WRITEKS UPON EUCALYPTS. 21 



issued, discussing- a portion at least of the 20 to 30 species that he then 

 recognized as remaining untreated in his Eucalyptographia. That he 

 did not, however, expect to bring the work upon the genus to a close 

 before his death is shown by the following: " The author can not hope 

 during the remaining brief period of his lifetime to complete the 

 present work with some approach to exhaustiveness of the subject." 

 Though he continued working on the genus during much of the 

 remaining fourteen years of his life, no additional parts were issued. 

 The great man had devoted, with remarkable energy and enthusiasm, 

 nearly half a centuiy to the study of the genus, without exhausting 

 the subject or completing a work that purported to cover it. Unfor- 

 tunately the Eucalyptographia is now out of print, and it is prac- 

 tically impossible to secure a copy by purchase. There arc probably 

 but live copies of the work in America, with little possibility of the 

 number ever being increased. 



The fullest treatment of the genus Eucalyptus from the botanical 

 standpoint is to be found in Volume III of the Flora Australiensis, 

 by Bentham and von Mueller, published in 1866 by L. Reeve & Co., 

 London. This volume contains botanical descriptions of all the species 

 then known, 185 in number. The common colonial names of a large 

 number of the species are given, and the part of Australia in which 

 each species was reported as growing is stated. 



Rev. William Woolls, of New South Wales, is the author of two 

 works containing much information concerning the genus: A Con- 

 tribution to the Flora of Australia; The Genus Eucalyptus, and The 

 Plants of New South Wales. J. Ednie Brown, in New South Wales; 

 I. G. Luehmann, in Victoria; A. W. Howitt, inGippsland, and Walter 

 Gill, in South Australia, have each contributed to the literature of the 

 subject. 



Mr. Joseph H. Maiden, director of the botanical gardens at 

 Sydney, New South Wales, and Mr. F. Manson Bailey, colonial 

 botanist, Brisbane, Queensland, are actively engaged in work upon 

 the genus. Mr. Maiden is in a sense continuing the work of Baron von 

 Mueller. His papers upon the Eucalypts as timber trees in Australia 

 and upon the new species that he, in conjunction with Henry Deane, 

 has detected, are very valuable. Maiden writes that he is at present 

 engaged upon the manuscript of a B-evisio Critica which he hopes to 

 publish before long. Such a publication from his pen will lie of incal- 

 culable value to students of the Eucalypts. and will undoubtedly do 

 much to remove the confusion that now exists concerning the names 

 of many species. His descriptions already published, both botanical 

 and popular, are models of clearness, conciseness, and completeness. 



The French have been prolific writers upon the culture and uses of 

 the Eucalypts. but their articles are usually brief. Most of their pub- 

 lications treat especially of Eucalyptim' globulus , some, however, are 

 general, but only a few discuss the various species separately.
