The Australasian generic element in Malesia.

A checklist of Australasian genera in Malesia is presented. It is arranged alphabetically by families. Each genus entry is provided with concise geographic data on occurrence in Malesian islands. In the discussion various aspects of the generic list are analysed for the 209 genera, their abundance by families, how many of these genera are confined to New Guinea, the number of genera not represented in New Guinea, the decrease of Australian genera from New Guinea westwards, and the numbers of genera belonging to the various vegetation types, from the mangrove upwards to the alpine zone.
