 In the ' Gardeners' Chronicle,' above cited, I have given in 

 detail my reasons for following the lead of those who have com- 

 bined the two reputed species of firma and bifida. Briefly, 

 it may be stated that, although the external appearance of the 

 leaves is very different, and the internal organization, as studied 

 by Bertrand, by MacNab, and by myself, yet more so, it is im- 

 possible to consider them as belonging to two different species, 

 when they are seen to be borne on different branches of the same 

 tree. This was seen by Mr. J. G. Veitch ; and his testimony is 

 confirmed by the specimens brought home by Mr. Manes. 

 A. bifida has, moreover, never been seen bearing cones. There 

 is, then, every reason to assert that the bifida form is simply the 

 juvenile immature and sterile form of the same tree, which in 

 the mature state we know as A. firma.
