and where picturesqueness is desired in bold, wild lansdcape, rather

 trees in large parks, although in later life they lose their formality. 



The one mostly planted is — 



L. decidua Mill. (43) (Europoea), from Europe: a medium-sized moun- 

 tain tree, apt to suffer in the lowlands unless compensated in the soil for 

 our drouthy atmosphere, although otherwise not selective as to soil; it

 fitted. It is easily transplanted, but should be planted early in 

 spring, as it buds out very early.

 the European, being a tree of the swamp; less dense and compact in 

 growth, less graceful and symmetrical in form, with shorter foliage. 

 It is adaptive to wet places, and is best used in open groups. Unfor- 

 tunately this species is subject to a destructive sawfiy, which also attacks 

 other larches. 



The other American larches, L. Lyallii Pari. (45), a small tree from 

 timber-line of the northern Rocky Mountains, and L. occidentalis Nutt 

 (46), Western Larch, a tall tree (up to 250 feet) of the arid eastern
