Aims Asian tropical and subtropical mountain systems (ATSME) encompass a diverse group of complex ecosystems ranging from tropical rainforests and subtropical rainforests to alpine grassland. ATSME provide a good chance to explore the mechanisms underlying the pattern of mountain biodiversity patterns, and various hypotheses have been proposed. We aim to characterise diversification in Arethuseae and its driving factors in Asi...

Aim Flower traits are critical to the mutualistic networks that underpin ecosystem function. However, the broad‐scale drivers of flower traits are unclear. Using the megadiverse islands of Malesia, we test three hypotheses: (1) Flower size, openness and colourfulness (i.e. the trend from white to colourful flowers) will decrease with increasing temperature, but not with increasing precipitation seasonality. (2) Flower size, op...

Summary Lasjia griseifolia Utteridge & Brambach, a member of the Proteaceae, is described and illustrated as a new species from the Indonesian island of Sulawesi. The new species is similar to L. erecta , also from Sulawesi, and morphological differences between the taxa are discussed; a line illustration and detailed notes on the conservation status are provided.

Summary The Winteraceae comprise 100 – 130 species in five to nine genera. The genus Zygogynum is currently thought to have a Papuasian-Pacific distribution and is only known from the western Pacific islands (New Caledonia, Vanuatu and the Solomon Islands), Australia and New Guinea, including the far western Bird’s Head Peninsula, but is not yet recorded from islands to the west of the Sahul Plate and the biogeographic boundar...
