WRITERS UPON EUCALYPTS. Al 
issued, discussing a portion at least of the 20 to 30 species that he then 
recognized as remaining untreated in his Kucalyptographia. That he 
did not, however, expect to bring the work upon the genus to a close 
before his death is shown by the following: *t 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 century 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 are probably 
but five 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, 135 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 Revisio Critica which he hopes to 
publish before long. Sucha publication from his pen will be of ineal- 
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 Hucalyptus globulus; some, however, are 
general, but only a few discuss the various species separately.
