“…Species of the Bignoniaceae have been reported to present an uniseriate epidermis (Metcalfe and Chalk ), an observation that was corroborated in the present study. However, the presence of one or more layers of hypodermis was previously reported in Pandorea (Metcalfe and Chalk ) and Handroanthus (Silva et al ). In this study, two layers of epidermal cells were encountered on the adaxial surface of the leaflet blade of A. glaucum var.…”

“…Perhaps the best known anatomical study of the Bignoniaceae is that of Armstrong (), who used floral anatomical characters to define the taxonomic position of Paulownia, Schlegelia, Gibsoniothamnus and Synapsis . In addition, Lersten et al () conducted a morpho‐anatomical study on the wall thickenig of xylem‐conducting elements present in the wings of the seeds, while Silva et al (), characterized the leaf anatomy of six species of Handroanthus and one species of Tabebuia . More recently, Pace et al (, ) studied wood anatomical traits in representatives of the tribe Bignonieae, with an emphasis on traits associated with the regular and variant phloem.…”

Anemopaegma is a monophyletic lineage included in the tribe Bignonieae. The genus is taxonomically problematic, especially in the Anemopaegma arvense species complex, a group whose taxa have been delimited on the basis of leaf external morphology. Here we study the leaf anatomy of all three species and nine varieties currently included in this species complex (A. acutifolium DC., A. arvense (Vell.) Stellf. ex de Souza and A. glaucum Mart. ex DC.) in search for additional characters that may help circumscribe taxa within this group. For comparison, this study also investigated the leaf anatomy of two species that are morphologically similar to representatives of the species complex but currently placed outside it (A. album Mart. ex DC. and A. scabriusculum Mart. ex DC.). All taxa were analyzed using standard anatomical procedures and light microscopy. In addition, leaves of A. acutifolium and Anemopaegma album were analyzed with scanning electron microscopy (SEM). Overall, stomata position, composition of the vascular system of the petiole, midrib, lateral veins and margin constitution represented the most important anatomical features for the recognition of the species and varieties. The study also demonstrated that A. scabriusculum presents leaf anatomical traits that differ from those encountered in species of the Anemopaegma arvense complex, corroborating earlier anatomical and molecular phylogenetic results and indicating that A. scabriusculum is indeed best placed outside the A. arvense species complex. Leaf anatomical data also support the synonymization of some varieties of A. mirandum with A. arvense, as well as varieties of A. glaucum into this species.

“…T. aurea leaves present an epidermis and degree of lignification that confer greater resistance to decomposition and/or damage by herbivores. The epidermis of the T. aurea leaves is cuticularised (uni-and biserial) (Silva et al, 2009) and has a broad anatomical plasticity that allows a high capacity for water regulation (Dousseau et al, 2008), which are important features in species that inhabit semiarid regions. A. pyrifolium invests in other leaf traits as a strategy to support water scarcity and predator attack: leaves are more tender and softer (Tab.…”

Leaf traits of Brazilian semiarid species as regulatory factors for associated aquatic invertebrates

The input of leaf litter is an important energy source for the riparian vegetation of aquatic ecosystems, and the chemical composition of leaf litter is decisive for colonization by invertebrates in streams. Plant species of the semiarid regions present different morphophysiological characteristics to combat the effects of drought, including tough leaves that have less nutritional quality. However, although concern regarding the decomposition of organic matter in aquatic ecosystems in semiarid regions is increasing, no information exists on the influence of leaf traits (e.g., N, C:N ratio and toughness) before the colonization of invertebrates and the decomposition of leaf litter. We hypothesized that: i) leaves with greater toughness, higher C:N ratio and lower amount of N present low density and biomass of associated invertebrates; ii) greater density and biomass of associated invertebrates results in increased decomposition rates; and iii) leaf traits influences the structure and composition of functional feeding groups of associated invertebrates. We incubated senescent leaves of Tabebuia aurea and Aspidosperma pyrifolium in a Brazilian semiarid stream using litter bags, and after 3, 7, 15 and 30 days, four litter bags were withdrawn for laboratory washing of the remaining leaf sediment and for collection of associated invertebrates. A. pyrifolium leaves presented higher nutritional quality (low C:N ratio, lower toughness), and the decomposition rate was higher than T. aurea leaves. Invertebrate density and biomass varied among litter, being higher in T. aurea and A. pyrifolium, respectively. The leaf litter quality also altered the composition of functional feeding groups. We observed a higher density of filters on T. aurea and collectors on A. pyrifolium. Both T. aurea and A. pyrifolium presented higher biomass of collectors, however T. aurea showed higher biomass of filters than A. pyrifolium. In the absence of shredders, leaf litter may have been used by invertebrates as a substrate, for shelter against predators and current, and sporadically as a food resource. Thus, differences in the leaf traits were important structures of the streams invertebrate. These are the first results of the influence of leaf traits on invertebrate colonization in the streams of semiarid regions, and reinforce the need for studies to verify the contribution of organic matter as well as the feeding preferences of invertebrates.

“…Tabebuiaspecies occurin neotropical regions, especially from the USA to Argentina and Chile (Santos, 2017). The genus can also be found in tropical and subtropical areas, and includes many temperate climate species, such as ipês (Son et al, 2006;Silva et al, 2009;Gómez-Estrada et al, 2012;Jiménez-González et al, 2013;Silva et al, 2016).…”

“…Representatives of the genus can also be found in Brazil. These vary a great deal, and together with the species of the Handroanthus genus, are known as the Brazilian Ipê (Severiano, 2016).They are generally large hardwood trees, and feature distinctive colored flowers, which can be white, yellow or purple (Silva et al, 2009;Martins, Lago & Cicero, 2011). Species of the Tabebuia genus are popullarly known as ipê, and their wood is resistant to termites.…”

The Tabebuia genus is one of the largest genera of the Bignoniaceae family, comprising more than 100 species. One of its main representatives is the ipê tree, which is popularly known for their ornamental and logging potential. However, parts of the tree, such as the stem, leaves and flowers, are used in traditional medicine for anti-bacterial, anti-inflammatory (rhinitis, sinusitis, tonsillitis and pharyngitis), anti-ulcerogenic, antiviral, antineoplastic, antimalarial and immunomodulatory purposes. The objective of the present study was to collate articles on the cicatrizing and therapeutic properties of species belonging to the Tabebuia spp genus.
