OLMUS (ancient Latin name of the Elm). Urtic&eea, 

 tribe Clmeie. 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 CT. crassifolia and alata are tender; U. 

 parvifolia and C. serotina are of doubtful hardiness,

furnished with broad corky wings. The foliage of most

 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, Galleruea xantho- 

 mehpna. which devours the foliage. To keep it from tlie 

 trees, band the trunks a few feet above the ground with
