AUSTRALIAN TREES AND SHRUBS. 101 



seed. In Cornwall, at Menabilly and Falmouth, there are 

 many Eucalyptus trees of notable size. In the neighbour- 

 hood of Bournemouth about half-a-dozen species are met 

 with in the Public Gardens, but only one (E. Gunnii), in a 

 private garden, is in any way remarkable for its size. This, 

 according to Mr. Backhouse, is about 30ft. high, with a girth 

 of 48 inches. Owing to the widely different appearance 

 assumed by individual trees at different periods of growth 

 it is extremely difficult to distinguish from leaves alone the 

 species of Eucalyptus under cultivation in this country. 

 In most young plants the leaves are opposite, but they 

 generally become alternate as the plants become older. In 

 adult plants the leaves are quite different. In most species 

 the seed-leaves, the juvenile leaves, and the adult leaves have 

 each their own distinctive character. 



According to the researches of Mr. H. J. Elwes, F.R.S., and 

 Professor Augustine Henry, as recorded in their great work, 

 " The Trees of Great Britain and Ireland," the number 

 of species of Eucalyptus under cultivation in this country 

 that have attained large size and regularly bear flowers and 

 fruit is comparatively small, probably not more than a dozen 

 in all. These are chiefly from the highlands of Tasmania, 

 where the climate more nearly approximates that of the South 

 of England. 



SOME HARDY EUCALYPTUS. 



E. globulus. Blue Gum. Native of Tasmania, Victoria, 

 and New South Wales. This was introduced to Europe in 

 the early part of the nineteenth century, and was first 

 cultivated out-of-doors at Naples. The blue gum is perhaps 

 not absolutely hardy in any part of Britain or Ireland, but 

 it may survive many years and attain large dimensions in 

 favourable localities. In young stages of growth, on account 

 of its ornamental character, it is met with in gardens in almost 

 every part of the country. In exposed positions the trees
