The taxonomic status of each of the genera within the ‘Gaultheria group of genera’ of the tribe Andromedeae (Ericaceae) has been investigated. These genera are Gaultheria L. (including Pernettya Gaud. and Chiogenes Salisb.), Leucothoë Don, Zenobia Don, Diplycosia Bl., Pernettyopsis King & Gamble and Tepuia Camp. The morphological characters have been discussed.

Quantitative descriptions of the woody flora and soil analyses are given for five areas of cerrado (savanna woodland) near Cuiabá, Mato Grosso state, Brazil. Comparisons are made of the floristic composition and community structure of these areas using polar ordination and hierarchical classification techniques.

Sarcostemma arabicum Bruyns & Forster (Asclepidaceae) is described from the Arabian Peninsula. Comparisons are made to S. socotranum Lavranos and S. viminale (L.) R. Br.

The new species Teucrium eburneum (Labiatae), from the limestone escarpment of north-east Somalia and belonging to sect. Teucrium, is described and illustrated.

Lyperia canariensis and Urbania lyperiiflora are transferred to Camptoloma Benth; Manulea antirrhinoides is transferred to Lyperia Benth., and one species of Lyperia is newly described; fifteen species and one subspecies of Sutera are newly described, and one new combination is made.

Four new species of Alpinia are described; A. glacicaerulea, A. sandsii and A. maxii, all belonging to sect. Myriocrater K.Schum., and A. amentacea, which is placed in the small sect. Eubractea K. Schum.

The lamellate boletes found in the Cooloola Sand-mass, Queensland are described and discussed in the light of earlier Australian records of paxilloid fungi. Nine species of Paxillus are discussed, two in Tapinella, which is maintained as a separate entity, and 11 are assigned to Phylloporus. Of the last, eight are new records to Australia and two are new species. Three appendices cover various aspects of studies on Australian boletes which have come to light since the publication of this series, including notes on the host-range of the parasitic hyphomycete Sepedonium.

Four Uromyces species are described as new, viz. U. astragali-alopecuri sp. nov. on Astragalus alopecurus from Turkey, U. astragali-atropilosuli sp. nov. on A. atropilosulus subsp. bequaertii var. bequaertii from Kenya, occurring also in Ethiopia and Tanzania, U. astragali-pseudoutrigeris sp. nov. on A. pseudoutriger from Turkey, and U. semnanensis sp. nov. on A. fridae from Iran. Several new hosts (marked *) are reported for U. punctatus. This rust is reported as new to S America (in Chile).
