Pinus Strobus nanus 



five needles in a bunch 



Pinus Strobus. the wliite pine, is well known for its 

 usefulness in big plantations ; there are some very dis- 

 tinct forms of it to isolate or to plant in beds. Str. 

 uinbraeulifera, a d^varf growing form with long silvery 

 needles; Str. nana or pygmaja, another dwarf growing 

 form, compact, with erect shoots and short needles; 

 Str. ])yraniidalis. of a narrow, straight growing habit; 

 Str. gracilis viridis has very thin green needles but is a 

 slow grower. P. monticola. the western white pine, 

 looks much like Strobus, growth more slender and of 

 dark green color: isolated on the lawn it is of good 

 effect. 



P. Balfouriana or cristata from the eastern slopes of 

 the Eocky Mountains is a curious pine; the long shoots 

 are clothed with short needles adpressed against the 

 shoots with a brush like end. It is a slow grower but 

 interesting and hardy. There are a few dwarfer and 

 stouter arowina' forms found, accordintr to the altitude 

 where they come from. 



P. Lalnbertiana, the sugar pine, is a western tree, 

 the tallest of all the American pines. It grows to a 

 high, narrow pyramid, and is a beautiful tree but does 

 not thrive very well in the East. 



P. Cembro, the European stone pine, is a very nice 

 tree for the lawn. When young it is very compact and 

 pyramidal in form; very distinct and hardy. There 



Pinus Peuce 



is a Siberian form, a more vigorous grower with slender 

 habit and shorter needles. . 



P. Peuce, or Peuke, from Macedonia, is another good 

 tree for small lawns, of a perfect dense pyramidal 

 form, very compact, dark green in color and resembles 

 cembro when young but has longer shoots, longer 

 needles, and is larger in diameter; it is said to be a 

 form of excelsa. 



P. excelsa, Himalaya pine. A noble tree resembling 

 Strobus, with longer pendant needles and a more 

 drooping habit in the branches. It is a tree which 

 wants much space as in mature specimens the branches 

 spread a great distance. 



P. parviflora comes from Japan, has short rough re- 

 curved needles of a dark grayish green color, does not 

 grow to a great size and is of an irregular spreading 

 habit; good for the small lawn. P. brevifolia is a form 

 with shorter recurved needles and is a smaller tree of 

 the same habit. 



P. pentapbylla is often mistaken for parviflora which 

 it much resembles. It is a more northern tree, how- 

 ever, also from Japan, having the same way of growing, 

 but with longer and lighter green needles.
