Bryophyte Flora of North America


NEW Guide for Contributors March 2008

LIVERWORTS: We are doing at least one species per genus, and 1 out of every 6 for large genera, whether these are illustrated elsewhere or not. Many cannot afford Schuster’s works, and FNA illos will help.

Please select a species that is otherwise un-illustrated or poorly known, or badly illustrated in the past. We particularly like rare species to illustrate.

We would appreciate semi-permanent slides with parts to illustrate circled or arrowed by pen. Or we can make slides from dry or alcohol material but this is iffy since we are not experts. A sheet of instruction for each species is valuable, including reference to a previous illustration for clarity if needed. Mostly we can figure it out.

Hoyer’s solution may work okay if you gradually soak the plant in water plus Hoyer’s. We have been using with some success glycerin jelly, which solidifies almost instantly and is then mailable. Use a well-packed box for mailing. Make the glycerin jelly with just enough gelatin to solidify so it melts easily. It can take methylene blue or other dye if necessary. You can heat the liverwort is glycerin jelly and it plumps up nicely. A vial of the plant in alcohol is necessary for the most delicate anatomy that bursts on heating (delicate hairs), but this is probably unnecessary.

DISTRIBUTION: For each species, provide the worldwide distribution.  Begin with distribution within the flora.  List provinces of Canada and states of the United States where the taxon is recorded and supported by herbarium vouchers; do not cite the specimen vouchers in the text. 

The distribution statement should contain only a list of regions.  The discussion paragraph is the appropriate location to mention doubtful records, historical occurrences, expected distributions, and restricted ranges (e.g., to one or several counties within a state, to a particular vegetation type, etc.).

Order the major regions of the world as follows:

Greenland; St. Pierre and Miquelon; Canada; United States; Mexico; West Indies; Bermuda; Central America; South America; Eurasia (or Europe; Asia); Africa; Atlantic Islands (including Macaronesia); Indian Ocean Islands; Pacific Islands (including Hawaii and New Zealand); Australia; Antarctica.

If the distribution outside the flora area is localized to specific political units that are considered noteworthy, alphabetize the countries and place them in parentheses:

Central America (Belize, Guatemala).

If the taxon occurs widely in Mexico, simply state Mexico or indicate its regional distribution (e.g., s Mexico).  If the taxon is localized to any of the 11 northern states, list them alphabetically in parentheses:

(Baja California, Baja California Sur, Chihuahua, Coahuila, Durango, Nuevo León, San Luis Potosí, Sinaloa, Sonora, Tamaulipas, Zacatecas).

Example of a fully formatted treatment. This exemplifies a final version you will be sent eventually in "galley." You don't have to format your work like this. We do that here. Just model your work after other treatments at the "R" edit level. The very best way to examine complete formatting, of course, is to look at the first volume of BFNA, published as FNA volume 28, in July of 2007.
