Styrax camporum Pohl is a shrub common in the cerrado vegetation of south-eastern Brazil. Root and stem wood in Styrax camporum differ quantitatively and qualitatively. Quantitative differences follow normal expectations: roots have wider and longer vessel elements, a lower vessel frequency, a lower ray frequency, and wider rays. Qualitative features of the roots are: simple perforation plates, vestured pits, and septate libriform fibres; qualitative features of the stems are: multiple perforation plates, non-vestured pits, and non-septate fibre-tracheids. Based on generally accepted evolutionary trends, root wood of Styrax camporum has more specialized features than stem wood. Additional comparative studies of stem and root anatomy are needed to determine if such differences between root and stem anatomy are widespread, and consistent with the lines of specialization observed in monocotyledons.

The wood anatomy of Huberia consimilis, Miconia amoena, M. mirabilis, M. rimalis and Tibouchina francavillana (Melastomataceae) is described and compared with other species from the same genera. All taxa share vestured pits, absent or inconspicuous growth rings, septate fibres, parenchyma-like tangential bands, and fibres shorter than 900 μm which is characteristic of the family Melastomataceae. Each species exhibited a set of wood anatomical characteristics that enabled its identification. Some traits were more relevant in distinguishing genera, such as composition of parenchyma-like tangential bands, vessel-ray pits, ray width, rays per millimetre and fibre length. Parenchyma-like tangential bands are described in great detail, and we propose a more specific nomenclature for their anatomical classification.

The wood anatomy of four Atraphaxis taxa that have natural distribution in Turkey—Atraphaxis billardieri Jaub. & Spach, Atraphaxis billardieri subsp. tournefortii (Jaup. & Spach) Lovelius, Atraphaxis spinosa L., and endemic Atraphaxis grandiflora (Willd.)—were compared in this study. The wood samples were sectioned according to standard techniques. Samples were macerated with Schultze’s method. Tangential and radial vessel diameters, intervessel pit diameters, vessel wall thickness, vessel elements length, dimensions of libriform fibres (lengths, widths, cell wall thickness and, lumen diameter), and uniseriate and biseriate ray heights were measured, and the number of vessels per mm2, number of rays per mm, and number of vessels per group were counted. The qualitative features such as growth rings, vessel grouping, presence of helical thickening and storied structure, vestured pits, type of perforation plate, and arrangement of axial parenchyma were determined. These four species of Atraphaxis shrubs differ in some wood characteristics such as growth rings, vessel grouping, vestured pits, height and density of rays, number of vessels per mm2, and the dimensions of the vessel.

The wood anatomy of 162 species from China, belonging to 30 genera of the Rosaceae is described. The structural diversity is documented in a survey of characters, a family description, generic descriptions and tables. A key to the genera or groups of genera is presented. A number of genera is described wood anatomically for the first time. Vestured pits noted in some Spiraea species are newly recorded for the farnily . The phenomenon of fibre dimorphism in Spiraea is analysed in detail.

This paper describes the wood anatomy of Mimosa uruguensis Hook et Arn. (Leguminosae Mimosoideae). Photomicrographs and quantitative data of its anatomical structure are also furnished.The anatomical structure is specialized and typical to the Leguminosae. Vestured pits in vessel members, rays composed by only procumbent cells and pores in clusters, tending to a dendritic pattern, are the most important features of this wood.The anatomical structure is compared with literature on the Leguminosae family and Mimosa L. genus, in a taxonomical and phylogenetical analysis.

The wood anatomy of Albizia austrobrasilica Burk. is described and photomicrographs of its structure are furnished.Very short vascular elements, simple perforation plates, paratracheal axial parenchyma, homogeneous rays and libriform fibres, are the most important features in the wood anatomy. These aspects are common among the Leguminosae and indicate a high level of wood specialization. Septated fibres, vestured pits and the absence of any kind of storied arrangement of cells (ripple marks), are also important to the identification of this wood.

The wood anatomy of 31 species representing four genera of subtribe Myrciinae, Myrtaceae, Calyptranthes, Gomidesia, Marlierea and Myrcia is described. In general the wood of subtribe Myrciinae can be characterised by solitary vessels, simple perforations, alternate vestured pits, fibres with bordered and/or vestured pits (fibre-tracheids), parenchyma scanty paratracheal, diffuse and/or diffuse-in-aggregates forming complete or interrupted bands, and heterocellular rays with disjunctive cell walls. The four genera share all these features, but exhibit considerable variation in axial parenchyma patterns and crystal occurrence and distribution. No anatomical features serve to separate the genera, but some, e.g., helical thickenings and crystals, appear to be restricted to species in one genus or another.

The wood anatomy of Didymopanax morototonii (Aubl.) Dcne. & Planch. and Pentapanax warmingianus (March.) Harms. are studied in their general and microscopic features. Both species share the most important anatomical features, described in the literature for the Araliaceae family. Didymopanax morototonii presents vestured and mostly scalariform pits and scalariform perforation plates in vessel members. Pentapanax warmingianus, on the other hand, does not have vestured pits and shows round or polygonal pits and mostly simple perforation plates in vessel members.
