152 CONIFEROUS TREES 



by the severe frost last winter, P. radiata was 

 quite unharmed in inland situations. 



P. RESINOSA, Solander. (Synonym : P. rubra, 

 Michaux fit) Newfoundland, Canada, to Penn- 

 sylvania. 1756. — This species thrives in a fairly 

 satisfactory manner generally throughout the 

 British Isles. It is of open character, the branches 

 being long, and with a naked appearance, from 

 the leaves being collected in tufts at their tips. 

 The leaves are in pairs, dark green, and nearly 

 6 inches long ; while the warm, cinnamon-tinted 

 cones are each 2 inches long, and ovate-conical. 

 For planting on thin, gravelly soils, this is a useful 

 pine, and has, in this country, been found well 

 suited for mixing with such species as P. Laricio, 

 P. sylvestris, and P. Pinaster, The timber is 

 highly prized in Canada, where it is known under 

 the name of the Red Pine ; but in this country 

 the lasting properties of home-grown wood have 

 not yet been satisfactorily tested. 



P. RIGIDA, Miller, American Pitch Pine. 

 (Synonym : P. Taeda rigida, Solander.) North 

 America. 1759. — A highly ornamental and useful 

 conifer in this country, and one that is singularly 

 devoid of the stiffness and formality for which 

 many species are so remarkable. The outline of 

 the tree, as generally seen in England, when 

 allowed room for development, is somewhat after 

 the style of our native species, the branches being 

 arranged in no regular way, some assuming a 

 spreading and others a pendulous mode of growth, 

 thus showing off the warm and pleasantly tinted 

 bark. The leaves are arranged three in a sheath, 

 are from 3I inches to 4 inches long, stifiish, and
