The Nagoya Protocol allows for countries to set out terms under which access may be given to their indigenous genetic resources in return for benefits from any research and development of those genetic resources. Many countries also put their own restrictions on the commercialisation of wild plants and seed. The key question that this thesis sets out to address is as follows: ‘Plant hunting for commercial horticulture and access and benefit sharing: complementary or competitive uses of wild novel plants?’ To address this question, we first undertook a literature review that revealed that there is little peer reviewed research available to address our research question. This knowledge gap is then examined in three chapters. First, we present an exploratory analysis of data from the Royal Horticultural Society’s Plant Finder to understand the relevance of Known Wild Provenance (KWP) plants to commercial horticulture and investigate whether the availability of such plants in commercial horticulture could provide any non- monetary benefits. Second, an analysis of the potential for monetary benefits to provider-countries in return for KWP plant material is undertaken using consumer preference data gathered as part of a choice experiment. Key findings show that commercial horticulture does not currently contribute to global plant conservation targets despite there being both the available plants and the potential for additional profit from the sale of such plants with which to do so. Ex-situ conservation within the country in which the plant is being sold could be offered by commercial ornamental horticulture as a non-monetary benefit in return for legal access to wild plant genetic resources. Additionally, KWP did not prove to be a strong driver for plant buyers, although there is positive value attached to the attribute by a significant segment of the buying population. Thus, the ability for commercial horticulture to provide monetary benefits is shown, however, Access and Benefit Sharing (ABS) negotiations should not be based solely on monetary benefits from the sale of plants. Third, in the 2 form of a case study, the practical application of the research is considered with relevance to the sale of a threatened plant species, Magnolia stellata, that is widely available within commercial horticulture. Using findings from Chapters 1, 2 and 3 we explore how access to wild material of M. stellata, and its subsequent commercialisation could lead to both monetary and non-monetary benefits being returned to the provider country, in this case Japan, for use towards the species’ conservation. Whilst this thesis reveals the continued relevance of the plant hunter for commercial horticulture is clear, more research is certainly required to understand how this can be compatible with ABS regulations. A step change in approach from both sides of ABS agreements is likely needed in order to enable both access and, in return, benefits from the sale of ornamental plants with KWP. 3 Acknowledgments Thank-you to Dr. David Roberts (School of Anthropology & Conservation) & Prof. Iain Fraser (School of Economics), University of Kent, UK for their supervision and support.

Manos 1,* and Andrew L. Hipp 2 1 Department of Biology, Duke University, 330 Bio Sci Bldg, Durham, NC 27708, USA 2 The Morton Arboretum, Center for Tree Science, 4100 Illinois 53, Lisle, IL 60532, USA; [email protected] * Correspondence: [email protected] Abstract: The oak flora of North America north of Mexico is both phylogenetically diverse and species-rich, including 92 species placed in five sections of subgenus Quercus, the oak clade centered on the Americas. Despite phylogenetic and taxonomic progress on the genus over the past 45 years, classification of species at the subsectional level remains unchanged since the early treatments by WL Trelease, AA Camus, and CH Muller. In recent work, we used a RAD-seq based phylogeny including 250 species sampled from throughout the Americas and Eurasia to reconstruct the timing and biogeography of the North American oak radiation. This work demonstrates that the North American oak flora comprises mostly regional species radiations with limited phylogenetic affinities to Mexican clades, and two sister group connections to Eurasia. Using this framework, we describe the regional patterns of oak diversity within North America and formally classify 62 species into nine major North American subsections within sections Lobatae (the red oaks) and Quercus (the Citation: Manos, P.S.; Hipp, A.L. An Quercus Updated Infrageneric Classification white oaks), the two largest sections of subgenus . We also distill emerging evolutionary and of the North American Oaks (Quercus biogeographic patterns based on the impact of phylogenomic data on the systematics of multiple Subgenus Quercus): Review of the species complexes and instances of hybridization.

    Welcome to our March meeting, Historians! Our next meeting is Tuesday, March 5 at 6:30 to discuss For All the Tea in China: How England Stole the World’s Favorite Drink and Changed History by Sarah Rose published in 2009. This is the story of Scottish botanist Robert Fortune who became a kind of industrial spy, or perhaps capitalist pirate, in an attempt to steal seeds from China to replant in India to grow tea for England. As Rose points out, this was a time when two world empires—China and England—fought over two flowers—the poppy and the camellia. In many ways, the story of Robert Fortune and the East India Company is a modern tale of industrial espionage and globalization. In other ways, it is a swashbuckling adventure. Sarah Rose gives context to Robert Fortune’s adventure by first giving the historical and economic background to the Chinese tea trade. We learn about the disastrous British deficit in the balance of payments between Great Britain and China due to the huge consumption of tea in Britain. The British attempted to restore balance by selling opium to China which in turn led to the Opium War. By 1848, the British are desperate. Robert Fortune had already spent several years in China studying plants, so the East India Company turned to him with a plan to steal tea seeds and the necessary expertise in growing tea and bring both to British territories in India and Ceylon. As Rose tells us, “this job required a plant hunter, a gardener, a thief, and a spy.” Fortune fit the bill.

SOME THOUGHTS I HAVE BEEN THINKING: Hollingsworth calls it a "nick", a combination that gives outstanding results whether it be in the plant or animal line. Roger Anderson has a plant that appears to be outstanding as a pod parent for the Itoh cross! 'Martha W.' produces seeds, sometimes many, when pollinated by Reath's lutea hybrid #198 — so says Roger. He came to our 1983 National Show with a good collection of pictures of Itoh seedlings, the outstanding feature of which was the great range of colors. While the flowers were mostly singles, as one would expect on young plants, the color range is perplexing though since they were developed from 'Martha W.' x Reath's #198 lutea hybrid. If any deep thinking person will come up with some logic on this strange occurrence, we will be grateful! In line with this unexpected happening, I'd like to add this thought: From Gratwick's advanced generation hybrids came #258 which is 95 x Choni (#95 is 'Red Cloud' x F2B). It has plum purple single rather large flowers. I suppose the richness of color stems from the lutea parent since it is quite different from the purple of suffruticosa.

    Kevin Walters—’Monica Conquest’ - 2000 It began in March 2019 and now two years onwards, the Reference Book Series on growing Clivias for Beginners is closed, with this 11th Edition, a Special Edition called “A Clivia Beginner’s BIBLE”. Statistics kept since the beginning in 2019 and shown in the 10th Edition in a spreadsheet shows that the interest in the written word no longer is a tradition. Society now demands quick responses to any questions they might have rather than investigate and at the same time educate themselves. Looking at the Clivia pictures on Facebook holds more interest than finding answers to their problems. I thank the Clivia Society of South Africa for their endorsement of my Reference Books in particular, the President, Glynn Middlewick. This Society plays a substantial role in continuing the profile of the Clivia Species for the benefit of many people throughout the world. The content of the Clivia Beginner’s Bible is drawn from many avenues around the world. The Bible is supported by the Ten Reference Books currently published via www.FlipBookPDF.net , and the content of the Website https://www.growingclivias.com which includes educational YouTube Videos on the care and management of Clivias.
