Although the problem of controlling the spread of exotic invasive plant and animal species in the United States has been recognized for quite some time, it has been lacking an adequate legislative mandate, public awareness, and sufficient funding to meet the challenge. This ACS Symposium Series title showcases the many diverse efforts being made to control invasive species at the federal, state, and local levels. It recognizes the global extent of the problem and compares the methods used in other countries with those of the U.S., and includes recommendations of how best to proceed from here.

Flora of North America, Volume 3, provides information on many of the most familiar wildflowers and trees in North America. Included are treatments of the buttercup family (Ranunculacaeae), with such plants as delphiniums and columbines, and the poppy family (Papveraceae). Most of the important broadleaf tree species are covered, including the oaks (Fagaceae), elms (Ulmaceae), birches (Betulaceae), walnuts (Juglandaceae), plane trees (Plantanaceae), and magnolias (Magnoliaceae). Many striking families are covered, such as the dutchman's pipe family (Aristochiaceae), and the aquatic families Nymphaeceae (water lilies), and Melumbonaceae (lotus).

Identification keys, summaries of habitats and geographic ranges, distribution maps, pertinent synonymies, descriptions, chromosome numbers, phenological information, and other significant biological observations are given for each species. The treatments, written and reviewed by experts throughout the systematic botanical community, are based on original observations of herbarium specimens, and wherever possible, on living plants. These observations are supplemented by critical reviews of the literature.

Sunday Times Bestseller 'A paradigm-smashing chronicle of joyous entanglement' Charles Foster Waterstones Non-Fiction Book of the Month (September) Are trees social beings? How do trees live? Do they feel pain or have awareness of their surroundings? In The Hidden Life of Trees Peter Wohlleben makes the case that the forest is a social network. He draws on groundbreaking scientific discoveries to describe how trees are like human families: tree parents live together with their children, communicate with them, support them as they grow, share nutrients with those who are sick or struggling, and even warn each other of impending dangers. Wohlleben also shares his deep love of woods and forests, explaining the amazing processes of life, death and regeneration he has observed in his woodland. A walk in the woods will never be the same again.

Flora of North America, Volume 22, is the first of five volumes covering monocots in North America, north of Mexico. The volume comprises of many groups of aquatic plants and the North American relatives of groups that have their greatest number of species located in the New World tropics. These include: the rush family (Juncaceae); cat-tails (Typhaceae); spiderworts (Commelinaceae); aroids (Araceae), and pondweeds (Potamogetonaceae). This volume includes thirty families, representing a diverse range of plant forms from marine Zosteraceae (eel-grasses) to stately Arecaceae (palms), and the naturalised exotic Zingiberaceae (gingers), Heliconiaceae (heliconias), and Musaceae (bananas).

In this book Adrian Koopman details the complex relationship between plants, the Zulu language and Zulu culture. Zulu plant names do not just identify plants, they tell us a lot more about the plant, or how it is perceived or used in Zulu culture. For example, the plant name umhlulambazo (what defeats the axe’ tells us that this is a tree with hard, dense wood, and that usondelangange (come closer so I can embrace you) is a tree with large thorns that snag the passer-by. In a similar vein, both umakuphole (let it cool down) and icishamlilo (put out the fire) refer to plants that are used medicinally to treat fevers and inflammations. Plants used as the base of love-charms have names that are particularly colourful, such as unginakile (she has noticed me), uvelabahleke (appear and they smile) and the wonderfully named ungcingci-wafika-umntakwethu (how happy I am that you have arrived, my sweetheart!). And then there are those plant names that are just plain intriguing, if not mystifying: umakhandakansele (the heads of Mr Ratel), isandlasonwabu (hand of a chameleon), intombikayibhinci (the girl does not wear clothes) and ukhuningomile (piece of firewood, I am thirsty).

Andre Laurendeau was the most widely respected French-Canadian nationalist of his generation. The story of his life is to a striking degree also the story of French-Canadian nationalism from the 1930s to the 1960s, that period of massive societal change when Quebec evolved from a traditional to a modern society. The most insightful intellectual voice of the nationalist movement, he was at the tumultuous centre of events as a young separatist in the 1930s; an anti-conscription activist and reform-minded provincial politician in the 1940s; and an influential journalist, editor of the Montreal daily Le Devoir, in the 1950s. At the same time he played an important role in Quebec's cultural life both as a novelist and playwright and as a well-known radio and television personality. In tracing his life story, this biography sheds indispensable light not only on the development of Laurendeau's own nationalist thought, but on his people's continuing struggle to preserve the national values that make them distinct.
