The wood anatomy of 35 species belonging to 6 genera of the family Caprifoliaceae indigenous to Japan is described. Intergeneric or interspecific differences are recognised in various characters, especially vessel distribution, type of perforation plates (simple or scalariform), intervessel and vessel-ray pitting, presence or absence of spiral thickenings in vessels and fibres, ray histology and fibre type (fibre-tracheids or libriform fibres).

The anatomy of the barks of 61 species of the tribe Leptospermoideae of the family Myrtaceae, principally from Australia, has been studied. The following anatomical features in particular have been described: type and arrangement of sclerenchyma, type and distribution of crystals, silica, oil glands, sieve tube type, fibre dimensions, periderm, and rhytidome. A key for the identification of the species and/or groups of species described has been derived from the bark anatomy. The bark anatomy would appear to be superior to the wood anatomy for the separation of the species of the tribe. The relationship between the bark anatomy and the taxonomy of the tribe is discussed. Support for the separation of Choricarpia subargentea and C. leptopetala from both Syncarpia and Tristania is given. Tristania neriifolia appears to be distinctly different from other Tristania spp. and re-examination of the species is suggested. Samples of Metrosideros sp. from Indonesia have been found to have the characteristics of Xanthostemon and re-examination of the genus of this species is also suggested. Oil glands have been found to be restricted to the genera Eucalyptus, Syncarpia, and Xanthostemon. Resorption of crystals has been found in the outer phloem of a number of species. Casparian thickening of the cell walls of the suberized phellem in Callistemon and Melaleuca has been confirmed.

The first description of the wood of the monotypic Madagascan genus Diegodendron is provided. The xylem of D. humbertii is characterised by short , solitary vessel elements with alternate lateral wall pitting and simple perforation plates, imperforate tracheary elements of the libriform fibre type, nearly all biseriate, imperfectly storied, homogeneous rays composed of procumbent cells only, and diffuse and diffuse-in-aggregates axial parenchyma. The specialised wood anatomy of Diegodendron supports a close alliance with both Sphaerosepalaceae and Malvales.

Menispermaceae are comprised almost entirely of lianas. Study of its wood anatomy is of interest for understanding adaptation to the liana habit. We set out here to present a general overview of Menispermaceae wood. The wood anatomy of 77 species of 44 genera, representative of an tribes and from an continents, is described. The wood of 18 of these genera was previously unknown. We observed two secondary growth types within the family: wood with successive cambia and wood with a single cambium. The distribution of these types is partly consistent with the c1assification of the family by Diels. General characters of the family are: wide rays, enlarged vessel pits near the perforation plates, and pitted tyloses. The fun range of wood anatomical diversity is given in Table 1.

The secondary xylem anatomy of trees and lianas was compared in the family Bignoniaceae. General descriptions of the family and the six woody tribes are provided. Lianas belong to the tribes Bignonieae, Tecomeae and Schlegelieae, and most have ve.ssels of two distinct diameters, many vessels per unit area, large intervascular pits, septate fibres, large heterocellular rays often of two distinct sizes, scanty paratracheal and vasicentric axial parenchyma and anomalous growth. Conversely, trees, which belong to the tribes Coleeae, Crescentieae, Oroxyleae and Tecomeae generally have narrower vessels in one diameter class, fewer vessels per unit area, smaller intervascular pits, non-septate fibres, small homocellular rays, scanty paratracheal, aliform or confluent parenchyma, and none exhibits anomalous growth. The majority of both trees and Hanas possess growth rings, are diffuse-porous, have non-solitary vessels which lack helical thickenings, and few have apotracheal parenchyma or storied structure. All species have alternate intervascular pitting and simple perforation plates.

