61. Remarks on the Groivth of a pecidiar Fir resembling the Vindster, By Sir 



C.Lemon, Bart., M.P., F.H.S. 



The plant in question is a pine, not a fir. It is a variety of the Pinaster, 

 characterised by the form and position of the cone, and the effects of the 

 jgrowth of the tree resulting from that position. In the common Pinaster, 

 ' the cone is oblong, tapering towards the base, and having large projecting 

 echinate scales, with deep fissures between them. In the kind in question it is 

 smaller, more ovate, tapering but little towards the base, and having moderate- 

 sized unarmed scales with shallow furrows between them. The 

 position of the cone is a still more striking distinction. In the 

 common Pinaster, the cones, of which there are generally three 

 or four, are situated behind the shoots of the whorl, and in the 

 mature state point backwards. In this obscure species, on the 

 contrary, the cone is single, and it as universally occupies the place 

 of the leading shoot, the side shoots being 

 behind it. The necessary consequence of 



this position is, that the tree can have no 



regular leader, Ijut each year one of the side 



shoots strengthens and continues the growth 



for the ensuing season. The year following, the same process 



is repeated in another direction ; a new axis of growth is formed, 



and the stem of the tree acquires a zigzag appearance, which is 



never entirely lost, though of course much obliterated by age." 



These distinctive characters. Sir C. Lemon observes, may indicate 

 a distinct species ; 2d, a hybrid, between adjacent species ; or 3d, an 

 dental, perhaps permanent, variety,"
