888 VAKIAIJILITY OF EUCALYPTUS UNDER CULTIVATION, 



Davy of Berkeley, and ^Ir. Abbot Kinne}-, of Los Angeles, 

 California, I am indebted for specimens and literature concerning 

 American grown Eucalypts; and to Mr. E. Hutchins, Conservator 

 of Forests, Capetown, and others, I am indebted for South 

 African specimens. To Dr. Prain, Superintendent of the Royal 

 Botanic Garden, Calcutta, and Mr. I. H. Burkill, of the Calcutta 

 Museum, I am indebted for much Indian grown material. Space 

 will not permit detailed reference to the many other friends from 

 whom I have received specimens of cultivated Eucalypts. 



The botanist who, above all others, has given most attention 

 to cultivated Eucalypts is the late M. Charles Naudin, Director 

 of the Experimental Station at the Villa Thuret, Antibes, 

 Southern France (Alpes Maritimes). He has published two 

 masterly works on the subject* which for the sake of brevity I 

 will henceforth refer to as 1st Mem., and 2nd Mem., respectively. 

 Both works are rare, the latter excessively so. I have had the 

 advantage of studying his specimens and of admiring the judicious 

 remarks attached by him, not only to cultivated specimens but 

 to the spontaneous Eucalyptus specimens in the Paris Museum. 



M. Naudin desires to adopt the conservative attitude in pro- 

 testing against the multiplication of species. Speaking of over 

 300 species being described at the date of 1st ]Mem., he adds, 

 p. 338 :— 



"II est reellement beaucoup moindre, et I'exageration ici 

 s'explique aisement par I'extreme variabilite des formes speci- 

 fiques; par les changements d'aspect, je dirais presque les meta- 

 morphoses que les individus eux-memes subissent en passant de 

 I'etat juvenile a I'etat adulte; par la defectuosite des materiaux 

 d'herbier, et aussi par la tendance ordinairement inconsciente de
