Phebalium daviesii

The St Helens Wax Flower (also known as Davies' Wax Flower) is a small flowering shrub native to Tasmania, Australia. The plant is only found in a small area near the George River on Tasmania's north-east coast. The plant was actually assumed to be extinct until it was rediscovered in December 1990, although fewer than 40 plants exist in the wild. The species is considered a critically endangered species within Australia, however the IUCN does not list the species as endangered.

In 2001, each Australian state nominated a native flower as a floral emblem to celebrate the centenary of the Federation of Australia. The St Helens Wax Flower was the Tasmanian Federation Flower.
