9. Eucalyptus acervula, Miquel. Tasmania, Victoria, New South Wales, South 



Australia, and Queensland. See p. 1645. 

 Young branchlets green, terete. Leaves lanceolate, or ovate-lanceolate, 4 in. 

 long, i^- in. broad, usually straight, dull green, often undulate in margin. 



10. Eucalyptus vernicosa, J. D. Hooker. Tasmania. Seep. 1646. 



Young branchlets green, angled. Leaves alternate or sub-opposite, narrowly 

 ovate or elliptical, | to 2 in. long, \ to 1 in. broad, very thick and coriaceous, 

 shining as if varnished on both surfaces. 



f f Leaf-margin distinctly crenate. 



11. Eucalyptus Muelleri, T. B. Moore. Tasmania. Seep. 1647. 



Young branchlets reddish. Leaves usually straight, lanceolate, 3 to 4 in. 

 long, f to 1 in. wide, thick in texture, shining polished green on both surfaces. 



12. Eucalyptus urnigera, J. D. Hooker. Tasmania. See p. 1649. 



Young branchlets green, tinged with red. Leaves ovate-lanceolate, 3 to 

 3^ in. long, 1 to 1 \ in. broad, often falcate, thick in texture, dull yellowish 

 green. (A. H.) 



Cultivation 



If one may judge from the numerous references in horticultural literature to this 

 genus, none has been more persistently tried in various parts of the country ; and 

 yet when we come to record the small number of trees which have endured our 

 climate for more than a few years, it must be acknowledged that none has proved 

 more disappointing. Even in those parts of the south and west where the ther- 

 mometer only falls to 15 or 20 Fahr. at long intervals, not more than a few species 

 have long endured, and possibly the absence of summer heat is the cause, quite as much 

 as the cold and damp of winter. Though the Eucalypti seem indifferent as regards 

 soil, and grow for a few years with great rapidity, yet with some exceptions they are 

 short-lived, and die off suddenly after an inclement season, or blow down, when they 

 become tall enough to be exposed to gales. 



No one in England seems to have tried to graft the more tender species on 

 stocks of the hardier ones, though, judging from 'experience in other genera, it might 

 be possible to do this successfully. 1 On account of their leaves, flowers, bark, scent, 

 and habit, all so unlike those of any European trees, they form an attractive feature in 

 gardens and pleasure grounds ; and are so easy to raise from seed, that the certainty 

 of their death after a few years will not deter gardeners from planting them. 



A great many species have been tried at different times in the open in the British 

 Isles; but only a few have proved hardy even in the mild climate of the south and west ; 

 and the only really large and old trees which have survived are those at Powderham, 

 Penmere, Garron Tower, and Whittingehame. The Whittingehame hybrid is perhaps 

 the hardiest of all, and is the only species which has succeeded out of doors at Kew. 



1 In Gard. Chron. xxv. 145 (1899) an interesting article on this question will be found, largely taken from a paper by 

 M. Felix Sahut in the Annates de la Sociitt a" Horticulture de VHerault, which should be consulted by any one wishing to 

 propagate Eucalypti by budding or grafting.
