Commonly known as Spircea Filipendula. One of the plants 

 called Meadow Sweet. 



3. palmata, Focke (Spircea palmata, Pall. Filip6n-

 2-3 ft.: Ivs. whitish tomentose beneath or glabrous; 

 terminal Ifts. 7-9-parted; stipules large, semi-cordate: 

 fls. pale pink at first, changing to white: akenes 5-8. 

 July. Siberia, Kamschatka and Sacchalin. This spe-

 this genus. It is also sometimes grown in pots and 

 forced. Var. alba, Hort., has white rts. and var. ele-

 several lateral Ifts. ; the latter is said to be a hybrid.

tJLMTJS (ancient Latin name of the Elm). Urticdcea, 

 tribe Ultnece. 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 U. eras si folia and alata are tender ; U. 

 parvifolia and U. serotina are of dotibtful hardiness, 

 although they have persisted near Boston. The Elms 

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

 able for park planting and for avenue trees, espe- 

 cially U. Americana, which is the favorite tree for 

 street planting and as a shade tree for dwelling houses 

 in the northeastern states. It is the most characteristic 

 tree of this region and one of the most beautiful. Its 

 habit is at once majestic and graceful, and the wide- 

 spreading head, borne usually at a considerable height 

 on a straight and shapely trunk, affords ample shade 

 and shelter. Besides the American Elm several other 

 species are used as avenue trees, as Ulnntu fulva, ra- 

 cemosa and the European U. campestris and scabra. 

 Of U. campestris, thevars. Clemmeri, Comubiensis and 

 regeta are among the best for street planting; of U. 

 scabra, the vars. Helgica, Dovcei and Pitteursi. In the- 

 southern states U. serotina, crassifoUa and alata are 

 sometimes used as avenue trees. There are several 

 vars. of striking and peculiar habit, as U. scabra, var. 

 fastigiata and U . campestris, var. monumentalis, with 

 narrow columnar head; U. scabra, var. horiiontalis, 

 with horizontal limbs forming widespreading tiers; U. 

 scabra. var. pendnla, with long, pendulous branches. 

 17. campestris, var. umbracHlifera, with a dense, glo- 

 bose 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-lxM-tlc, which destroys the 

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

 from doing damage, band the tninks a few feet above
