This is a publication by the Army Corps of Engineers, specifically for field inspectors in The Federal Regulatory Functions mission. It is non-technical, couched in layman’s language, but would be very helpful in identifying wetland plants.

Lawrence Mellichamp, one of the four co-editors of this little journal, was kind enough to send me a copy of it.
The American Fern Society is pleased to announce a new monograph series, PTERIDOLOGIA, which will publish monographs on ferns and fern-allies.
On October 12, 1978, I discovered a small population of Heliotropium curassavicum L., a member of the Boraginaceae, while visiting a salt spring in Cooper County, Missouri. This species normally occurs along sandy seashores and borders of fresh or saline marshes from Florida to New Mexico and Mexico, north to Delaware, and casually inland on disturbed balast.
Dioclea multiflora (T. & G.) Mohr is transferred to Galactia P. Br., sect. Odonia (Bertol.) Burkart, as Galactia mohlenbrockii nom. nov.
Floristic data and county dot distribution maps are presented for six species and one interspecific hybrid of the Apocynaceae found as native, naturalized, or adventive taxa in the Ohio flora. Included is the first report of Vinca major for the state.
Vernonia section Leiboldia (Schlecht.) Benth. & Hook. is a small, morphologically distinct group of six species ranging from south-central Mexico into Central America. In the present revision based on morphological studies of herbarium specimens, the section is treated as consisting of six species: V. arctioides Less., V. mexicana Less., V. salvinae Hemsl., V. lankesteri Blake, V. corae Standl. & Steyerm., and includes a new species, V. guerreroana S. B. Jones.
Analysis of herbarium material of Echium vulgare L. occurring in eastern North America yielded evidence against the existence of the two distinct varieties (or species) recognized in various floristic and revisionary treatments. Rather, the E. vulgare complex should be regarded as one polymorphic species with considerable random variation and numerous intergrading intermediates. Echium vulgare is much more common in eastern than western North America and occurs predominantly in limestone regions. In the East, it probably became established as a “weed” in the early to mid-nineteenth century.
A fifth subspecies of Sarracenia rubra Walter having a small disjunct range in the western Florida panhandle is herein described
