| We report morphodiagnosis, and phytochemical and antimicrobial investigations of Tabebuia aurea. It was noted that the leaves are compostas with anomocytic stomata only on the lower side; the vascular system is concentric andthe mesophyll arrangement is dorsiventral. From the stem bark eight compounds were isolated, including: lapachol, 3,4',5-trihydroxy-7-methoxyflavone, b-sitosterol, betulinic acid, p-anisic acid, veratric acid, methyl cinnamate and ethyl p-hydroxy-cinnamate. Antimicrobial assays showed growth inhibition the of Gram positive and Gram negative bacteria, alcohol-acid bacterium and fungi. |

| Jacaranda decurrens (Bignoniaceae) is an endemic species of the Cerrado with validated antitumoral activity. The genetic diversity of six populations of J. decurrens located in the State of São Paulo was determined in this study by using molecular markers for randomly amplified polymorphic DNA (RAPD) and amplified fragment length polymorphism (AFLP). Following optimization of the amplification reaction, 10 selected primers generated 78 reproducible RAPD fragments that were mostly (69.2%) polymorphic. Two hundred and five reproducible AFLP fragments were generated by using four selected primer combinations; 46.3% of these fragments were polymorphic, indicating a considerable level of genetic diversity. Analysis of molecular variance (AMOVA) using these two... |

| Zeyheria montana, an endemic species of the Bignoniaceae family from the Brazilian Cerrado's known for its anti-cancer properties, is widely used as imuno stimulant in the popular medicine and its therapeutic activity must be validated by scientific data. The objective of this work was to evaluate the genetic variability of eight plant populations collected within the state of São Paulo, Brazil, via Random Amplification of Polymorphic DNA (RAPD) used as molecular markers. After an optimized protocol for the amplification reaction, nine selected primers generated 105 reproducible bands, indicating up to 60% polymorphism. Analysis of molecular variance (AMOVA) revealed higher genetic variation within populations (84.03%) than among populations (15.97%). The... |

| The ovule of Tabebuia pulcherrima is anatropous, unitegmic and tenuinucellate. The nucellus shows a trizonate structural organization. The integument is initiated by periclinal divisions in the dermal layer (zone I), around the base of the archesporium. Subsequently, cells derived from the subdermal layer (zone II) start to push the dermal cells, so that they shift toward the micropylar region. The archesporial cell differentiates directly into the megaspore mother cell, undergoes meiosis, and originates a linear tetrad of megaspores. The mature embryo sac mother cell is elongated, possess a conspicuous central nucleus, and a characteristic bipolar vacuome with fibrous-granulated content. The inner cell layers of the integument differentiate into an... |

| Anemopaegma arvense (Vell) Stellf. ex de Souza belongs to the family Bignoniaceae, and is popularly known as catuaba. To evaluate the cytotoxic and antimicrobial activity of A. arvense, fraction F3 and flavonoids 1 (quercetin 3-O-α-L-rhamnopyranosyl-(1→6)-β-D-glucopyranoside) (rutin) and flavonoid 2 (quercetin 3-O-α-L-rhamnopyranosyl-(1→6)-β-D-galactopyranoside) were isolated from the leaves of this plant. Fraction F3 and flavonoids 1 and 2 exhibited no antibacterial activity. Furthermore, no cytotoxic activity of fraction 3 or flavonoids 1 and 2 was observed against the tumor cells tested. However, analysis of the antifungal activity of flavonoids 1 and 2 revealed minimum inhibitory concentrations of 0.5 and 0.25 mg/mL, respectively, against the... |

| This study reports the mite fauna associated with Tabebuia roseo-alba, a native and ornamental tree, determining the abundance and seasonal occurrence of species and the diversity of the community. Twenty three species were found belonging to 11 families, 10 of predatory habits and five phytophagous. The food habits of the eight remaining species are not known. Besides the great richness, the diversity was small, as consequence of the dominance of Lorryia formosa Cooreman, 1958 and Aculus sp., the most abundant species. These species occurred in the same microhabitat but with seasonal segregation: L. formosa was the most abundant in the dry season, while Aculus sp. occurred only in the rainy season. In August, when the plant lost its leaves, the following... |

| The immature stages of Adelpha malea goyama Schaus are described from the Estação Ecológica do Caiuá, Paraná State, Brazil. The species uses the native liana Arrabidaea mutabilis Bur. & K. Schum. (Bignoniaceae) as larval hostplant in the study site. Isolated eggs are laid on leaf tips, and are similar in shape to those described for other species of Adelpha Hübner. Larvae pass through five stadia during 21 days, and first to third instars construct frass chains. Later instars rest on the upper leaf surface, and their body is covered by rigid branched scoli. The general profile of the pupa is elongated, with short head horns projecting laterally and with segment A2 projecting and curved anteriorly. Comparisons with closely related species of Adelpha... |

| El objetivo del presente trabajo es estudiar la forma de crecimiento de Dolichandra cynanchoides, especie trepadora característica del bosque serrano de la Provincia de Córdoba (Argentina), e inferir sus caracteres adaptativos. Los estudios se realizaron en su ambiente durante tres años consecutivos y en invernáculo los dos primeros años de vida. La forma de crecimiento de esta especie resulta de la presencia y combinación de los siguientes caracteres: liana perenne, germinación criptohipógea, vástagos aéreos predominantemente ortótropos y subterráneos ligeramente plagiótropos, sinflorescencias constituídas por tirsas con florescencias parciales dicasiales, raíz principal y raíces adventicias. El tallo presenta una estructura anómala, la cual le otorga... |
