Book Description
T. J. MABRY and G. W AGENITZ The half-day symposium on "Multidisciplinary approaches to the systematics of Compositae", held as part of the XIV International Botanical Congress in Berlin, on July 26, 1987, was designed to complement the University of Reading Compositae Conference (1975). The latter had yielded two impressive and thorough volumes on "The biology and chemistry of the Compositae", which were edited by HEYWOOD, HARBORNE & TURNER (1977). The 1987 Berlin Symposium did not attempt to update the information from the earlier conference but instead focussed on selected new methods for investigating the systematics of the family as well as a few examples of new systematic approaches with classical methods. From mapping chloroplast DNA restriction sites JANSEN, PALMER, and MI CHAELS reported the astonishing fact that, with the exception of one group (the subtribe Barnadesiinae of the tribe Mutisieae), all investigated other members of Compositae exhibit a characteristic inversion in their chloroplast DNA, suggesting that the inversion occurred early in the evolution of the family and that at least its major part is monophyletic. Within those groups with the inverted segment, chloroplast DNA also suggests that most of the conventionally recognized tribes are also monophyletic. This lends high credit to our predecessors who laid the foundations for the taxonomic system of the Compositae. These chloroplast DNA studies have already been published and are not included here (JANSEN & PALMER 1987, 1988).

Book Description
Sixteen volumes and one supplement have now appeared in the series known as Evolutionary Biology. The editors continue to seek critical re views, original papers, and commentaries on controversial topics. It is our aim to publish papers primarily of greater length and depth than those normally published by society journals and quarterlies. The editors make every attempt to solicit manuscripts on an international scale and to see that every facet of evolutionary biology-classical or modern-is cov ered. Manuscripts should be sent to anyone of the following: Max K. Hecht, Department of Biology, Queens College of the City University of New York, Flushing, New York 11367; Bruce Wallace, Department of Biology, Virginia Polytechnic Institute and State University, Blacksburg, Virginia 24061; Ghillean T.

Book Description
The mountainous Blue Ridge, perhaps the most botanically diverse region in the eastern United States, extends for more than five hundred miles, the bulk of the area falling within eighty-five counties of five states: Virginia, North Carolina, South Carolina, Tennessee, and Georgia. The area has attracted the attention of botanists for nearly two centuries, yet no comprehensive work has previously been available that catalogs its rich floristic abundance. Addressing the needs of professional and amateur botanists interested in the Blue Ridge, B. Eugene Wofford’s guide makes it possible to identify all the region’s native and naturalized plant life--representing 161 families, 726 genera, and 2,391 species and lesser taxa. Among the flora to be found in the Blue Ridge are a number of species that have been identified as rare or endangered. The volume contains an introduction instructing readers on the use of the guide; a glossary of terms with selected illustrations; a map of the region; a key to the major plant groups; and keys to the Pteridophyte, Gymnosperm, Monocot, and Dicot families as well as to genera, species and lesser taxa. The species and lesser taxa enumeration following each genus contains the scientific name, common name or names, general habitat preferences, frequency and area of occurrence, flowering or sporulating periods, and pertinent taxonomic and nonmenclatural synonyms. The keys for identification rely primarily on easily identified flowering or sporulating material and can be interpreted by all users, from beginners and amateurs to experienced professionals.
