CLMUS (ancient Latin name of the Elm). UrticAcea, 

 tribe Flmece. Elm. Ornamental deciduous, rarely half- 

 evergreen trees, sometimes shrubby, with alternate, 

 short-petioled, serrate Ivs. and with inconspicuous, gen- 

 erally greenish brown flowers appearing mostly before 

 the leaves. Most of the cultivated species are hardy 

 north, but C. crassifolia and alata are tender ; D. 

 pa rri folia and F. serotina are of doubtful hardiness, 

 although they have persisted near Boston. The Elms 

 are mostly tall and long-lived trees and very valu- 

 able for park pl.auting and for avenue trees, espe- 

 cially F. Americiina, which is the favorite tree for 

 street planting \nd as a shade tree for dwelling houses 

 in the noitheastcru states It is the most characteristic 

 tree of this rt,.^ion and one of the most beautiful Its 

 habit IS at onte majestic and graceful and the wide 

 spreading head borne usually at a considerable height 

 on a stiaight and shapelv trunk affords ample shade 

 and shelter Besides the American Elm se\ eral other

 F. eampestris, var. umbracnlifera, with a dense, glo- 

 liose and rather small head, may be used as an avenue 

 tree for formal gardens. Several species and vars. are 

 interesting in winter on account of their branches being 



furnished with broad corky wings. The foliage of most 

 species turns pale yellow in fall, but that of the Eu- 

 ropean species remains green much longer. 



Unfortunately many insects and fungi prey upon the 

 Elm. especially on the American Elm. One of the most 

 destructive is the elm leaf-beetle, which destrovs the 

 foliage. The Canker-worm is also serious; to keep it 

 from doing damage, band the trunks a few feet above
