This is the first full account of the higher plants of northern Yemen. It includes descriptions of all the species known from the region with keys for their identification. More than 40 plants are illustrated in colour and others by line drawings. In addition there are sections on the history of botanical exploration, phytogeography and the ecology and distribution of vegetation types. Appendices include lists of Arabic plant names and poisonous plants together with a gazetteer of localities.

This 2001 book provides a selective annotated bibliography of the principal floras and related works of inventory for vascular plants. The second edition was completely updated and expanded to take into account the substantial literature of the late twentieth century, and features a more fully developed review of the history of floristic documentation. The works covered are principally specialist publications such as floras, checklists, distribution atlases, systematic iconographies and enumerations or catalogues, although a relatively few more popularly oriented books are also included. The Guide is organised in ten geographical divisions, with these successively divided into regions and units, each of which is prefaced with a historical review of floristic studies. In addition to the bibliography, the book includes general chapters on botanical bibliography, the history of floras, and general principles and current trends, plus an appendix on bibliographic searching, a lexicon of serial abbreviations, and author and geographical indexes.

A small and extremely poor Islamic country, Yemen is located on the edge of the Arab world in the southernmost corner of the Arabian Peninsula. It was the product of the unification of the Yemen Arab Republic and the People's Democratic Republic of Yemen in May 1990. The location of the two Yemens on the world's busiest sea-lane at the southern end of the Red Sea where Asia almost meets Africa gave them strategic significance from the start of the age of imperialism through the Cold War. More vital today is the fact that Yemen shares a long border with oil-rich Saudi Arabia and is a key to efforts both to spread and to end global revolutionary Islam and its use of terror. The second edition of the Historical Dictionary of Yemen has been thoroughly updated and greatly expanded. Through its list of acronyms and abbreviations, a chronology, an introductory essay, a bibliography, and over 800 cross-referenced dictionary entries, greater attention has been given to foreign affairs, economic institutions and policies, social issues, religion, and politics.

An exploration of how plant behavior and adaptation offer valuable insights for human thriving. We know that plants are important. They maintain the atmosphere by absorbing carbon dioxide and producing oxygen. They nourish other living organisms and supply psychological benefits to humans as well, improving our moods and beautifying the landscape around us. But plants don’t just passively provide. They also take action. Beronda L. Montgomery explores the vigorous, creative lives of organisms often treated as static and predictable. In fact, plants are masters of adaptation. They “know” what and who they are, and they use this knowledge to make a way in the world. Plants experience a kind of sensation that does not require eyes or ears. They distinguish kin, friend, and foe, and they are able to respond to ecological competition despite lacking the capacity of fight-or-flight. Plants are even capable of transformative behaviors that allow them to maximize their chances of survival in a dynamic and sometimes unfriendly environment. Lessons from Plants enters into the depth of botanic experience and shows how we might improve human society by better appreciating not just what plants give us but also how they achieve their own purposes. What would it mean to learn from these organisms, to become more aware of our environments and to adapt to our own worlds by calling on perception and awareness? Montgomery’s meditative study puts before us a question with the power to reframe the way we live: What would a plant do?

This book is designed to provide pharmacologists and researchers of natural products a comprehensive review of 200 medicinal plants, their vernacular names in various languages and their medicinal uses around the world, and in some cases, a historical perspective. Chemical constituents of each plant with the putative active constituent, and available up to date pharmacological studies (until 2017 on PubMed) with each medical activity explored and its relationship with traditional uses, are described for each plant. Any variations in chemical constituents and their effects on pharmacological studies outcome have been highlighted. All clinical trials conducted, with sufficient details, have been included. Nationalities and racial identities of participants of clinical trials are identified to impress upon the social, cultural and dietary influences on the clinical outcomes. Toxicity studies and potential interactions with prescribed drugs, and full spectrum of references are included.

The inspiration for this book came from our ten years of journeys and wanderings through the varied landscapes of Arabia, and in particular through those of its hospitable southeastern corner, Oman. We owe a particular debt to Sultan Qaboos University, which during this time has provided us with both a stimulating working environment and a home. Transliteration of Arabic place and other names into English script is a task fraught with difficulties. We have followed 'accepted' spellings wherever these were not contrary to our common sense, and in other cases we have rendered names into Roman English script using phonetic spellings. Our main task in this respect was to ensure conformity between the fIfteen contributing authors. Diacritical signs have mostly been avoided, since their use is neither widely followed nor readily understood. Arabic words which have been commonly taken into the English language, such as 'sabkha' for a salt flat and 'wadi' for a valley with a seasonal watercourse, are not italicised in usage. However, other Arabic terms which are occasionally used in English but not as widely known, such as harrah for a basaltic lava fIeld and hima for a traditional grazing reserve, are italicised throughout the text.
