We came across this remarkable and rare species quite by accident.
In eucalypts, the stamens are usually the showy part of the flower. Here they're yellow and small and the hard base to the flower (the hypanthium) is the showy part.
And to add to the strangeness, the beak is the bud cap (operculum) that covers the stamens until the flower is ready to open.
We were in transit between bush camps and speeding along a scrub-lined road through wheatfields when my companion exclaimed that there was a tree with red flowers.
The species is known only from a fairly small area in the wheatfield district north-west of Esperance.
