| The leaf anatomical diversity of the genera Baccaurea Lour. (43 species), Distichirhops Haegens (3 species) and Nothobaccaurea Haegens (2 species) (Euphorbiaceae) is described. Two species of Aporosa and three species of Maesobotrya were examined for comparison. The following characters are important for the delimitation of species: hair types, the position of the glandular areas on the leaf margin, the hairiness and size of the glandular areas, the number of epidermal layers, the presence of (mucilage) idioblasts in the epidermis, the presence of palisade parenchyma above the vascular bundles, and the birefringence of the spongy parenchyma cell walls. However, leaf anatomy did not yield characters for distinction between the five genera studied. Phenetic... |

| A revision is presented here of a group of mainly Papua New Guinea species of Medinilla Gaudich. ex DC. (Melastomataceae) peculiar for possessing a feature nearly unique for the family: leaf blades with a pair of lateral lobes at the base (‘pseudo-stipules’). This character was previously recorded for Astronidium miraculum-dei J.F. Maxwell & Veldk. (Astronioideae) from the nearby Solomon Islands. Various explanations, none satisfactory, for this phenomenon are explored. The group consists of 15 taxa, 2 previously described, 13 proposed here. The correct authorship of Medinilla is ‘Gaudich. ex DC.’, the correct name for the type species is Medinilla medinilliana (Gaudich.) Fosberg & Sachet, and not M. rosea Gaudich. ex DC., nom. superfl. Medinilla... |
