PINETUM DANICUM. 



397 



Near Stockliolni, in the park of the Royal Castle, Drottningholm, 

 several grand trees of this species are to be found. When paying a 

 visit there I had no opportunity of measuring them exactly, but 

 observed that I could not reach more than about half-way round the 

 stems with my arms. Some of these trees are most likely of similar 

 dimensions to the above-mentioned tree in Norway.

This variety differs from the species in having the leaves erectly 

 spreading, more dense, and of a very dark green colour when fully 

 grown, but when young of a silvery white on the upper surface. 



This kind bears considerable resemblance to P. montlcola, but the 

 leaves are less dense on the shoots, and much slenderer; the cones 

 are narrower, and of a bright green colour when young, while those 

 of P. monticola are of a dull purple.

A tree 80-85 feet in height, with a trunk 3-5 feet in diameter ; 

 low, wet clay or dry sandy soil, springing up on all abandoned 

 lands from Virginia southward, and now often replacing in the 

 southern Pine-belt the original forests of P. palustris ; in eastern 

 North Carolina rarely on low, rich swamp ridges — here known as 

 "Rosemary Pine," and attaining its greatest development and value 

 (C. S. Sargent, " Forest Trees of North America"). 



It is one hundred years since this species was described by 

 Linnaeus, and there is no reason to doubt that it was recognised and 

 described by botanists as long as seventy years before that date. It 

 was not, however, brought to England until 1713, when Bishop 

 Gompton introduced it. It is doubtless to that period, or not long 

 after, that the fine specimens at Syon House and Pains Hill are to be 

 referred. One of the latter, Loudon says, is doubtless the handsomest 

 tree of the species in Europe. Others at Kew and Whitton belong 

 to a somewhat later period ("Pinetum Britannicum ").
