On the Florida trees the clusters of hairs at the base of the inner surface of 
the sepals and the hairs at the base of the style are sometimes wanting; and 
the fruit is subglobose, sometimes longer than broad or a little broader than 
long. Like the trees at Walhalla, the tomentum on the under surface of the 
leaves of the upper branches is usually rusty brown and silvery white on those 
of the lower branches. 
This linden is the common species in the neighborhood of Tallahassee and 
River Junction, and it appears to have been usually confounded in recent 
years with a tree of the higher Appalachian Mountains to which I have given 
the name of T. monticola. In the size and shape of the leaves this mountain 
tree resembles those of T. heterophylla, but the tomentum on the lower surface 
is thicker and whiter and never brown; the petioles are longer and the flowers 
are nearly twice as large; the branches are red, not yellowish brown, and the 
winter-buds are larger, more compressed, and bright red.

This is one of the most widely distributed of the American lindens, ranging 
from the valley of the Susquehanna River in Pennsylvania, where it was first 
noticed by the younger Micuavx in Lancaster County, to southern and western 
New York, through southern Ohio and Indiana to northeastern Missouri (Ilasco, 
Ralls County, John Davis, September 30, 1914 (no. 3164), southwestern Mis-
