Two books published late in 1973 by the Quadrangle Press are attractive, informative, and unusual in their treatment, deserving of places on every botanist’s library shelves.
An obviously “different” Setaria, frequent as a weed on the Louisiana State University campus in Baton Rouge, has proved to be S. pallide-fusca (Schum.) Stapf & Hubb., a species widespread in warmer parts of the Old World.
The vascular plants included in this list are rare in all of South Carolina, outside of their usual geographical region within the state, or inadequately collected. Their distributions are largely based on information in the Manual of the Vascular Flora of the Carolinas (1968). Specimens of each are deposited in the Ives Her barium at Furman University. Some of the plants were collected while doing research under NSF Grant No. GB-2496 administered by High lands Biological Station, Highlands, N. C.
Twelve former oak-chestnut communities in western Virginia were sampled in 1969 to determine their composition 30 years after the chestnut blight became fully manifested in the region. Based upon overall importance values, the most important tree species were found to be Quercus prinus, Q. rubra, Acer rubrum, Q. coccinea, and Q. alba. The results of the study were found to be in general agreement with similar investigations conducted previously in other portions of the former oak-chestnut association which seem to indicate that the association can now best be regarded as an oak association-complex.
Betula uber (Ashe) Fern., a perplexing and literally unknown species first reported new to science from Virginia in 1914, has been eluding botanists for years. A recent survey of literature and field studies have brought together some previously overlooked data, but still no trace of living specimens have been found.
Dr. Joseph C. Frank (1782-1835), a German-born physician and botanist, was sent to the United States by the Wurtemberg Natural History Travelling Society, or Unio Itineraria, of Esslingen, Germany, to collect plants. Dr. Frank resided in southwestern Ohio during 1833-1835. While in Ohio he contributed to John L. Riddell’s Synopsis of the Flora of the Western States (1835) and his Supplementary Catalogue of Ohio Plants (1836) and became acquainted with other contemporary Ohio botanists. In 1835 Dr. Frank went to New Orleans, where he died of yellow fever that fall. Frank’s Ohio plants were later distributed by the Unio Itineraria, two sets of which were received by German botanists, Karl Frederick Meisner and John Jacob Bernhardi. Later these two private herbaria became part of the herbaria of the New York Botanical Garden and the Missouri Botanical Garden, respectively. Other botanists, principally Ernest Gottlieb Steudel and Carl Sigismund Kunth, each described species from Frank’s specimens. Not generally known, however, are the isotypes from the collections of Meisner and Bernhardi, which are enumerated here in an annotated catalogue of 14 species.
One hundred eighty-four species of bryophytes are reported from south and central Mississippi. Of this number one hundred twenty-two are mosses, sixty-one are liverworts, and one is a hornwort.
This paper presents the results of a taxonomic and distributional study of the family Cistaceae in Ohio. Information concerning distribution, frequency, habitat, and phenology was collected by examination of specimens from thirteen herbaria. Keys are included and taxonomic problems discussed. Distribution maps are included for the ten species found to be native to the state: Lechea (seven species), Helianthemum (two species), and Hudsonia (one species). The Cistaceae show an apparent bimodal distribution within the state. Primary areas of occurrence are (1) sandy areas of the Appalachian Plateau in eastern Ohio, and (2) sandy beach ridges of northwestern Ohio, deposited by the predecessors of modern Lake Erie.
The Eupatorieae consists of nine genera and 34 species in Virginia, of which Eupatorium with 17 species is treated floristically. The other genera have been treated previously. Three species of Eupatorium, E. cannabinum, E. mohrii and E. pinnatifidum are reported from Virginia for the first time. Dot maps showing distributions within the state are included for 16 taxa, and keys to species and comments concerning ecology, flowering and fruiting times and general distribution are included.
