The pollen grains of 300 species of 71 genera of the family Myrtaceae have been examined and their characteristic features summarized in tabular form. The investigation has been mainly concerned with those species that occur in the south-west, Pacific area, particularly Australia. For comparative purposes, the pollen morphology of a limited number of South American and two South African species has been included. The significance of pollen characters for distinguishing genera and species within the family is discussed. In some instances pollen morphology has provided additional evidence for the classification of certain species as suggested by taxonomists. A provisional key to pollen grains of the genera examined has been included.

The results reported cover 12 genera of the family Apocynaceae and 12 genera of the Annonaceae. The anatomical features of these genera have been summarized for each family and the results compared with published information on the representatives of the families from other parts of the world. An artificial key has been developed for the separation of groups of genera in the Apocynaceae. This separation, however, does not conform with groupings based on botanical features. Possible affinities of this family have been discussed. In the Annonaceae separation of the genera on anatomical features has been found to be diffcult on account of the homogeneity in wood structure of the family as a whoIe.

The results reported cover 20 genera of the Cunoniaceae and the two monotypic families Davidsoniaceae and Eucryphiaceae, each closely related to the Cunoniaceae. The anatomical features of the genera of these families have been summarized. In the Cunoniaceae these results have been compared with published information on the family and with features revealed by examination of the available species from other parts of the world. A grouping of the genera of the Cunoniaceae based on their wood anatomy is given for diagnostic purposes and for comparison with botanical grouping. Anatomical relationships between the three families are discussed and points of similarity or difference between them and other families likely to be confused with them, are pointed out.

Examination of 13 genera from this area has indicated two structural groups within the timbers of the Flacourtiaceae. The wood anatomy of genera examined from areas other than the south-west Pacific area has been found to agree with these two groups. The anatomical features of each genus have been summarized and salient features set out in tabular form. From these an artificial key separating the genera, where possible, has been prepared. The grouping of the genera described based on wood anatomy is compared with the grouping of the family based on botanical features as suggested by Gilg (1925). Anatomical features separating the Flacourtiaceae from the groups of timbers with some similar characteristics have been indicated.

The results reported are the first of a series dealing with the timbers of the south-west Pacific area and cover 22 genera of the family Anacardiaceae. Based on the examination of available species, the anatomical features of each genus have been summarized and the� results set out in tabular form for comparative purposes. The relationship between botanical classification and the wood anatomy of the genera concerned has been discussed. From the information presented it is suggested that a simple card sorting key can be readily developed.

The results reported form part of the series dealing with the timbers of the south-west Pacific area and cover 32 genera of the Myrtaceae. The timbers of this family are perhaps more important, from an economic standpoint, than those of any other in the area under consideration (with the possible exception of the Dipterocarpaceae). Based on the examination of all available species, the anatomical features of each genus have been summarized and the results set out in tabular form. From these a grouping of the genera of the family has been made, which reveals one or two inconsistencies with the botanical classification as proposed by Niedenzu. Particular mention has been made of the anatomical variation in Eugenia (sens, lat.). The affinities of the described genera with those of the New World, and the anatomical differences between the Myrtaceae and the closely alIied Lecythidaceae, are discussed. Anatomical features separating the Myrtaceae from four other families with some similar features have been pointed out.

Athoracophoridae are succineoidean terrestrial slugs that constitute a distinctive faunal element of the South West Pacific biogeographic region, with representatives in New Guinea, Australia, New Caledonia, Vanuatu and New Zealand. Despite many studies on morphology, taxonomy and phylogenetic relationships since the first species description in 1832, the understanding of the diversity within the family, as reported in published literature, remains poor with regional disparities in collection and systematic effort, in taxonomic concepts, and in adherence to type concepts. The systematics of Athoracophoridae needs to be re-evaluated through a modern, phylogenetic approach to properly document infra-familial evolution and taxon diversity, advance understanding of evolutionary relationships with other Eupulmonata, and to delineate evolutionary units for conservation prioritization. A catalogue of all class-, family-, genus- and species-group names erected for or used to include Athoracophoridae over the 185 year period 1832 to 2017 is provided, as a first step towards a systematic revision. The following nomenclatural changes are made: lectotype designation for Aneitea macdonaldii Gray, 1860; lectotype designation for Janella papillata Hutton, 1879; type species designation for Amphikonophora Suter, 1897; and lectotype designation for Athoracophorus verrucosus Simroth, 1889.
