Is eucalyptus the same as the eucalyptus tree?

The eucalyptus tree (Eucalyptus robusta Smith), also known as the eucalyptus tree, is the collective name for plants of the genus Eucalyptus in the family Myrtaceae. It is an evergreen tall tree, with about six hundred or more species. It is an evergreen plant, with periodic leaf shedding within a year; most varieties are tall trees, a few are small trees, and very few are shrub-like. Crown shapes include spire-shaped, multi-branched and weeping forms. The leaves are simple, entire, leathery, and sometimes covered with a thin waxy layer. The leaves can be divided into three types: juvenile leaves, intermediate leaves and mature leaves; the leaves of most varieties are opposite, relatively small, and heart-shaped or broadly lanceolate.
