A revision of the Viscaceae of Australia.

Abstract

The Australian Viscaceae comprise 3 genera, Viscum, Notothixos and Korthalsella, and 14 species. A further 2 species of Korthalsella are endemic to Norfolk and Lord Howe Islands respectively. None of the genera and only 7 of the species are endemic to Australia. Three species are described as new, viz. Korthalsella emersa, K. grayi and K. leucothrix. One subspecies is described as new, viz. K. rubra subsp. geijericola. There are 2 new combinations, viz. K. japonica subsp. brassiana (K. brassiana Blakely) and Viscum whitei subsp. flexicaule (V. flexicaule Barlow). The biogeographic history of the family in the Australian region is briefly discussed.
