our Eucalyptus occidentalism which for convenience I shall name 

 var. californica, varies from it in having long stalklets." The 

 var. californica is still further described in several sentences. 

 Vide E. californica, supra. 



5. E. pinnata (^auct.). "The small grey-leaved Eucalyptus 

 pinnata has grown well" (Kinney, op. cit. 117). I have never 

 seen E. pinnata further referred to in print. Specimens of E. 

 pinnata received from Mr. J. Burtt Dav-y, then of Berkeley, Cal., 

 I referred to the Tasmanian E. coed/era, Hook. 



4. Names givenvto cultivated reputed Eucalyptus Hybrids. 



Dr. Trabut, of Algiers, has during the last few years named 

 some Eucalypts which he frankly terms hybrids. Following is a 

 list of those of which I have records. I may mention that it may 

 cause inconvenience if hybrids be named just as species are, 

 without any indication attached to the name that the}'' are 

 hybrids. In the case of M. Naudin's supposed species, the case 

 is different, as he does not admit that they are hybrids; yet I 

 think that the variation of some of them, at least, is caused by 

 hybridism. 



The question of h3'bridism in Eucalyptus is an important one, 

 and considerations of space preclude discussion of it on the 

 present occasion. I am of opinion that hybridism does play a 

 part in the variation of species in the genus, and will take an 

 early opportunity in another publication of expressing some of 

 my views on the subject.

 note in Rev. Hort. de I'Algerie, Aug , 1001, p. 239. Dr. Trabut 

 in naming this plant after Dr. Bourlier, says (Rev^ Hort. Alg.) 

 " Enfin un hybride de globulus que je me propose de decrire et 

 de dedier a I'arboriculteur distingue chez lequel il a pris 

 naissance.'"'
