摘要

Jonathan is a horticulturalist with a passion for Australian flora. He works for Plants of Tasmania Nursery, a specialist Tasmanian plant nursery. David is a senior horticulturalist at the Royal Tasmanian Botanical Gardens. He has a long and deep interest in banksias and Australian flora generally. Tasmania has been a bit short changed when it comes to species diversity in the Banksia genus, as with Grevillea, which is represented only by Grevillea australis in the island state. While Tasmania had atleast two other species in the past (Banksia integrifolia and Banksia kingii) we now have just two species, Banksia serrata and Banksia marginata. Banksia serrata is listed as rare in the state and has a fairly limited distribution, being confined to the Rocky Cape National Park on the north coast and Flinders Island in Bass Strait. In contrast, B. marginata has a widespread distribution. The paucity of species diversity in the Banksia genus is compensated at least in part by the huge variability in form.
