some are globular, others either conical or oblong, those of the globular 
form predominating.” 
The wide soil range of the persimmon indicates that these differences 
may be dependent upon soil character, at least in large measure. A warm 
soil well exposed to the sun is best adapted to the persimmon, but it is 
found on almost any kind of soil from rich bottom land to the thin soil 
of hill tops. In Lawrence and Orange counties, according to Messrs. 
Troop and Hadley, it is found in great luxuriance in red clay soil areas, 
in lands exhausted by persistent cropping and which had been abandoned 
as worthless. 
In this wide range of soil conditions it would seem possible to de- 
termine with some accuracy the effect of soil character upon this species. 
I have called attention to these variations chiefly as an intimation that 
our forest flora is much less perfectly known than its importance merits, 
and in the hope that it will direct attention to the range of variation in 
these and other species.

Of recent years great strides have been made in systematic botany, 
especially in the line of adding new determinative features to classifica- 
tion. At the present time not only external features, but also internal 
structures are used for the determination of generze and species. This 
system of classification, according to internal structure, has best been car- 
ried out in the genus Pinus. 
The first work done upon the pines with the internal structure in view,
