''Eucalyptus pulchella'', commonly known as the white peppermint is a flowering tree in the myrtle family, Myrtaceae. An erect, smooth-barked tree, it grows to 20m in height and is recognisable by its very narrow leaves.〔(The Unique Flora of Tasmania ), Hobart District Group of The Australian Plants Society - Tasmania Inc.〕 ''E. pulchella'' is a lowland species where it occurs on the upper slopes of well drained sites with a Jurrasic dolerite substrate in grassy or heathy open forests. Such sites typically have a north-west facing aspect with exposure to high solar insolation loads resulting in periodic drought stress. This species is locally widespread and endemic to the undulating, hilly terrain of south-east Tasmania. Eucalyptus is derived from the Greek words eu, meaning well, and kalypto, meaning to cover which refers to the characteristic operculum which acts as a cap, protecting the flowers. The species name ''pulchella'' is a diminutive of the word pulcher which in Latin means beautiful. The common name, white, refers to its smooth white trunk. ==Description==
''E. pulchella'' is an erect tree growing up to 20m in height. It has smooth white or pale grey bark except for at the base of the trunk. Juvenile and adult leaves are narrow (<8mm), linear and pale green to subglaucous in colour. ''E. pulchella'' bears the characteristic flowers and fruit of the ''Eucalyptus '' genus. The flowers have numerous cream stamens enclosed in an opercula cap which is a fusion of the corolla. As the stamens expand the operculum is forced of revealing the showy stamens. The developing buds are club shaped and the woody fruits, also known as capsules, are small, pear-shaped with a disc level to the rim and occur in umbels greater than 7.〔 The valves at the end of the capsules open to release the small(1mm), rod-shaped seed.
