As stated many times before the purpose of Orchid Biology, Reviews and Perspectives (OB) is to present reviews on all aspects of orchids. The aim is not to balance every volume, but to make a balanced and wide ranging presentation of orchids in the series as a whole. The chapters in this, the last volume of the series, range over a number of topics which were not covered before. Singapore is justly famed for its orchids. They can be seen on arrival (or dep- ture) in its modern, highly efficient and comfortable Changi Airport and on the way from it to town. Vanda Miss Joaquim, the first hybrid to come from Singapore became its National Flower. This natural hybrid can be seen on its currency, stamps, and public and private decorations. Many excellent breeders, starting with Prof. Eric Holttum who bred the first man made hybrid (Spathoglottis Primrose), produced numerous magnificent hybrids and won countless awards in Singapore and elsewhere. These hybrids served to enrich the country’s orchid mystique. In the opening chapter of this volume Dr. Teoh Eng Soon (Western style: Eng Soon Teoh), himself a prize winning orchid breeder, grower and author writes about some of the breeders who contributed to the Singapore orchid fame. Prof. Hans Fitting was one of the best known plant physiologists of his time. As a young man he studied the effects of pollen on orchid flowers.

The Himalaya has profoundly shaped the cultures of the Indian subcontinent, with many Himalayan peaks considered sacred in Hinduism and Buddhism. Some of the world's major rivers – the Indus, the Ganges and the Brahmaputra rise in the Himalayas. These rivers have abundant seasonal and annual water supply. The mountain ranges and river basins share trans-boundary connectedness. Still, mountain people living on hills have limited access to water for drinking and agriculture. Covering around 27% of the Earth’s land surface, the mountains contribute to the sustenance and wellbeing of over half the human population for water, food, and clean energy. Yet mountains are under threat from climate change, land degradation, overexploitation, and natural disasters, with potentially far-reaching and devastating consequences, both for mountain communities and downstream populations. The book covers interdisciplinary domains of science, humanities and commerce, hence beneficial for all types of readers equally. Promotion of awareness and education on conservation and sustainable utilization of bioresources and strengthening networks, coordination with the help of central government departments, state governments, NGOs and local institutions is urgently needed.

This book is an up-to-date checklist of the current valid taxonomyfor all vascular plants, bryophytes, and lichens in British Columbia,including synonyms, species codes, and other information. A convenient,geographically restricted, comprehensive checklist like this one willaid greatly in avoiding the present confusion concerning the names ofmany species in the ecological and systematic literature, as well as inapplied fields. The book is organized into three sections. Part 1 organizes speciesalphabetically according to taxonomic order by families of vascularplants, bryophytes, and lichens. Within each family, the genera arelisted alphabetically, along with any synonomies (former names) andcommon names. In Part 2 species are organized alphabetically accordingto their scientific names. Part 3 lists common names followed by theirscientific names. Excluded names (names inappropriately applied toplants in B.C.) are given in an appendix. Those familiar with planttaxonomy will find Part 1 particularly helpful when checkingnomenclature; semi-professionals familiar with scientific names willuse Part 2 and then Part 1; those who know only common names will checkPart 3 and then Part 2 and Part 1 to determine families. There is presently considerable confusion about many species namesin B.C. Plant names change for many reasons and new plants invade.Information about plants in B.C. is scattered in several checklists,most of them incomplete or out of date; for some species, such asliverworts, no provincial checklist even exists. This checklisttherefore will be useful to all professionals working with vegetationand for students in agriculture, botany, ecology, forestry and othersciences. Although the focus is on B.C., the book will also be usefuloutside the province, particularly in the northwest American states andin Alberta and the Yukon.
