Footnote 46 was not indicated in the text and so was assumed to be
associated with the text associated with E. J. Hill's account of the
species _Celtis pumila_. The last three items in the key on page 36
were renumbered as "4" appeared twice. On page 287, "Dr. Jno. A. Warder"
was changed to "Dr. John A. Warder".
Formatting of the titles for the sections listed in the Table
of Contents was standardized.
Hyphenation and æ ligature use was standardized. The [oe] ligature was
converted to oe. Small captioned text was NOT converted to UPPER CASE as
that is used in the text for the Family Headers.
