 bundle; remain on the tree the year round. 



i There are in all thirty-five native pines in the United States. 

 Twenty-two hard pines, one red pine, and twelve soft pines. 

 Two foreign ; pines are extensively planted throughout the east, 

 the Scotch pine (Pinus sylvestris) and the Austrian pine (Pinus 

 austriaca). Both have their leaves in bundles of two. The 

 Scotch pine has needles from 1 to 1% inches long, stiff with 

 a grayish bloom upon them. The orange color of the bark of the 

 smaller limbs and the upper trunk is very distinctive. The 

 Austrian pine resembles the native red or Norway pine but its 

 leaves are much stiffer. They are from 3 to 5 inches long.
