Ladys' Slipper Orchids of India. 2015. 100 col. pls. XIII, 164 p. gr8vo. Hardcover.

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 ladys slipper orchids, their taxonomy and a glimpse of all the five known genera of this group has been provided. The main partof the text comprises of the detailed taxonomic information on the 14 species of ladys 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 Lectotypes.
