These efforts, coming through cooperation with our friends at the Royal Botanic Gardens, Kew, are a gift to humanity and contradict those who advocate death to our beloved country. In general, this part covers eleven plant families from Elatinaceae to Sphenocleaceae, and not only gives information about these plant families in Iraq that will facilitate work of researchers both within and outside our country, but it is also an important step in the completion of the exploration phase for investigating plant diversity in Iraq, which will pave the way in the future for developing important strategies, plans and projects to protect our threatened plant species, and regulate the sustainable exploitation of this natural wealth. I would like to extend my sincere thanks to all those who have contributed to this work, and also express my gratitude to the Royal Botanic Gardens Kew and the staff of the National Herbarium of Iraq for their great efforts to complete this volume of the Flora.

Melzheimer, Philipps University, Marburg, Germany Alex Sukhorukhov, Moscow State University, Russia Cliff C. Townsend, Royal Botanic Gardens, Kew, UK The present instalment of the Flora of Iraq contains treatments of eleven families traditionally regarded as members of the Centrospermae (and now largely placed in the core Caryophyllales). In Hutchinson’s system they comprise three orders: Caryophyllales, Polygonales and Chenopodiales. The families are the Aizoaceae, Amaranthaceae, Caryophyllaceae, Chenopodiaceae, Theligonaceae (Cynocrambaceae), Elatinaceae, Illecebraceae, Molluginaceae, Polygonaceae, Portulacaceae and Sphenocleaceae. Although our understanding of family relationships has advanced considerably since the scheme of the Flora was drawn up we have retained the traditional format as set out in vol. 2, pp. 8–14. The family Elatinaceae is now placed in the order Malpighiales and the Sphenocleaceae is placed in the Solanales following the APGIII system. The family Chenopodiaceae in now subsumed within the Amaranthaceae, the Theligonaceae (Cynocrambaceae) within Rubiaceae, and the Illecebraceae within Caryophyllaceae, but, apart from the Illecebraceae, these are kept separate here. The editors are pleased to present the work of external contributors of taxonomic accounts to the present volume in addition to Kew staff who were responsible for writing parts of this volume some thirty years ago. The completion of this project will be increasingly dependent on such assistance, since with the exception of vol. 6 (Asteraceae/Compositae) which is already completed and awaiting final editing, many of the accounts of the remaining unpublished families are still unwritten. Since the publication of vol. 5 part 2 we have seen further steady progress with the Flora of Iran (in Persian), and the first volume of a new Flora of Turkey (in Turkish) has appeared. Though no further volumes of the Flora of the Arabian Peninsula & Socotra have become available, the collections in the herbarium of the Edinburgh Royal Botanic Garden provide good coverage of the countries lying to the south of Iraq. An increasing number of specimen images are now available for consultation online from several European herbaria, making the job of establishing overall distributions considerably easier. In several treatments, notably in the Chenopodiaceae, a fairly radical revision to generic limits has been made in the light of new research. The genus Salsola, in particular, has an altered circumscription and there are many nomenclatural changes and even a few newly defined genera. The large genus Silene (Caryophyllaceae) has been prepared by separate authors for its annual and perennial species, and in the Polygonaceae the genera Polygonum and Persicaria are now separated. Because of the order in which this work was completed, vol. 5 contains separate indexes to its two parts. Our aim is to provide illustrations of at least one species in each genus, and in order to do so we have been granted permission to reproduce drawings from other Floras to complement those which were specially commissioned for this work. A few small adjustments in the spellings of collection sites have been made in the light of further work on the Gazetteer, but we have tried to ensure that transliterations from Arabic script continue to follow the system set out in vol. 1. Kurdish place-names are more difficult to interpret, not only because of the state of flux in these areas but also because the increased adoption of the Roman script has not yet been accompanied by any overarching process of standardisation. As for vol. 5 part 2, we have had the full support of colleagues and staff from the National Herbarium, Abu Ghraib, Baghdad, for which we are most grateful, and feel encouraged that beyond the completion of this Flora taxonomic research will still carry on there.
