specimens in Kew Gardens, where most of the trees of the species show similar 

 adventitious branchlets ; at Nuneham Park, Beauport, Bayfordbury, and Tortworth. 

 A tree at Bargally, in Kirkcudbright, measured 42 ft. by 4 ft. i in. in 1904. Trees 

 at Coollattin, Wicklow, about 30 ft. high, are very thriving. 



Timber 



The wood ^ of this pine is little valued in its own country except for firewood, 

 being light, soft, and brittle ; and so far as I know is never exported. It contains 

 large quantities of resin ; and a century ago was of some economic importance in the 

 production of tar and turpentine, though when the pitch pine of the south became 

 more generally known, it was superseded by the abundant supplies yielded by that 

 tree. (H. J. E.)

This species, which is probably only a southern geographical variety of P. rigida, 

 is distinguished from the latter by its more resinous buds, and by its longer leaves, 

 usually 6 to 7, rarely 8 to 10 in. long. The cones are variable in shape, either 

 sub-globose or shortly ovoid, or elongated conical, 2 to 3 in. in length, similar in 

 position and colour to P. rigida, but with the more slender prickles usually deciduous. 

 The cones, moreover, as a rule, remain closed on the tree for several years before 

 opening and letting out their seeds. Adventitious branches are produced on old trunks.^ 



The pond pine grows in low wet flats or in sandy or peaty swamps, near the 

 Atlantic coast from Albemarle Sound southward to the head of St. John's river in 

 Florida, and occurs also, according to Roth,* on the west side of the peninsula of 

 Florida, and along the Gulf of Mexico westward to near Pensacola. In its manner 

 of growth it resembles P. Tceda, and produces similar timber, and is occasionally * 

 tapped for turpentine. It is generally found, either mixed with P. Tesda or with 

 P. Caribcea, occasionally associating in North Carolina with broad-leaved trees, and 

 is rarely seen in considerable quantity. It often takes possession of abandoned fields. 



This species was introduced in 17 13, according to Loudon,^ who mentions trees 

 about 30 ft. high, at Dropmore, Syon, Pains Hill, and Kenwood. It is probably 



' Hough, Trees N. States and Canada, g (1907), says the wood is of medium weight and hardness, with coarse conspicuous 

 grain, resinous and of a brownish red colour witli abundant lighter sapwood. It is used for coarse lumber, flooring, sills, etc. ; 

 and to some extent for fuel and charcoal. 



2 Cf. Garden and Forest, x. 209 (1897). Engelmann, loc. cit., states that felled trees or posts set in the ground sometimes 

 produce sprouts bearing primary leaves.

* According to Sargent, in Trees N. Amer. 21 (1905), but it is not mentioned by Mohr, and must be done on a very 

 small scale. 6 Encj/. Trees and Shrubs, 979 (1842).
