Spec. Char.,§c. Flowers in heads, opening before the leaves are protruded, 
and borne on branches or branchlets developed in some previous year- 
Leaf with an obvious petiole, and a disk ovate-acuminate, equal at the base, 
and serrate. A shrub, or low tree, even in 
its native country, rarely more than 20 ft. 
or 30 ft. high, and with the diameter of the 
trunk from 12 in. to 15in. The flowers 
appear before the leaves, at the ends of the 
branches, in globose heads, and upon very 
short footstalks : they are small, of a green- 
ish brown colour, and not at all conspi- 
cuous. The fruit becomes brown before the 
leaves fall: it is small, oval, inflated, and 
rough: the seed is minute. The leaf is 
much smaller than that of P. Richard?, and 
resembles that of U’lmus campéstris, except 
in being serrated with equal teeth ; it is of 
a lively green on the upper surface, and grey 
on the under one. This species is a native 
of North America, where it is found in 
Kentucky, Tennessee, the banks of the 
Mississippi, and throughout the southern 
states. It is particularly abundant in the 
large swamps on the borders of the river 
Savannah in Georgia. The wood of this 
tree, according to Michaux, “is hard; strong, and scemingly proper for 
various uses.” It is, however, not used for any purpose in America; and 
the tree is so little esteemed, that it has not received any popular name. 
It was introduced into Britain in 1816, but is rare in collections; though 
it might be readily multiplied by grafting on the elm. There are plants at 
Messrs. Loddiges’s. The price, in New York, is 1 dollar per plant. 
? P. Abelicea Schultes (Reem. et Schult. Syst. Veg., 6. p. 304., the Abelicea of Clusius) is supposed 
to belong to this genus, It is described by Clusius as being a large upright tree, with a branchy head, 
roundish deeply serrated leaves, and greenish black fruit, about the size of a grain of pepper. ‘The 
wood is hard, reddish, and possesses somewhat of the fragrance of sandal wood. It is a native of 
Crete, on the mountains ; but has not yet been introduced.
