Abstract The genus Ameroglossum was known only from A. pernambucense, a species found on inselbergs in the states of Paraiba and Pernambuco, Brazil. Ameroglossum manoel-felixii, a new species of Ameroglossum, is described and illustrated here, and morphologically compared with A. pernambucense. Information about the geographic distribution of the new species and karyotypic comparisons of both species using CMA/DAPI banding and nuclear DNA content are also presented. 
An overview of the Brazilian inselberg genus Ameroglossum (Linderniaceae, Lamiales), with the description of seven new species
TLDR
It is hypothesized that the evolution of this genus Ameroglossum is driven by the diversity of their hummingbird pollinators, and seven new species are proposed.
Karyotype differentiation in Ameroglossum (Linderniaceae) and closely related genera endemic to Brazilian inselbergs
TLDR
The karyotypical similarities among the species of Ameroglossum, Catimbaua, Cubitanthus and Isabelcristinia suggest a close relationship between representatives of Linderniaceae typical of inselbergs.
Development of 15 SSR polymorphic markers for the endangered Ameroglossum pernambucense Eb. Fischer, S. Vogel & A. V. Lopes (Scrophulariaceae), and cross-transferability in congeneric taxa
TLDR
The use of 15 polymorphic nuclear microsatellite markers for A. pernambucense in conservation and microevolutionary studies in Ameroglossum are discussed, as well as in the investigation of the importance of pollen-mediated gene flow in keeping genetic diversity in rare species with patchily distributed populations using progeny arrays.
Intra- and interspecific karyotypic variations of the genus Senna Mill. (Fabaceae, Caesalpinioideae)
TLDR
It is indicated that 2n = 28 is the most common ploidy among species of Senna, although other numbers were observed, apparently due to polyploidy or disploidy events; polysomy and aneusomy were also observed.
Chromosomal variability in Brazilian species of Anthurium Schott (Araceae): Heterochromatin, polyploidy, and B chromosomes
TLDR
The heterochromatic fraction in Anthurium was found to be quantitatively variable among species and populations, which may be related with adaptive aspects, different environmental conditions, or phylogenetic position.
Karyotype analysis in Bignonieae (Bignoniaceae): chromosome numbers and heterochromatin.
TLDR
Heterochromatin analyses in Bignonieae revealed only GC-rich regions, with six different arrangements of those bands, although the A-type were the most common and the presence and combinations of the other types appear to be the most promising for taxonomic studies.
Heterochromatin and numeric chromosome evolution in Bignoniaceae, with emphasis on the Neotropical clade Tabebuia alliance
TLDR
The haploid base number of Bignoniaceae is discussed and heterochromatin distributions revealed by CMA/DAPI fluorochromes in the Tabebuia alliance, as well as in some species of the Bignonieae, Tecomeae, and Jacarandeae tribes are examined.
Pollen flow within and among isolated populations of two rare, self-compatible plant species from inselbergs of Northeast Brazil
TLDR
The predominant role of cross-pollination among small, isolated populations as the main force against genetic erosion is suggested, suggesting natural genetic recovery (NGR) in more remote populations.
Paisagem, turismo ecológico, florística e uso da flora rupícola da Serra do Jatobá, Paraíba, Brasil
A Serra do Jatobá constitui um monólito localizado a 10 km do Município de Serra Branca. Destaca-se do relevo suavemente ondulado da região, com uma cobertura vegetal composta principalmente por
The roles of geography and environment in divergence within and between two closely related plant species inhabiting an island‐like habitat
TLDR
This work tested the relative contribution of geographic and environmental isolation in genetic and phenotypic divergence within and between two species of the figwort Ameroglossum inhabiting spatially isolated habitats, known as inselbergs.

Ameroglossum, a new monotypic genus of Scrophulariaceae-Scrophularioideae from Brazil
The new monotypic genus Ameroglossum EB. FISCHER, S. VOGEL & A. LOPES with the new species A. pernambucense EB.FISCHER, S. VOGEL & A. LOPES from Brazil is described. It differs from the related
Checklist of angiosperms from the Pedra Furada Municipal Park, northeastern Brazil
TLDR
The checklist of flowering plants (angiosperms) from the Pedra Furada Municipal Park, in the northeast region of Brazil, provides evidence of the park’s relevance to the preservation of the local flora.
Karyotype differentiation among Spondias species and the putative hybrid Umbu-cajá (Anacardiaceae)
TLDR
From the chromosome banding and the distribution of rDNA sites, as well as from the genomic in situ hybridization, it seems clear that Umbu-caja is related closely to S.monbim and S.tuberosa, but it is karyotypically homozygous and distinct from theses other species.
Karyology of the genus Epidendrum (Orchidaceae: Laeliinae) with emphasis on subgenus Amphiglottium and chromosome number variability in Epidendrum secundum
TLDR
Most lineages of Epidendrum seem to have been secondarily derived from one ancestral stock with x = 20, as is seen in the majority of the present-day representatives of the genus.
Reproductive ecology of Ameroglossum pernambucense (Scrophulariaceae): is this ornithophilous and threatened shrub highly adapted to a naturally fragmented habitat?
TLDR
Study of two populations of A. pernambucense determined if three reproductive features facilitate the colonisation of new areas and the gene flow among the outcrops, and interpreted the reproductive traits observed as highly adapted to its fragmented condition.
Cytological Studies on the Genus Russelia
TLDR
Lack of synchronisation in the meiotic division in the anthers of a flower was found to be characteristic in the two species studied, Russelia equisetiformis and R. coccinea.
Cytogenetics and cytotaxonomy of some Brazilian species of Cymbidioid orchids
TLDR
In the genera Catasetum and Oncidium, the terrestrial and lithophytic species presented higher ploidy levels than the epiphytic species, suggesting a higher adaptability of the polyploids to those habitats.
The evolution of CMA bands in Citrus and related genera
TLDR
The data suggest that the variable number of terminal CMA+ bands observed on chromosomes of Citrus and related genera are probably the consequence of amplification or reduction in the number of CsSat-like sequences distributed on chromosome termini, paralleled by mutation and homogenization events, as proposed by the library hypothesis.
Levantamento das espécies de Scrophulariaceae sensu lato nativas do Brasil
TLDR
The main nomenclatural changes are the inclusion of Otacanthus under Achetaria, Schizosepala under Agalinis and Geochorda under Conobea, with the correspondent new combinations: Achetria azurea (Linden) V.C. Souza and ConobeA glechomoides (Spreng.) V. c.
The relationships among lemons, limes and citron: a chromosomal comparison
TLDR
The hypothesis that C. medica is a true species while the other nine accessions are hybrids is supported, as all of its chromosome types were clearly represented in limes and lemons, some of them forming heteromorphic pairs.
