The volume contains several large and important families, in particular Umbelliferae, Primulaceae, Gentianaceae, Asclepiadaceae, Rubiaceae, Boraginaceae and Labiatae. Among these the families Primulaceae and Gentianaceae contain many species highly valued as ornamental 'alpines' in the West; many of these species are endemic to the East Himalaya or Bhutan. ACKNOWLEDGEMENTS The editor of this volume of the Flora of Bhutan wishes to thank the following people and organisations who have contributed to its completion and have given support to the project: The authors of taxonomic accounts for their patience and understanding of the constraints which have led to such a lengthy delay in publication: Eona M. Atken, Robert R. Mill, Sally J. Rae, Lawrie S. Springate, Mark F. Watson, John R.I. Wood and Jenny Wright. It is with great sadness that we record the untimely death of Rose A. Clement (nee Gng), the author of the account of Labiatae. The Foreign Ministry of the Royal Danish Government has generously provided the much-needed funding to secure completion of the Flora, through their foreign aid programme (DANIDA). Ths part is the first to be published under ths new regme and we would like to thank those who have made this possible: Elsebeth Tarp and Nils Kjralsen in Denmark, and Margot Mraller Nielsen in Bhutan. We continue to value the support of the Royal Government of Bhutan, in particular Lyonpo Jigmi Thinley (Foreign Minister), and the Minister of Agriculture, Lyonpo Dr Kinzang Dorji and his predecessor Lyonpo Khandu Wangchuk who enabled the Flora Completion Project to become a reality. We would also like to thank staff of the National Herbarium and National Biodiversity Program for their interest and contribution of specimens and unpublished information on Bhutanese plants, in particular Karma Tshering, Rebecca Pradhan, Tandin Wangdi and Yeshey Dorji. During the period when this volume was researched and written, most of the costs and facilities were provided by the Royal Botanic Garden Edinburgh. We would therefore like to thank the following colleagues: Professor David Ingram, Dr David Mann, B.L. Burtt and H.J. Noltie. Thanks are also due to Mary Bates who has undertaken all the plates for this part. We also acknowledge the Friends of the Royal Botanic Garden Edinburgh for financial support for production of the plates. During this period consider- able additional financial assistance was provided by the Headley Trust, London; the Artois-Spoelberch Foundation, Belgium; and Mikinori Ogisu, Kamitakaido, Japan. Without their generous support the work could not have been completed. The Directors and Curators of the herbaria at the Royal Botanic Gardens, Kew and the Natural History Museum, London have continued to provide facilities for study-visits and many very large loans of specimens. The staff of these organisations are also thanked for regular taxonomic advice and assistance, as are the following specialists for advice on particular families: David Middleton (Apocynaceae), Ian Hedge (Labiatae), George Staples (Convolvulaceae), Peter S. Green (Oleaceae) and Jennifer Woods (Umbelliferae). Other botanists, horticulturists and friends who have supported the project over many years include Ron McBeath, Chris Brickell, Roy Lancaster, Keith Rushforth, Tony Schilling, Professor W.T. Stearn, Simon Bowes Lyon, Chris Parker and John Wood. Finally, the editor wishes to thank Henry Noltie for his dedication and leadership of the Flora ofBhutan project through recent years, and Eona Aitken, Sally Rae, Kim Howell and Norma Gregory for technical and editorial help with this part.
