A project spanning over three decades has come to fruition with the publication of the Flora of the Marquesas Islands authored by David H. Lorence (NTBG) and Warren L. Wagner (Smithsonian Institution). This two volume, 1135 page opus is a complete account of all of the vascular plants found in the Marquesas Islands and was developed and written on a web site format. The Marquesas are a volcanic archipelago of 12 islands and numerous islets situated within the eastern part of French Polynesia, making it one of the most isolated groups of oceanic islands. This collaborative project between the National Tropical Botanical Garden, the Smithsonian Institution, and the Délégation à la Recherche de la Polynésie française is intended to further knowledge of the flora of this remote archipelago.Volume 1 (411 pages, published in December 2019) 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. Volume 1 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 exsiccatae (specimens studied) is given in the Exsiccatae section. Volume 2 (722 pages, published in September 2020) covers the dicots, dicot exsiccatae, a list of cultivated plants, a list of all literature cited, and an index to both volumes. Volume 2 comprises is richly illustrated with 252 color figures and line drawings.

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.

"For the first time full authoritative texts of Darwin's are made available, edited according to modern textual editorial principles and practice. Letter-writing was of crucial importance to Darwin's work, not only because his poor health isolated him from direct personal communication with his scientific colleagues but also because the nature of his investigations required communication with naturalists in many fields and in all quarters of the globe. Thus the letters are a mine of information about the work in progress of a creative genius who produced an intellectual revolution." --
