The Proteaceae are a diverse group of plants dating back to the Cretaceous Period, now dispersed among the southern continents by the break-up of the Mesozoic continent Gondwana. New data on modern and fossil pollen will be gathered using light and electron microscopy. For the first time, the ancestor- descendant relationships within the family will be assessed by combining pollen data with information on the morphology, anatomy, and cytology of the whole plants. The proposed research will expand our understanding of the evolution and geographic history of the family during continental drift, and will clarify its relationships with other families of plants. The use of multiple datasets in assessing relationships will also illuminate the process of character evolution.

山龙眼科是一个多样化的植物群，其历史可以追溯到白垩纪时期，现在随着中生代冈瓦纳大陆的分裂而分散在南部大陆。 有关现代花粉和化石花粉的新数据将使用光学和电子显微镜收集。 首次通过将花粉数据与整个植物的形态、解剖学和细胞学信息相结合来评估家族内的祖先-后代关系。 拟议的研究将扩大我们对大陆漂移期间该科的进化和地理历史的理解，并将阐明其与其他植物科的关系。 在评估关系时使用多个数据集也将阐明角色进化的过程。
