strong smell, the stem rises about four feet, the 
leaves set on long petiols, they are five inches 
long and two broad, the fruit is of the size of a

Order VI. —Amentacea. 
387. Ulmus alba Raf. Arboreus, ramis pendulis levi* 
bus albidis, foliis oblongis, basi acutis inequali- 
bus, duplicate dentatis, supra lucidis scabriusculis, 
subtus villosis. Raf.—Orme 1. Rob. p. 520. A 
common tree about 60 feet high, with long flexible 
branches, wood white, used by wheelwrights. 
Robin thinks that it is nearly similar to what he 
calls Ulmus Americana alba , or the American 
rough leaved elm , and I strongly suspect it is the 
U. americana , var. pendula , of Aiton and Pursh, 
but at any rate it ought to form a distinct species. 
388. Ulmus pinguis Raf.—Orme 2. Rob. p. 521. Not 
described ; perhaps it is the U. fulva of Michaux, 
but I strongly suspect it to be a peculiar species, 
Robin says that it is less common than the fore¬ 
going, of a smaller size, and with smaller leaves, 
the branches more slender and more pendulous ; 
it grows in shady woods. The boiled bark af¬ 
fords a yellow and transparent mucilage, very 
thick and abundant, similar to glue, whence its 
vulgar name of Orme gras , (Fat Elm ;) this mu¬ 
cilage is used in the manufacture of indigo.
