TILIA, continued 



T. dasystyla. Crimean Linden. (Mm) A variety of fine form, with 

 thick, deep green, glossy foliage. The bright green bark of the younger 

 growth shows well in winter. 



T. platyphyllos. Large-leaved Linden. (L r) A broad-topped tree, 

 with foliage larger than any other variety of this family. It flowers quite early 

 in the spring. A desirable avenue or lawn tree. 



T. platyphyllos, var. aurea. Golden-barked Linden. (Mm) A va- 

 riety in which the younger growth is bright yellow, therefore distinct and 

 attractive in winter. 



T. vulgaris ; syn., Europaea. European Linden. (L m) A vigorous 

 grower, not as large as T. platyphyllos and blooms later. The foliage is smaller 

 and green on both sides. 



T. vulgaris, var. rubra. Red -barked Linden. (Mm) This variety forms 

 a dense round-topped tree. The bark on branches is a dark purplish red and 

 very showy in winter. The foliage, of medium size, is dark green. 



ULMUS. Elm 



An exceptionally desirable class of trees, requiring a rich, moist soil for their 

 best development. They are excellent lawn trees, and the American, English and 

 Huntingdon Elms are valuable for street and avenue planting. It is throughout 

 New England that we find the finest specimens, and the grand avenues planted 

 with these trees in many of the eastern cities have become so well known that the 

 Elm is always associated with New England. 



U. Americana. American Elm. (Lr) A magnificent native tree, with a 

 wide arching top and pendulous branches. The rough leaves are dull green. 

 One of the most characteristic and picturesque of American trees. 



U. campestris. English Elm. (Lm) A round -topped and sometimes 

 open-headed tree, generally densely branched. The dark green leaves remain 

 much longer in the autumn than those of the American variety. 



U. campestris, var. latifolia ; syn., major. Broad-leaved English Elm. 

 (L r) A good strong grower. The foliage larger than that of the species and 

 expands very early in the spring. 



U. scabra; syn., montana. Scotch, or Wych Elm. (L r) This forms 

 a broad, round-topped head, with heavy, spreading branches. Perfectly hardy 

 and an extremely good sort. 



U. scabra, var. Huntingdoni. Huntingdon Elm. (Lr) An excellent, 

 vigorous grower of erect habit. Bark smooth ; foliage dark green. One of 

 the best. 



U. scabra, var. pendula. Camperdown Elm. (Ds) A dwarf form, used 

 as a standard by grafting on 6- to 8-foot stems, when it forms a broad, spread- 

 ing, umbrella-shaped top. One of the best weepers. 



U. scabra, var. purpurea. Purple Wych Elm. (Mm) A neat-growing 

 form, with purple foliage. Somewhat smaller than U. scabra.
