Another name change, was a Eucalyptus, now along with a few others that we know, have become Corymbia.
Beautiful red flowers borne in a dense corymb. Color due to the showy stamens. Like all Eucs they have a deciduous cap that is a modified perianth (sepals and petals).
Fruit is a woody capsule, generally 1" long, urn shaped with a constricted opening, ripening brown,. Easy to spot.
Stems are stout, reddish colored with small buds.
Bark is thin, gray brown in color, flaking in small bits to show off an orange-red inner bark, but one that holds its bark.
Misidentification: Perhaps another relative, Corymbia calyophylla, which is similar looking but the flowers are usually white or very light pink, and larger buds on the stems.
Location: Quite common.
