NATIVE OF THE UNITED STATES OF 
NORTH AMERICA 
ARUNDINARIA MACROSPERMA 
THE solitary species from the United States of North America. 
This Bamboo appears to vary in height according to its geo- 
graphical position. In the Southern States it grows to from 
10 feet to 20 feet, or even 35 feet high, while in the north it 
does not exceed 10 feet. It is the typical Arundinaria described 
by Michaux. The stems are round (sometimes slightly flat- 
tened on one side at the point of branching), slender, and much- 
branched. The sheaths are purplish in colour, very persistent, 
and fringed at the top with a few rather coarse hairs. The 
leaves are about 7 inches long by 14 inch broad, the 
upper face smooth, the lower face downy, having the edges 
slightly serrated—very partially on one side. The secondary 
nerves vary from six to fourteen in number. ‘The leaves 
are rounded at the base and petiolated. The veins are tessel- 
lated. Interesting rather from the fact of its being the one 
representative of the family on the vast continent of North 
America than from any special beauty of its own. Some 
botanists divide the taller and shorter varieties into two 
species, but Munro treats them as identical. M, Marliac
