Cassytha paniculata 080402-5197
Middle Head, at entrance to Sydney Harbour, New South Wales.
Common stem-parasite of shrubs, trees, grasses and sedges throughout coastal regions of NSW. It seems to attach its little haustoria to just about any kind of plant.
In most floras C. paniculata has been treated as a synonym of C. pubescens but in the recent (2007) vol. 2 of Flora of Australia it is restored to rank of a distinct species. But I have to confess to being uncertain whether this plant is C. paniculata, C. pubescens, or C. phaeolasia ! Close examination of a specimen in flower and/or fruit is necessary.
