Eucalyptus
Eucalyptus is an evergreen tree with a height of usually 10 meters, sometimes larger than 15 meters. Leaves are lanceolate, 30cm long, covered with white powder and scent. The flower is rusty white and blooms in spring. The flowers have many operations, which extend out of the flower, with a well-developed flower bud at the bottom of the calyx. The fruit is the development of this flower jaw, and the seed is made in the fan groove of the fruit. Australia is the origin, and leaves are eucalyptus oil.
