“…In our field work we also registered the occurrence of T. paraibensis at Pedra do Cruzeiro, RN. Populations were found on vertical rocks (Figure 2E), in the same habitat as observed by Pontes (2012), and growing close to Orthophytum disjunctum mats. Although all individuals were sterile, the vegetative characters fit perfectly within the protologue of this recently described taxon and the proximity to the type locality is another evidence about its identity.…”

“…This enormous geographical distribution is a consequence of the great seed dispersal capacity provided by light plumose appendages and several ecophysiological adaptations (Benzing 2000). Tillandsia paraibensis R.A. Pontes is a recently described species that was known to occur only in three inselbergs in the north of Paraíba state: Pedra da Boca, Pedra da Santa and Pedra do Carneiro (Pontes 2012). In our field work we also registered the occurrence of T. paraibensis at Pedra do Cruzeiro, RN.…”

The largest portion of the northeastern Brazil is covered by the caatinga vegetation (Albuquerque et al. 2012). This tropical dry forest covers eight states and areas with semiarid climate characterized as a result of low rates of precipitation, which is concentrated over a short annual period (Leal et al. 2003). The caatinga is the only phytogeographic domain that is confined to the Brazilian territory. It harbours great biodiversity, with many still understudied. The lack of scientific research marks the history of caatinga areas; nevertheless, this scenario has been changing in the past few decades with an increase in the number of related studies (Albuquerque et al. 2012).The flora of Rio Grande do Norte (RN) is not well represented in its two major local herbaria collections (MOSS and UFRN) due to laxity of complete and representative samples. Together they barely exceed 20,000 specimens (Thiers [continuously updated]). Within this state the lack of investment in long and intensive research programs focused on biodiversity inventories Abstract: In the present work we describe the first occurrence of the genus Orthophytum (Bromeliaceae, Bromelioideae) and of the species Tillandsia paraibensis within the state of Rio Grande do Norte, northeastern Brazil. Both taxa were recorded on inselbergs in areas of caatinga. These findings are important, improving the knowledge of the Flora of Rio Grande do Norte and giving a better understand of the biogeography of Brazilian bromeliads.

“…In addition to these two new genera, many new populations of Ameroglossum have been discovered, which exhibit a greater morphological diversity than previously known. A number of populations represent undescribed species, which follows the trend of recent taxonomic discoveries from the inselbergs in north-eastern Brazil (e.g., Pontes 2012;Cordeiro et al 2018;Cardoso et al 2019aCardoso et al , 2019bde Lima et al 2019;Santos et al 2019;Morales & Morais 2020;Morales & Kollmann 2020), showing that this often taxonomically neglected region of Brazil has a greater diversity than previously assumed.…”

Field studies of the inselberg flora of north-eastern Brazil have resulted in the discovery of much greater morphological diversity of the genus Ameroglossum, than previously envisaged. These enigmatic plants are endemic to isolated rock outcrops, which have long been surrounded by unsuitable habitat. The morphological forms are geographically isolated and stable in cultivation when grown under similar conditions. We here provide detailed descriptions of the two previously known species and propose an additional seven new species in the genus. A taxonomic revision of the genus, including an identification key is provided. We hypothesize that the evolution of this genus is driven by the diversity of their hummingbird pollinators. Due to the threatened nature of inselberg habitats and the small populations found for most taxa, the species described here are likely to be under threat and in need for formal redlisting.

Disentangling theTillandsia capillariscomplex: phylogenetic relationships and taxon boundaries in Andean populations

et al. 2016

We studied the genetic diversity and structure of the Tillandsia capillaris complex, a morphologically diverse group of highly specialized epiphytes, across the distribution range in arid mountain regions of central Peru, Chile, Bolivia and central Argentina. To elucidate the phylogenetic relationships in the complex and to explore the taxon boundaries among populations, we used three plastid markers (rpoB-trnC-petN, trnK-matK-trnK, ycf1, c. 8100 bp in total) and one single-copy nuclear gene (PHYC, c. 1200 bp) for 69 populations and 96 individuals of the T. capillaris complex plus 16 outgroup taxa. Bayesian inference of plastid DNA data indicates the existence of two evolutionary core lineages, which can be recognized as two distinct species: T. capillaris and T. virescens (as proposed previously on the basis of morphological characters). Tillandsia capillaris is a monophyletic and homogeneous group, widely distributed and less genetically variable, whereas T. virescens (including T. kuehhasii) is genetically more divergent with most of the forms growing at high elevation in arid areas, except for the small clade including T. virescens s.s. (= T. cordobensis), which grows in lower, more humid habitats. The nuclear analysis resulted in a polytomy with some individuals showing incongruent positions between plastid and nuclear topologies. The high haplotype diversity, consisting of 63 plastid DNA haplotypes in 69 populations, was resolved as two core lineages occurring from north to south, allowing us to establish a preliminary view of the genetic variation overlapping between the two taxa. The results suggest that the genetic differentiation into two main clades is consistent with morphological variation in this Andean complex.
