Paperback. Zustand: Very Good. First Edition. Illustrated with line drawings, maps and black and white photographs, large octavo, pp 239, paperback with very slight wear, a faint fold to the upper cover and the first page, otherwise very good. [Mentzelia sect. Bartonia (Loasaceae) is the most species-rich of the six sections of…Mentzelia. The section consists of overwintering annuals, biennials, and short- to long-lived, sometimes subshrubby perennials whose geographic ranges are centered primarily in western North America. Synapomorphies that support its monophyly include winged seeds that are horizontally positioned in capsules, seed testal microsculpture consisting of straight, wavy, or sinuate anticlinal cell walls with 4106 papillae per cell, and broadened filaments (without distal flanges) on the outermost stamens positioned opposite the sepal lobes. Monophyly of the section is well supported by molecular characters from plastid and nuclear DNA. Despite the distinctiveness of species in sect. Bartonia from those of other sections, patterns of variation within the section have led to taxonomic difficulties that have obscured our understanding of diversity within the section. We applied a phylogenetic approach with DNA sequence data, sampled widely across geographic and taxic entities, including multiple populations of putatively morphologically variable and geographically disjunct species, to assess partitioning of morphological diversity among lineages in sect. Bartonia. We identified two major lineages that diverged early in sect. Bartonia. The first lineage, clade 1, includes M. multiflora, M. humilis, M. pumila, M. laevicaulis, and relatives. The second lineage, clade 2, includes M. decapetala, M. multicaulis, M. argillosa, and relatives, many of which are subshrubby, short-lived perennial species centered geographically in the intermountain West. The lineages we reconstructed served as a basis for taxonomic revision, and our results are consistent with the recognition of 51 species, including three with varieties. This number of species is nearly twice that recognized in earlier Mentzelia monographs. Types are reviewed, and names are lectotypified as necessary. Character synopses, including taxonomically critical seed microsculpture data and floral petal and stamen shape series, distribution maps, conservation status, and taxonomic keys (including a separate key to the eight taxa that occur in Mexico) are provided for the species and varieties.].

Hardcover. Zustand: Sehr gut. Limitierte Ausgabe. Z: Limited Edition: In linen slip-case Hardcover with Box, 712 Seiten/pages, 560 farbige und s/w Abbildungen/ ills. in color and b/w - The year 2018 marks the great Birgit Nilsson s centenary. This epic book is an homage in appreciation of countless glorious performances. Her car…eer lasted almost forty years. For some twentyfive years from the late Fifties to the early Eighties she was the dominant force in the dramatic / heroic soprano repertoire and the undisputed Queen of Wagnerians of her generation, one of the all-time Greats in the history of opera. But she was by no means limited to Wagner. Her Isolde and Brünnhilde together with Salome, Elektra, Dyer s Wife and Turandot were often collectively referred to as the Nilsson repertoire .
