Those in bold are surrounded by equal signs, =like this=. Footnotes were renumbered sequentially and were moved to the end of the section in which the anchor occurs. Footnotes [9], [11], [18], [19], [22], and [32] have multiple anchors. Obvious printing errors, such as backwards, upside down, or partially printed letters and punctuation, were corrected. Letters in reversed order and several italics mark-ups were corrected. Final stops missing at the end of abbreviations were added. Words may have multiple spelling variations or inconsistent hyphenation in the text. These have been left unchanged unless indicated below. Obsolete and alternative spellings were left unchanged. Misspelled words were not corrected. In the lists of common names, names are often run together, as in climbingmilkweed and rattlesnakefern; these were not changed. The following was changed: “small-loaved” to “small-leaved.”
