| Xylem anatomical traits can provide insights regarding the mechanisms affecting the distribution of vascular plants across environmental gradients. In this study, we aimed to investigate the hypothesis that lianas occurring in semiarid environments have characteristics that maximize the xylem resistance to tension-induced cavitation along the root-stem-branch continuum. To gather information regarding the hydraulic architecture of the lianas, we analyzed several anatomical traits of wood: cross-sectional area occupied by the parenchyma (AP), fibers (AF), and vessels (AV); average vessel diameter (d); wood density (WD); pit diameter in the vessel wall (dpit); pit density (Npit), and potential hydraulic conductivity (Kp) in branches, stems, and roots of... |

| Systematic studies of angiosperm fossil woods from sediments of the Río Leona Formation were continued. A new morphospecies of Maloidoxylon with affinity to Rosaceae was described and constitutes, together with the fossil pollen from the same strata, the oldest South American fossil with this familial affinity. Nothofagaceae fossil woods are represented by the morphospecies Nothofagoxylon scalariforme Gothan, Nothofagoxylon kraeuseli Boureau et Salard, Nothofagoxylon triseriatum Torres et Lemoigne, Nothofagoxylon ruei Salard and a new morphospecies of Nothofagoxylon. Three of the four subgenera of Nothofagus were recognized in the fossil woods and a new infrageneric affinity for Nothofagoxylon ruei was proposed. The described woods have affinity to extant... |

| This paper aimed to characterize the anatomical structure of the wood of specimens of Mollinedia glabra (Spreng.) Perkins growing in two contiguous formations of restinga vegetation at Praia Virgem, in the municipality of Rio das Ostras, RJ. Both the Open Palmae (OPS) and the Sandy Strip Closed Shrub (SSCS) formations are found in coastal regions that receive between 1,100 and 1,300 mm of rainfall per year. Sapwood samples were collected in both formations. Typical anatomical features for this species include: solitary vessels, radial multiples or clusters elements, that are circular to angular in outline, 5-15 barred scalarifor perforation plates, ood parenchya scanty, septate fiber-tracheids, and wide multiseriate rays with prismatic crystals.... |

| ABSTRACT Anthracological studies are firmly advancing in the tropics during the last decades. The theoretical and methodological bases of the discipline are well established. Yet, there is a strong demand for comparative reference material, seeking for an improvement in the precision of taxonomic determination, both in palaeoecological and palaeoethnobotanical studies and to help preventing illegal charcoal production. This work presents descriptions of charcoal anatomy of eleven Anacardiaceae species from six genera native to Brazil (Anacardium occidentale, Anacardium parvifolium, Astronium graveolens, Astronium lecointei, Lithrea molleoides, Schinus terebenthifolius, Spondias mombin, Spondias purpurea, Spondias tuberosa, Tapirira guianensis, and Tapirira... |

| La investigación se llevó a cabo en el municipio de Cazones de Herrera, Veracruz, México, en una huerta comercial de naranjo ‘Valencia’ injertado en cuatro portainjertos: limón ‘Volkameriano’ (C. volkameriana Ten. & Pasq.) y los mandarinos ‘Cleopatra’ (C. reshni Hort. ex Tan.), ‘Amblicarpa’ (C. Amblicarpa (Hassk.) Ochse) y ‘Común’ (C. reticulata), tolerantes al Virus de la Tristeza de los Cítricos (VTC). Durante dos ciclos de producción (2005-2007), se evaluó crecimiento del árbol, producción, calidad de la fruta y anatomía de la madera. Se utilizó un diseño experimental completamente al azar, con cuatro tratamientos, diez repeticiones y dos árboles por unidad experimental. Los resultados indican que, el naranjo ‘Valencia’ es afectado por el... |

| Plants of six species from the Melastomataceae family (Miconia spp. and Bellucia spp.) taken from secondary forest stands of Terra Firme near Manaus, Amazonas, Brazil, were studied with regard to growth form, biometric traits of the plants, morphological and anatomical characteristics of leaves and wood. In addition, plant biomass and the content of mineral nutrients of different parts of the plants were analysed, and xylem flux measurements were carried out to determine the specific water uptake of the plants. The aim of the studies was to detect causal links between the parameters measured and the ecological behaviour of the species as observed in the field, in order to provide an autecological description of the species. The results show that the plant... |

| Systematic wood anatomy of the tribe Guettardeae (Rubiaceae). The wood anatomy of nearly all genera of the Guettardeae (Rubiaceae, Guettardoideae) has been examined, and in this respect the tribe is heterogeneous. Suggestions are made for a delimitation of the tribe. Guettarda, Bobea, Antirhea, Malanea and Chomelia Jacq. are sufficiently similar in their wood anatomical characters to warrant retention in the same tribe. Machaonia, Timonius and Dichilanthe are anomalous. Suggestions are given for taxonomic revisions of some genera based on their wood anatomy. |
