Each manuscript intended as a feature article must include an abstract. The abstract should be a brief and concise statement of findings or results written as a double-spaced single paragraph. It should not include just a list of the subjects covered in the manuscript. Do not cite references in the abstract except under unusual situations. If you do cite references in the abstract, be prepared to justify your actions.
Introductory information is self evident and thus needs no heading.
Instead, place a three inch bar or line between the abstract and the first sentence of the introductory comments. If more than two authors, use Kenny et al. Use metric measurements throughout except when the English measurement is customarily used. Specimens should be placed with the holdings of academic institutions, recognized regional or national museums or herbaria. References used by the collection's cataloging system should be presented in the text.
