Distingni.-hed from the white American elm by its buJs, which are larger 

 fc.l rounder ; and which, a fortnight before their developenient, are covered 

 vh a russet down. It is less abundant than the white American elm ; and 

 t'; two species are ra^eh' found together, as the red elm requires a substantial 

 s\\, free from moisture, and even delights in elevated and open situations. 

 nje heart-wood is coarser-grained and less compact than that of U. anieri- 

 c!a, and is of a dull red tinge; whence the name of red elm. There are 

 sjill plants bearin:: the name of U. fulva, in Loddiges's arboretum ; but they 

 a scarcely, if at all, distinguishable from U. americana.

S\c. Chnr., Sfc. Leaves like those of Carpinus i?etulus L. Branches 

 earing two longitudinal corky wings. Leaves with short petioles, and 

 (isks that are oblong-oval, narrowed to an acute point, almost equal at the 

 Jase, toothed. Samara downy, bearing a dense fringe of hairs at the edge. 

 \Miclix.) A middle-sized deciduous tree. Virginia, Carolina, and Georgia, 

 ileight 30 ft. to 40 ft. Litroduced in 1S20. Flowers and samara as in the 

 ireceding species, 



['he most remarkable part of this species is, a fungous 

 aipndage, two or three lines wide, attached to the branches 

 tHughout their whole length ; from which the name of 

 alia (winged) has been given. The wood is fine-grained, 

 mie compact, heavier, and stronger than that of U. ameri- 

 c;. The lieart-wood is of a dull chocolate colour, and 

 alliys bears a great proportion to the sap-wood. There 

 aij small plants in Messrs. Loddiges's collection, which, 

 fr-i the leaves, might be taken for those of U. (c.) su-
