Boab

Its scientific name, Adansonia gregorii, comes from Ferdinand von Mueller naming it after Augustus Gregory, whose 1855 expedition camped beside the Timber Creek tree that still carries the party's carved arrival and departure dates. Derby's so-called Boab Prison Tree carries a legend, colonial prisoners held inside it, that historians have traced to a 1948 newspaper caption rather than any record; what is documented is its real use by the Nyikina and Warrwa people as shelter and burial ground. And Perth's Gija Jumulu, over 750 years old, made the longest recorded road journey of any living tree its size: 3,200km from the Kimberley in 2008, given its name by the Gija people who once stood beside it at home.
