Monserrate 1885 describes "Dryandra argentea" as growing in Dr. Cargill's Bed. This is proving difficult to track down.
One possibility would be Banksia argentea (R.Br.) Kuntze which is an incorrect name for the plant now classified as Pimelea argentea R. Br. but there are no references to this combination linked with Dryandra. Seems unlikely.
All Dryandras are confined to South West Australia. Modern classification places them within the genus Banksia. There is a long history of cultivation, firstly introduced in the early years of the 19th century.
