THE ROMANCE OF OUR TREES 



lar to the Lombardy, its bark is nearly white. This 

 tree grows in Serbia, in the Crimea, and in Algiers; in 

 the Arnold Arboretum it has made rapid growth and 

 has proved quite hardy. 



Among Conifers of the type of growth under con- 

 sideration Pinus Strobus var. fastigiata is destined 

 to be of great importance. The original tree was 

 discovered about 1895 in a garden at Lenox, Mass., 

 and the trees now growing in the Arnold Arboretum 

 are grafts from it. This handsome tree has compact, 

 ascending branches forming a conical crown, and it 

 ought to be widely propagated by nurserymen. The 

 Scots Pine (P. sylvestris) has many seminal and 

 geographical forms and among them one (var. pyra- 

 midalis) of fastigiate habit. Of the Norway Spruce 

 (Picea Abies or P. excelsa) a great number of abnor- 

 mal forms are known and among them at least two 

 (var. columnaris and var. pyramidalis) with erect 

 branches. The parents of these are said to have been 

 found wild in the European forests. 



One of the loveliest of hardy pyramidal Conifers is 

 Douglas's Arborvitae (Thuja occidentalis var. pyra- 

 midalis), sold by many American nurserymen under 

 the name of Thuja occidentalis pyramidalis Douglasii. 

 It is a tall, narrow tree of a rich green hue, and was 

 raised some time before 1855 by Robert Douglas 

 in his nursery at Waukegan, 111. Since I have
