FOREWORD. 



The planting of trees of various species of Eucalyptus 

 in California has been carried on since January, 1856, 

 when Mr. C. L. Reimer successfully introduced 14 species. 

 During all this time neither nurserymen nor the general 

 public have had any work on this genus by which they 

 could identify the various species. Everything depended 

 on the seedsmen primarily and in a secondary way on 

 the accuracy of the records of planters. From mistake 

 in both these respects the greatest confusion and uncer- 

 tainty has arisen. Of the large number of useful species 

 introduced into California but three or four are certainly 

 and general!}' known today. The botanical works cover- 

 ing this genus are inaccessible to the public on account 

 of their great cost. There are only three copies of the 

 Eucalyptographia and two of Bentham's books in this 

 State, as far as I know. The importance of this genus 

 as producers of kino, oils, timber and fuel, for ornament 

 and the reclamation of waste places and for the probable 

 sanitary effects of several of the species together with 

 the rapidity of growth of nearly all and the remarkable 

 adaptability to the major portion of California makes a 

 means of identification a want that should be supplied. 



Baron Ferdinand Von Mueller has, in the broad spirit 

 of a true scientific man, given me the use of his great 

 work on this genus, even to copying the plates.
