92 LARGE LEAVED LINDEN, OR LIME. 
cous. The largest leaves I have seen are about 6 or 7 
inches long, and 3 to 5 broad. In the young state, the 
white pubescence beneath is most conspicuous when 
the leaves are thinly covered, the hairs are stellate, the 
serratures are strong and sharp, with acuminated rigid 
points, the upper surface is dark green; the base of the 
leaf varies considerably, sometimes it is sinuated, at 
other times perfectly flat and truncated; the leaves are 
always very oblique at the base. The flowers are some- 
what larger than those of T. americana, and the fruit is 
villous, nearly spherical, and certainly always without 
any ribs.

to change his name, and we propose to call it Tilia 
Michauxii, (Michaux’s Lime,) if his plant should indeed 
prove to be any thing more than a smoother variety 
of our T. heterophylla.

GENERAL OBSERVATIONS. 
The Lime has long been a favourite tree for avenues 
and public walks; it is planted in the streets of some of 
the principal towns of France, Holland and Germany, 
and it is used for forming avenues both on the continent 
of Europe and in Great Britain. It has of late years 
been much planted along the streets in several towns and 
cities of the United States, but in Philadelphia it is so 
much attacked by insects that it probably will not long 
survive. The species employed for this purpose appears
