109 EUCALYPTUS GLOBULUS 



ascending there into the colder altitudes. Valley-sides and the 

 moist slopes of wooded hills are its favourite situations. It flowers 

 in Tasmania in November and December. 



The tree is now very familiar in Europe and America, and 

 indeed throughout the world, having been of late years very 

 extensively cultivated, especially in the Mediterranean region. 

 Yet it was not introduced till 1856, when seeds were sent to 

 Paris. Specimens may now be seen commonly enough in 

 England, where, however, except perhaps in the West of Ireland 

 and Cornwall, it cannot support the winter without shelter. 

 Indeed, it is very sensitive to frost, and less hardy here than 

 some other species of the genus, notwithstanding that its very 

 restricted southern range in Australia would lead one to expect 

 greater hardiness. It has flowered in the open air at Wexford. 

 Throughout the south of Europe it flowers and fruits abundantly, 

 producing ripe seed, but even there is sometimes cut off by frost. 

 The growth of the plant is extraordinarily rapid both in height 

 and girth of stem. 



The remarkable structure to which the name of ' operculum ' 

 is given is usually considered to represent the petals, soldered 

 together and much modified. In the present species and in 

 many others there has been observed at an early stage a thin 

 outer operculum, which soon falls away and is regarded as the 

 limb of the calyx. 



The fruit varies considerably ; the typical button- shape is often 

 departed from ; and Baron von Mueller has described Australian 

 varieties where it is also very much smoother and smaller than as 

 above described.
