Banksia ser. Spicigerae is a special group of plants within the larger Banksia family. This group includes seven different species. All of them have unique, cylindrical flower spikes. These plants can be small shrubs or tall trees.
Their leaves can grow in different ways. Some leaves grow one after another, while others grow in a circle around the stem. The flower spikes stand up straight. They have a regular shape before the flowers fully open. The individual flowers open from the bottom. The part that holds the pollen is shaped like an oval or a cone. The seeds of these plants do not have notches on their wings.
Where These Plants Live
Five of the Spicigerae species grow only in southwest Western Australia. The other two species are Banksia ericifolia and Banksia spinulosa. They are found on the east coast of Australia.
Scientists think this group might be the oldest Banksia series. This is because it developed before the dry Nullarbor Plain separated the east and west coasts.
