Book Description
The tribe Heliantheae is expanded to include the genera previously placed in the tribe Helenieae and many genera from the Senecioneae. Thirty-five subtribes are recognized and described, and the more than 265 genera are listed with known, validly described synonyms. A theoretical key to subtribes is provided. Various structural and chemical characteristics are reviewed, and emphasis is given to resin duct patterns, presence of fiber-sheaths in disk corollas, and patterns of striations in achenes. The Heliantheae is considered a member of the subfamily Asteroideae in a position parallel to and more advanced than the Eupatorieae.

Book Description
Flavonoids are secondary plant products that have previously been shown to be helpful in determining relationships among plant groups. This work presents comprehensively the occurrence, patterns of variation, and systematic and evolutionary importance of flavonoids in the sunflower family (Asteraceae), the largest family of flowering plants (23,000 species). It gathers together the more than 2500 reports of flavonoids in Asteraceae published between 1950 to the present and interprets these data in context of new taxonomic (especially generic) alignments. The authors discuss flavonoid patterns with reference to modern phylogenetic studies based on morphology and DNA data. This book provides, therefore, the most exhaustive synthesis and evaluation of the systematic and evolutionary import of flavonoids ever accomplished for any large family of angiosperms.

Book Description
This volume contains a complete systematic treatment of the flowering plant order Asterales. This comprises 12 families with approx. 1,720 genera and about 26,300 species. Identification keys are provided for all genera, and likely phylogenetic relationships are discussed extensively. The wealth of information contained in this volume makes it an indispensable source for all working in the fields of pure and applied plant sciences.

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).
