The most easily recognisable features of Eucalyptus types are its unique blossoms and fruit (capsule). Flowers have several comfortable stamens which may be light, treatment, yellow-colored, light or red; in bud the stamens are dark in a cap known as an operculum which is consisting of the merged sepals or flower petals or both. Thus blossoms have no flower petals, designing themselves instead with the many elaborate stamens.
