A newly discovered population at Cape Le Grand supports Lucky Bay as the type locality of Banksia plumosa (Proteaceae)

The type gathering of Banksia plumosa (R.Br.) A.R.Mast & K.R.Thiele was collected by Robert Brown from Bay 1 (Lucky Bay, c. 35 km east of Esperance) in January 1802 (Figure 1). Over the following two centuries, further collections of this species have been made in an area from the Stirling Range and Albany eastwards to the Fitzgerald River (Western Australian Herbarium 1998–). However, B. plumosa has not been recorded again from any area east of Bremer Bay. George (1999) concluded that the type locality was in error, and that the more likely type location was in the Albany district (King George Sound), where Brown collected from late December 1801 to early January 1802 (Vallance et al. 1993).
