| Species diversity and local endemism is investigated in the pyrenocarpous lichen families Pyrenulaceae and Trypetheliaceae in the Malesian flora region and some peripheral regions. Species numbers in both families seem highest in Australia and Papua New Guinea, but some potentially rich regions are much undercollected. The numbers of local endemics are also highest in these areas, at least in the Pyrenulaceae, and remarkably high for lichens. Even more surprising is the near absence of species confined to two adjacent regions. |
