This new 2-volume edition of “the most significant botanical publication on Pacific plants in recent decades” (Flora Vitiensis Nova) includes an extensive addendum providing information on newly described species, nomenclatural changes, and new island records, together with a bibliography of important taxonomic references published since the first edition. The status of 271 species newly listed as endangered or threatened has also been updated.

The Flora of the Marquesas Islands is a complete account of all of the plants found in the Marquesas Islands. Of the total 826 vascular plant species recorded for the Marquesas Islands, approximately 495 are aliens introduced by humans over the years, including 248 cultivated, 33 Polynesian introductions, and 214 other naturalized species, compared to the native flora of 331 species. This is a collaborative project between the National Tropical Botanical Garden, the Smithsonian Institution, and the Délégation à la Recherche de la Polynésie française intended to further knowledge of the flora of this remote archipelago. Based on extensive fieldwork this book covers the extant floristic diversity, including 85 recently described species, and provides original illustrations, illuminating photos, and critical conservation considerations. The 411 page tome includes introductory chapters covering the project's history, Marquesas geology and climate, history of plant collecting in the islands, flora and vegetation, plant communities, threats to the flora, conservation status of species including IUCN Red List recommendations, critical conservation considerations, and many other aspects, as well as taxonomic treatments of the native and naturalized lycophytes (fern allies), ferns, and monocots. The volume is richly illustrated with 134 figures including 111 color plates, 21 elegant line drawings by Smithsonian illustrator Alice Tangerini, and two maps. A complete list of all botanical specimens studied is given in the Exsiccatae section.

The Marquesas Islands (French Polynesia) are an isolated group of volcanic hot spot islands in the SE Pacific Ocean. Intensive botanical exploration of the Marquesas for the Vascular Flora of the Marquesas Islands and Flore de la Polyn?sie fran?aise projects has resulted in numerous new collections. The nine precursor papers in this issue include three new combinations and descriptions of 18 new species and one new variety of ferns and flowering plants, bringing the total number of new species described in conjunction with these projects to 62. Most of these new species are extremely rare and localized, and they have been assigned preliminary IUCN Red List ratings of Endangered or Critically Endangered. This clearly demonstrates that field work and biological inventories are essential to enhance our knowledge of insular biodiversity and provide critical information for conservation of organisms and habitats. The Vascular Flora of the Marquesas Islands is a collaborative project between the National Tropical Botanical Garden, Smithsonian Institution, and D?l?gation ? la Recherche (French Polynesia) under the direction of David H. Lorence and Warren L. Wagner.

The Flora of the Marquesas Islands is a complete account of all of the plants found in the Marquesas Islands. Of the total 835 vascular plant species recorded for the Marquesas Islands, approximately 504 are aliens introduced by humans over the years, including 257 cultivated, 33 Polynesian introductions, and 214 other naturalized species, compared to the native flora of 331 species. This is a collaborative project between the National Tropical Botanical Garden, the Smithsonian Institution, and the Délégation à la Recherche de la Polynésie française intended to further knowledge of the flora of this remote archipelago. Based on extensive fieldwork this book covers the extant floristic diversity, including 85 recently described species, and provides original illustrations, illuminating photos, and critical conservation considerations. This work imparts a foundational knowledge of the flora as a vital component towards preserving the biodiversity of the Marquesas Islands. This is the second and final volume of the Flora of the Marquesas Islands. Volume 1 comprised the introductory chapters, Lycophytes, Ferns, and Monocots, and Exsiccatae for those groups (Lorence & Wagner 2019). Volume 2 comprises the Dicots in the traditional sense (basal angiosperms plus the eudicots), Cultivated Species Appendix, Literature Cited, Exsiccatae, and Index for both volumes.

Elements of Sonata Theory is a comprehensive rethinking of the basic principles of sonata form in the decades around 1800. This foundational study outlines a new, up-to-date paradigm for understanding the compositional choices found in the instrumental works of Haydn, Mozart, Beethoven: sonatas, chamber music, symphonies, overtures, and concertos.
