorage function,thus overlooked. Recently, evidence has accumulated for a significant role for the roots of some species of tank bromeliads in both water and nutrients absorption....
A new species of Bromeliaceae from the semideciduous submontane forests of Bahia (Brazil) is described and commented: Pseudaraeococcus serranensis R.A. Pontes, E.H. Souza & Versieux. This species is morphologically related to and occurs in sympatry with Pseudaraeococcus lageniformis (R.A.Pontes & Versieux) R.A.Pontes & Versieux, being distinguished...

... & Schult.f. (52 spp.) is a genus of Bromeliaceae endemic mainly to the coastal states of Brazil (Baracho 2004, Cavalcante et al. 2020a, Cavalcante and Silva 2021, except for Hohenbergia andina Betancur, with distribution in Colombia, and H. stellata Schult. & Schult.f. ...
... The genus is widely distributed in Brazil's Northeast region, principally in Bahia state Downs 1979, Benzing 2000, Baracho 2004, Cavalcante et al. 2017, 2018, in which some of its members are endemic to a particular region (Baracho 2004, Cavalcante et al. 2020a, Souza et al. 2021. Many Hohenbergia species are easily found in some phytophysiognomies, such as Hohenbergia catingae Ule in the Caatinga biome, H. vestita L.B.Sm. in rocky fields, and H. blanchetii in Atlantic Forest fragments, and can be found in extensive coastal areas Till 1998, Benzing 2000, Baracho 2004, Cavalcante et al. 2017, 2020a, Cavalcante and Silva 2021. However, knowledge about many species is very scant, and many of them are known only by their holotypes (Baracho 2004). ...

Hohenbergia burle-marxii was compared with H. ridleyi Mez in the taxonomic revision of the genus (Baracho 2004) We used these following papers to complement the description of the species -Hohenbergia burle-marxii (Leme and Till 1996); H. augusta (Baracho 2004); H. capitata (Leme 2010; H. halutheriana (Leme 2012); H. ramageana (Baracho 2004); H. ridleyi (Baracho 2004, Cavalcante andSilva 2021); H. stellata (Baracho 2004 ...
Hohenbergia burle-marxii is one of the rarest species of Hohenbergia (Bromeliaceae), until recently known only by the holotype and its clones. The species had been recorded only once in an imprecise locality in Bahia’s south region. After extensive field work we refound the species and we here present a new geographic range of Hohenbergia burle-marxii, at the same time adding information about its morphology and ecologi- cal traits, including a map and photographs of living plants.
Hohenbergia is one the most diverse genera in Bahia state, and inhabits almost all regions of the state. As a result of ongoing studies on Hohenbergia in Bahia, Brazil, here we describe and illustrate Hohenbergia erecta, endemic to the municipality of Mucugê, at Chapada Diamantina. Hohenbergia erecta differs from its morphologically related, H. catingae, by an elongated tubular rosette (vs short stem with a crateriform rosette), and a once-branched cylindrical inflorescence (vs 2–3-branched pyramidal inflorescence), with branches congested at the apex (vs branches laxly arranged). Due to a small distribution area in the Caatinga forest and based on a spatial analysis we categorized it as Endangered (EN), following the IUCN criteria. Hohenbergia erecta is endemic to the central region of Chapada Diamantina, dominant in the area, where no other known Hohenbergia species have been found sympatrically. It is important, however, that new field expeditions are conducted in the region to observe the richness of the genus at Chapada Diamantina.
Hohenbergia lanata Pereira & Moutinho is an endemic bromeliad of the State of Bahia (Brazil), occurring in an altitudinal transition forest between Caatinga dry woodland and Atlantic Forest. The type material was collected by Roberto Burle-Marx, who introduced it into cultivation in his gardens, but lacking the accurate provenance, only mentioning that it was collected between Milagres and Amargosa municipalities. It was later described by Pereira & Moutinho based on a cultivated specimen. In this work, we present new specimens found in natural populations in an area that coincides with the type locality description, enabling us to expand the description of the species, as well as to provide images of the living plants in the field, adding information about its habitat. The herbarium collections revision and the new population found in the field enabled us to propose an updated conservation status and to better characterize the habit, plant architecture, and to add new morphological comparisons and geographical distribution.
