shorter papers. These are gathered in volumes, octavo
in size, with the publication date of each paper recorded in the table
of contents of the volume.

In the _Bulletin_ series, the first of which was issued in 1875, appear
longer, separate publications consisting of monographs (occasionally in
several parts) and volumes in which are collected works on related
subjects. _Bulletins_ are either octavo or quarto in size, depending on
the needs of the presentation. Since 1902 papers relating to the
botanical collections of the Museum have been published in the
_Bulletin_ series under the heading _Contributions from the United
States National Herbarium_.

This work forms number 222 of the _Bulletin_ series.
