Orchids are one of the most wondrous creations of nature, which provide a never-ending source of unique plants with an extremely wide range of flower shapes, colors, fragrances, and sizes. orchids are most popularly used as ornamental plants for their flowers or for brilliantly decorative foliage incase of jewel orchid group but, in addition they have various other uses also like curing various diseases and in health care. The family Orchidaceae is one of the oldest known and the largest family of flowering plants in the world but still it is one of the least known mainly die to its discouraging high number of species and their wide distribution. Estimated between 25000 to 30000 species with over 800 genera, they are found in almost every nook and corner of this globe. In India the orchid family is the second largest family of flowering plants and is represented by about 178 genera and 1280 species. Though orchids in India are cosmopolitan in distribution their maximum number and diversity is found in the Himalayas, North Eastern region and Western Ghats. The Western Himalayan region supports a rich orchid flora comprising of more than 270 species of which the state of Uttarakhand or the west Himalaya alone harbors about 239 species. The book A Century of West Himalayan Orchids deals with 100 interesting and unusual species of orchids. The introductory chapters provides a brief but lucid account of the history of orchidology including the first reported orchid fossil, detailed vegetative and flower structure of orchids excellently supported by relevant colour photogrpahs.

Hardcover. Zustand: As New. Contents: Preface. Index to figures. 1. Taxonomic treatment. 2. Lady's slipper orchids of India. 3. References. Index. Lady's Slipper or Slipper Orchids are an extremely well known group of orchids. They are popularly called Lady's slippers because of the presence of a highly modified pouch-like lip or labellum, which looks similar to a lady's slipper. They are highly priced and much sought after in the floriculture industry as potted plants as well as cut flowers due to their enchantingly attractive, colourfull blooms and ability to remain fresh for several weeks. The presently known five lady's slipper orchid genera, which belong to the orchid subfamily Cypripedioideae are widely distributed in the temperate regions of Eurasia and North America, Central America south to Brazil and Bolivia, tropical Asia from India across to Taiwan, south-east Asia from Indo-China across to the Philippines, New Guinea, and the Solomon Islands. In India, only two genera namely Cypripedium and Paphiopedilum are found, which are confined to the Himalayan and North-East Indian region except one species of Paphiopedilum P. Druryi, which is endemic to Western Ghats. The book is the first ever comprehensive taxonomic treatment of Indian Slipper orchids. In the introductory part of the book, a brief history of lady's slipper orchids, their taxonomy and a glimpse of all the five known genera of this group has been provided. The main part of the text comprises of the detailed taxonomic information on the 14 species of lady's slippers (Cypripedium-5 and Paphiopedilum-9) reported from India. The descriptions for all the species have been drawn from the live plants along with colour plates made from fresh flowers for the first time for these orchids. In addition, in some cases the interesting history of their discovery and collection (wherever available) has also been appended. This apart, in some of the species, type specimens were wrongly designated and quoted and were followed till date by the orchid taxonomists and monographers. Such wrong treatments have been corrected through lectotypification by designating appropriate Lactotypes. No other serious reference approaches the depth and authority of this remarkable book. Plant taxonomists, Nature lovers and those who just initiated the study of orchids will appreciate and value this book for identification and taxonomic information with regard to Lady's slipper orchids.

Hardcover. Zustand: New. 1st Edition. From the introduction: "In India orchids are known to occur from Andaman and Nicobar Islands to Himalayas, the maximum number of species are however concentrated in the North-Eastern region where excessive rainfall coupled with warm humid climate and tropical evergreen forests offer the most congenial conditions for orchid growth. Sathish Kumar and Manilal (1994) have reported a total of 166 genera and 1141 species from India of which North-Eastern region alone accounts for more than 700 species. "There are about 1000 genera and more than 17000 species of orchids widely distributed from tropical to alpine regions of the world and the family Orchidaceae (Monocotyledons) is one of the largest families of the flowering plants. Orchids have amazing ability of hybridization. Ever since the release of first man made orchid hybrid- Calanthe Dominyi, as back as in 1856, a large number of orchid hybrids have been produced through hybridization between different species of a genus, or between different genera. Today more than 80,000 orchid hybrids are known and more and more are being registered every day.".
