No. 242. Ulmus Floridana, Chap.—Florida Elm.—Florida. 
No. 243. Ulmus crassifolia, Nutt.—Thick-leaved Elm.—Texas and 
Southwest. 
No. 244. Planera aquatica, Gmel.—Planer-tree.—Southern States. 
This tree is found in the Southern States and in Kentucky and Tennes- 
see. It isatree of medium size, with foliage somewhat like that of the 
European Elm. Itis not a common tree, and the wood is not known to 
be applied to any useful purpose. 
No. 245. Celtis occidentalis, L.—Sugar or Hackberry.—Eastern United 
States. This tree is rare inthe New England States, but rather common 
in the southern and western ones. There are several varieties, one ot 
which is usually a low and straggling bush. In the Western States, it 
often becomes a lofty tree. It somewhat resembles the elm in foliage 
and the ash in bark. It produces a dryish kind of berry about the size 
of a pea. The wood is white, but is not considered durable. 
No. 246. Celtis Mississippiensis, Bose.—Mississippi Hackberry.—Mis- 
sissipp1 Valley. 
No. 247. Celtis reticulata, Torr.—Net-leaved Hackberry.—Texas and 
Southwest. This is a western species, occuring in Texas and the Rocky

PLATANACEA. 
No. 249. Platanus occidentalis, lu.—Sycamore; Plane-tree.—Eastern 
United States. This is probably the largest deciduous tree in the United 
States. It occurs throughout the Eastern, Southern, and Western 
States, and extends beyond the Mississippi River. In the rich bottom- 
lands of the western rivers, it sometimes attains the enormous circum- 
ference of 40 to 45 feet. It much resembles the European Plane-tree, 
and is thought to possess a richer foliage, and to afford a deeper shade. 
As a timber-tree it is of little value, as the wood is liable to warp, and 
decays early. 
No. 250. Platanus racemosa, Nutt.—California Sycamore.—California. 
This is the sycamore of the Pacitic coast, extending from Central Cali- 
fornia to Mexico. Although a large tree, it does not attain the size of 
the eastern species. The wood is said to be more valuable, receiving a 
good polish and being more durable. 
No. 251. Platanus Wrightiana, 8S. W.—Wright’s Sycamore.—Arizona 
JUGLANDACE A. 
No. 252. Juglans nigra, L.—Black Walnut.—Eastern United States. 
This tree occurs in the Atlantic States, but attains its greatest perfection 
and abundance in the valleys of the Ohio and Mississippi. It has been 
So much in request for the timber that it is much less common than 
formerly. The wood is used for the inside finish of houses, for cabinet- 
work, for gun-stocks, and many other purposes. It produees a nut 
much like the English walnut, but of stronger oily flavor. They are 
greatly relished by many persons. 
No. 253. Juglans cinerea, L.—Butternut; White Walnut.—Eastern
