The life of William G. D'Arcy was unusual in many respects. His research career as a systematic botanist would be considered exceptionally productive even if begun in his twenties, rather than at age 41. In his early career he worked as an economist, and then as an entrepreneur in the British West Indies. In that beautiful locale, a fascination with the local flora gradually attracted more and more of his energy. Deciding on a career change, D'Arcy pursued master's (University of Florida) and doctoral (Washington University) degrees. He was appointed by the Missouri Botanical Garden to organize the completion of the multi-volume Flora of Panama project and simultaneously developed the first computerized database for a large flora. He rose to the rank of Curator and became an internationally recognized expert in the systematics and evolution of the large and economically important nightshade family. This volume features a collection of scientific contributions by D'Arcy's friends and colleagues that form a fitting memorial to the life of this influential taxonomist.

Petunia belongs to the family of the Solanaceae and as such is closely related to important crop species like tomato, potato, eggplant, pepper and tobacco. With around 35 species described it is one of the smaller genera and among those there are two groups of species that make up the majority of them: the purple flowered P.integrifolia group and the white flowered P.axillaris group. It is assumed that interspecific hybrids between members of these two groups have laid the foundation for the huge variation in cultivars as selected from the 1830’s onwards. Petunia thus has been a commercially important ornamental since the early days of horticulture. Despite that, Petunia was in use as a research model only parsimoniously until the late fifties of the last century. By then seed companies started to fund academic research, initially with the main aim to develop new color varieties. Besides a moment of glory around 1980 (being elected a promising model system, just prior to the Arabidopsis boom), Petunia has long been a system in the shadow. Up to the early eighties no more then five groups developed classical and biochemical genetics, almost exclusively on flower color genes. Then from the early eighties onward, interest has slowly been growing and nowadays some 20-25 academic groups around the world are using Petunia as their main model system for a variety of research purposes, while a number of smaller and larger companies are developing further new varieties. At present the system is gaining credibility for a number of reasons, a very important one being that it is now generally realized that only comparative biology will reveal the real roots of evolutionary development of processes like pollination syndromes, floral development, scent emission, seed survival strategies and the like. As a system to work with, Petunia combines advantages from several other model species: it is easy to grow, sets abundant seeds, while self- and cross pollination is easy; its lifecycle is four months from seed to seed; plants can be grown very densely, in 1 cm2 plugs and can be rescued easily upon flowering, which makes even huge selection plots easy to handle. Its flowers (and indeed leaves) are relatively large and thus obtaining biochemical samples is no problem. Moreover, transformation and regeneration from leaf disc or protoplast are long established and easy-to-perform procedures. On top of this easiness in culture, Petunia harbors an endogenous, very active transposable element system, which is being used to great advantage in both forward and reverse genetics screens. The virtues of Petunia as a model system have only partly been highlighted. In a first monograph, edited by K. Sink and published in 1984, the emphasis was mainly on taxonomy, morphology, classical and biochemical genetics, cytogenetics, physiology and a number of topical subjects. At that time, little molecular data was available. Taking into account that that first monograph will be offered electronically as a supplement in this upcoming edition, we would like to put the overall emphasis for the second edition on molecular developments and on comparative issues. To this end we propose the underneath set up, where chapters will be brief and topical. Each chapter will present the historical setting of its subject, the comparison with other systems (if available) and the unique progress as made in Petunia. We expect that the second edition of the Petunia monograph will draw a broad readership both in academia and industry and hope that it will contribute to a further expansion in research on this wonderful Solanaceae.

Vegetables contains reviews in 12 chapters contributed by 31 authors from 10 countries. The impressive work that has been done on most of these crops is presented in this volume. Genome projects already initiated on vegetable crops, particularly on Solanaceae and Brassicaceae species, may ignite further interest in other vegetables as well.

In 1912 Heinrich Schenker contracted with the Viennese publisher Universal Edition to provide an 'elucidatory edition' (Erlerungsausgabe) of Beethoven's last five piano sonatas. Each publication would comprise a score, newly edited by Schenker and using the composer's autograph manuscript as principal source, together with a substantial commentary combining analytical, text-critical and performance-related matter. Four of the five editions appeared between 1913 and 1921, but that of the 'Hammerklavier' Sonata, op. 106, was never published. It has generally been assumed that this was simply because Schenker was unable to locate the autograph manuscript, which remains missing to this day. But as Nicholas Marston shows in a detailed history of the Erlerungsausgabe project, other factors were involved also, including financial considerations, Schenker's health concerns, and his broader theoretical ambitions. Moreover, despite the missing autograph he nevertheless developed a voice-leading analysis of the complete sonata during the years 1924-1926, a crucial period in the development of his mature theory of tonal music. Marston's book provides the first in-depth study of this rich analysis, which is reproduced in full in high-quality digital images. The book draws on hundreds of letters and documents from Schenker's Nachla it both adds to our biographical knowledge of Schenker and illuminates for the first time the response of this giant of music theory to one of the most significant masterworks in all music.

This book provides an overview of current issues in variation and gradience in phonetics, phonology and sociolinguistics. It contributes to the growing interest in gradience and variation in theoretical phonology by combing research on the factors underlying variability and systematic quantitative results with theoretical phonological considerations. Variation is inherent to language, and one of the aims of phonological theory is to describe and explain the mechanisms underlying variation at every level of phonological representation. Variation below the segment concerns articulatory, acoustic and perceptual cues that contribute to the formation of natural classes of sounds. At the segmental level there are grammatical differences in the production and perception of contextual variation of segments and in the syntagmatic constraints on the combination of segments. At the suprasegmental level the mapping of tones to grammatical functions and vice versa is discussed. Further aspects addressed in this book are factors outside of language: Variation that arises as a result of a particular dialect or of belonging to a certain age group, or variation that is the consequence of language change. Gradience and variation have always been a central issue in phonetic and sociolinguistic research. Gradience introduces variation in phonology as well. If a phonetic entity can be pronounced in different ways, depending on the environment, prosodic factors or dialectal influences, this ‘gradience’ may introduce ‘variation’, which we understand as a stable state of grammar.
