This volume is a monograph of the 47 species of the Dulcamaroid clade of the large and diverse genus Solanum. Species in the group occur in North, Central and South America, and in Europe and Asia. The group is most species-rich in Peru and Brazil, and three of the component species, Solanum laxum of Brazil, Solanum seaforthianum of the Caribbean and and Solanum crispum of Chile are cultivated in many parts of the world. All species are illustrated and a distribution map of each is provided. All names are typified and nomenclatural and bibliographic details for all typifications presented. One new species from Ecuador is described. The monograph is the first complete taxonomic treatment of these species since the worldwide monograph of Solanum done by the French botanist Michel-Felix Dunal in 1852.

In his lectures my teacher Karl Mägdefrau used to say that one only becomes a real plant scientist when one enters a tropical rainforest. For me this initiation occurred in 1969 in northern Queensland, Australia, and was associated with the greatest excitement. On another level it received confirmation when I set out in 1983 together with some friends and colleagues for the first detailed ecophysiological studies of epiphytes in the wet tropics in situ in the island of Trinidad and later for similar work in Venezuela. This then promoted the idea of organizing a special symposium on "The evolution and ecophysiology of vascular plants as epiphytes" during the XIV International Botanical Congress in luly 1987 in Berlin, and to ask some of the speakers to produce chapters for a small monograph on the interesting ecologically defined group of plants "epiphytes" as presented in this volume of "Ecological Studies". The enthusiasm of the participants of the symposium giving reports and adding to the discussion was most stimulating, and it appears that epiphytes might gain well-deserved, wider consideration in the future. The cooperation with the authors of this book was very pleasant and I appreciated the new contacts established with adepts of the "epiphyte community". The chapters were organized and arranged covering first more gen eral aspects with setting the scene in Chapter 1, the evolution of epi phytism in Chapter 2 and the role of CO -concentrating mechanisms in 2 Chapter 3.

The identification of inputs and outputs is the first and probably most important step in testing and analyzing complex systems. Following accepted natural laws such as the conservation of mass and the principle of electroneutrality, the input/output analysis of the system, be it steady or in connection with perturbations will reveal the status dynamic, will identify whether changes are reversible or irreversible and whether changing the input will cause a hysteresis response. Moreover, measurements ofinput and output fluxes can indicate the storage capacity ofa system, its resilience to buffer or amplify variations of the external input, and it can identify structural changes. Therefore, to a certain extent, the input/output analysis can facilitate predictions about the ecosystem stability. The measurement of fluxes and the determination of inputs and outputs of eco systems are, in many aspects, analogous to measurements done by engineers when testing an electronic apparatus. The first step is the measurement ofthe input/output properties of the instrument as a whole, or ofvarious circuit boards, and the compari· son ofthese with the expected variations of the original design. Varying input and out· put can give valuable information about the stability and the regulatory properties of the device. Nevertheless, only the circuit as an entity has specific properties which cannot be anticipated if the individual components are investigated regardless oftheir position. Also, the instrument as a whole will have different input/output properties than its subcircuits.

Today, the world witnesses a global resurgence of interests in plant-based drugs and cosmetics. The revival of traditional health care systems, which is mainly plant-based, has several ramifications including the challenging tasks of meeting the health care needs of the ever increasing human population. Since the majority of raw material for preparing herbal medicine is exploited from the wild and also the traditional practices of medicinal plants harvesting does not remain sustainable due to commercial interests, the loss of medicinal plants is unprecedented. People across the world use medicinal plants in several health care practices, and the loss of this valuable resource has direct bearings on these traditional health care systems. This book deals with multidisciplinary approach and contains information on different aspects of medicinal plants, which can be used as guiding tools.
