Biosystematic studies on the Rubiaceae have a long tradition at the Institute of Botany in Vienna. Within this family the Anthospermeae, and especially its African and Madagascan members, are of particular interest because of several aspects in their evolution: I) Perfection of anemophily within an otherwise nearly exclusively zoophilous family; 2) transitions from hermaphrodity to polygamy and finally dioecy; 3) differentiation from large and long-lived shrubs to short-lived herbs; 4) adaptive radiation from humid to seasonally dry, fire-exposed and xeric habitats. However, morphological diversity linked to sexual differentia tion, modificatory plasticity, and eco-geographical polymorphism have for a long time hampered our understanding of the relationships among these African Anthospermeae. Thus, it was imperative to put special emphasis on field observations and to carry out a variety of experiments with cultivated plants in addition to the analysis of an enormous herbarium material. The author, for this reason, carried out extensive field work, often under very adverse conditions, and covered most African countries from Ethiopia to Southern Africa and twice visited Madagascar. In this way a multitude of data was accumulated on the group in respect to germination and growth form, vegetative and reproductive morphology, anatomy and biology, embryology, karyology, crossing relationships, phytochemistry, distribu tion and ecology, etc.

Seeds are a vital part of life on earth. They are fundamental for plant reproduction, and many seeds play an important role in the diet of man and domestic and wild animals. Knowledge of the appearance of seeds - seed morphology - is of great importance to botany and seed identification in relation to: seed setting, quarantine work, forensic work, seed poisening, studies of seed dispersal, seed banks and archaeological studies.;This bibliography contains 3775 references and is divided in two parts: handbooks, and articles and monographs. In the latter the bibliographical reference is supplemented by information of importance to seed identificaiton: genera mentioned in articles, keys, descriptions, drawings, photograph, scanning electron micrographs, anatomy and chemical methods. The index of authors contains the names of an extensive number of authors, cited in the bibliography, and in the index of genera more than 3900 genera, described in one or more of the publications are cited.

Armen Takhtajan is among the greatest authorities in the world on the evolution of plants. This book culminates almost sixty years of the scientist's research of the origin and classification of the flowering plants. It presents a continuation of Dr. Takhtajan’s earlier publications including “Systema Magnoliophytorum” (1987), (in Russian), and “Diversity and Classification of Flowering Plants” (1997), (in English). In his latest book, the author presents a concise and significantly revised system of plant classification (‘Takhtajan system’) based on the most recent studies in plant morphology, embryology, phytochemistry, cytology, molecular biology and palynology. Flowering plants are divided into two classes: class Magnoliopsida (or Dicotyledons) includes 8 subclasses, 126 orders, c. 440 families, almost 10,500 genera, and no less than 195,000 species; and class Liliopsida (or Monocotyledons) includes 4 subclasses, 31 orders, 120 families, more than 3,000 genera, and about 65,000 species.This book contains a detailed description of plant orders, and descriptive keys to plant families providing characteristic features of the families and their differences.

Secondary pollen presentation is presentation of pollen to vectors by structures other than anthers, either passively or via a specialized protection and delivery system. The main part of the book describes secondary pollen presentation genus-by-genus in 25 families. The subject has never been extensively reviewed, although secondary pollen presentation occurs in the largest family of flowering plants, the Asteraceae (Compositae), and a large family of great economic importance, the Leguminosae. Now material from the scattered literature is brought together and supplemented with original observations. Many species are illustrated and each family is individually discussed. The last two chapters provide an overview of the whole topic. All the main functions that secondary pollen presentation may perform can be carried out in other plants without it. It is concluded from this that the evolution of secondary pollen presentation has been subject to constraint and canalization. The floral biology of most plants with secondary pollen presentation has not been adequately studied. Appendix 1 points to a wide range of topics on which research at various technical and academic levels is needed. The book should also become a reference work for morphologists, systematists, and floral ecologists.