The wood and bark structure of Leucosidea sericea and two species of Cliffortia, the South African members of the tribe Sanguisorbeae (Rosaceae) are described. These two genera share few anatomical traits (the presence of schizo-rhexigenous intercellular spaces in the cortex, almost exclusively simple perforation plates, small alternate intervessel pits, etc.) with other Rosaceae. However, Leucosidea shows a distinct storied structure of the secondary phloem and wood as well as stratification of the secondary phloem, with conductive elements and nonsclerified crystalliferous axial parenchyma arranged into alternating bands. These conditions are recorded for the first time for the family Rosaceae. In contrast to Leucosidea, two species of Cliffortia show neither storied structure of secondary phloem and xylem, nor stratification of secondary phloem.

Comparative Wood Anatomy

Qualitative and quantitative wood anatomical data are given for two narrow Queensland endemic Eucryphia species, E. wilkiei B.Hyland and Eucryphia jinksii P.I.Forst. Comparisons of wood anatomy of all extant Eucryphia taxa show that E. jinksii and E. wilkiei are distinct from each other, and other Eucryphia species. However, for both species characters relating to perforation plates, helical thickening (E. wilkiei only) and fibres are shared with the South American species, whereas the presence of crystals in the axial parenchyma is shared only with the Australian species. These data suggest that, based on wood anatomy, E. jinksii and E. wilkiei are basal among Australian species.

For the first time, the occurrence of reticulate perforation plates in Melastomataceae is reported. They were discovered in the course of a study of the wood anatomy of the tribe Microlicieae. The occurrence and frequency of the types of plates are discussed with respect to their structure, function, and environment. The reticulate perforation plates seem to be the result of parallel evolution. Some speculations are offered about their possible adaptive value.

This paper deals with the description of general, macroscopic and microscopic anatomy of Colletia paradoxa (Spreng.) Escalante, an aphyllous and xerophilous shrub from Rio Grande do Sul (Brazil). Pores of very small diameter, very short vessel elements, spiral thickenings and simple perforation plates in vessels, non sptate libriform fibers, scanty paratracheal axial paranchyma, and Heterogeneous II rays were observed in the wood.. Perforated cells are also common in rays. The presence of perforated ray cells and anatomical features of the vessel elements are discussed with respect to eco-physiological aspect of the plant and wood anatomy literature.

The wood anatomy is able to evidence systematic and ecological aspects associated with the evolution and functionality of the secondary xylem. The present study was carried out using wood of Chiococca alba (Rubiaceae) from cerrado (savannah), to describe its anatomy and to verify if the hydraulic architecture of this species corroborates the theory that postulates the functional tendency that optimizes the transport efficiency associated with safety. The anatomical analysis followed the conventional protocols of wood anatomy. Different indexes of wood hydraulics quantification were calculated, such as solitary vessels index, vessel grouping, conductivity, vessel collapse, theoretical resistance to vessel implosion and mesomorphism. The structural characteristics described for C. alba are in agreement with the general anatomical descriptions for the Rubiaceae family that relate the presence of exclusively solitary vessels and small diameter, simple perforation plates, alternate intervessel pits, apotracheal parenchyma in species with non-septate fibers and narrow and heterogeneous rays. The calculated indexes showed that C. alba is a xerophyte species with great resistance to the collapse of the vessels during the transport of water, little vulnerability to embolism and relative efficiency in the transport when compared to other species of its subfamily (Cinchonoideae) in function of the typical low water availability of the savannah soil.

The genus Carpodetus from New Zealand, New Guinea, and the Solomon Islands, traditionally has been included in the extremely heterogeneous Saxifragaceae sensu lato, but on account of morphological peculiarities it has sometimes been classified in its own family. On palynological grounds it has been suggested to belong near the Ericales. Parsimony analyses of matrices comprising rbcL sequences of 80 taxa sampled from the entire Asteridae and Rosidae provide support for a sister group relationship between Carpodetus and a clade comprising the closely related Australian genera Abrophyllum and Cuttsia, also formerly placed in Saxifragaceae sensu lato, but recently shown to belong within the order Asterales sensu lato. A morphological comparison between the three interrelated genera is provided. They have in common an indumentum of thick-walled unicellular hairs with warty cuticle, and are also uniform in wood anatomy as well as fruit and seed structure. It is proposed that the family Carpodetaceae be expanded to encompass Abrophyllum and Cuttsia.
