| The wood anatomy of all genera of the Combretaceae (Meiostemon excepted) is described in detail on the basis of 120 samples representing 90 species from 19 genera. Additional data from the literature are added. The structural variation of the vestured pits is described and classified. There are two main types, of which the distribution follows the subfamily classification. Considering the overall wood anatomy, the recognition of two subfamilies: Strephonematoideae (Strephonema only) and Combretoideae (all remaining genera) can be supported. Strephonema stands out on account of its fibre-tracheids, type of vesturing and parenchyma distribution pattern. Within Combretoideae, one group of genera (subtribe Combretinae sensu Exell & Stace) stands out... |

| A classification of the Melastomataceae, modified on the basis of wood anatomical evidence, is discussed. Three subfamilies (Crypteronioideae, Memecyloideae and Melastomatoideae) are recognized . Astronioideae, recognized in other classifications, are abolished and their constituent genera are classified in Memecyloideae (Pternandra) and Melastomatoideae (four genera of the tribe Astronieae). Wood anatomically Melastomataceae show affinities with a number of Myrtalean families, notably with Lythraceae, Onagraceae and Myrtaceae. The wood anatomy of ancestral ‘Protomelastomataceae’ is hypothesized and a tentative phylogeny is suggested for the extant subfamilies and tribes. |

| The leaf, twig, and nodal anatomy of Alzatea, Axinandra, Crypteronia, Dactylocladus, and Rhynchocalyx is described in detail. This family, as newly delimited by Van Beusekom-Osinga and Van Beusekom, appears to be very heterogeneous, a conclusion supported by the wood anatomical diversity reported in another paper. The nodes may be simply unilacunar, unilacunar with a complete girdling trace, of the common gap (or split lateral) plus median trace type, or trilacunar. Cortical bundles may be present in addition. Further diversity is present in e.g. cuticular texture, stomatal type, hypodermal development, arrangement of vascular bundles in petiole and midrib, mechanical support of the veins, the crystal complement, foliar sclereids, and cork origin.... |

| The wood anatomy of the palaeotropical Melastomataceae is described in detail on the basis of 134 samples of 107 species from 36 genera. On the wood anatomy, three subfamilies are recognized, Memecyloideae, Melastomatoideae, and Crypteronioideae. The Memecyloideae stand out through their fibre-tracheids, the deviating fibre length/vessel member length ratio, and the scanty paratracheal to aliform parenchyma. The Melastomatoideae are characterised by libriform fibres showing fibre dimorphism and rays composed of erect, square, and weakly procumbent cells (also in Memecyloideae p.p.). The subfamily Astronioideae is abolished; Pternandra is transferred to Memecyloideae, the Astronieae fit perfectly in the Melastomatoideae. Within Melastomatoideae the tribes... |

| The wood anatomy of 127 samples of 65 species of all 18 genera of the Rhizophoraceae is described in detail; features not observed here, but recorded in the literature are added. Wood anatomically several groups can be recognized. Three distinct groups are very homogeneous, coinciding with the Rhizophoreae ( Bruguiera, Ceriops, Kandelia, and Rhizophora), the Anisophylleae ( Anisophyllea, Combretocarpus, Poga, and Polygonathus), and the Macarisieae ( Anopyxis, Blepharistemma, Cassipourea, Comiphyton, Macarisia, and Sterigmapetalum), as recognized by several taxonomists. One group, the Gynotrocheae (Carallia, Crossostylis, Gynotroches, and Pellacalyx), is rather heterogeneous. The family as a whole is wood anatomically very heterogeneous, but this diversity... |
