NOTES ON EUCALYPTUS. 227 



2. With E. gomphocephala, DO. " Local opinion gener- 

 ally classes it as a Tuart," (correspondent of Mr. Andrews). 

 Figures of jE. gomphocephala can be seen in the " Euca- 

 lyptographia " and at Plate 92, Part xxiv, of my "Critical 

 Revision of the Genus Eucalyptus " in the press. The 

 affinities are not close, the swelling of the operculum in 

 E. gomphocephala is a very prominent character, and there 

 is only the trace of a swelling observable in the buds of the 

 new species (they are, however, unripe). Occasionally, 

 e.g. at fig. 2 f. of the plate quoted, the rim of the fruit of 

 E. gomphocephala may be reduced, in which case the fruit 

 bears some resemblance to that of the new species. But 

 it would appear that the fruit of E. gomphocephala always 

 has exserted valves. The resemblance of the leaves is not 

 specially close. 



When I get flowers I will again raise the question of the 

 affinities of this tree ; in the absence of them, any conclu- 

 sions must be of a provisional nature.

 mediate in character between a "Stringybark" and a
