Zingiberaceae are the largest of the Zingiberales and members are found primarily in the tropics and subtropics with the centre of diversity in the Indo-Malayan region. Amomum Roxb. s.l. is the second largest genus after Alpinia in the Ginger family with about 150-180 species distributed widely in Southeast Asia. In India, they are occurring mainly in Northeast, Peninsular and the Andaman-Nicobar Islands. Amomum s.l. include many economically important plants likeA. subulatum, A. maximum, M. aculeata etc. A. subulatum, ‘large cardamom’ is one of the major cash crops of India and is one of the ingredients for avor and fragrance in the food and perfumery industries. Andaman aborigines useM. aculeata for tranquillizing rock bees and harvesting honey. Fruits ofA. maximumare used as a vegetable. Amomum s.l. in India is represented by three genera viz. Amomum, Meistera and Wurfbainia. The revision identied 35 taxa of Amomum s.l. from India which include 15 spp. of Amomum s.s. with a variety of A. raoii and 5 cultivars of A. subulatum, 12 ssp. of Meistera and 2 spp. of Wurfbainia. The investigation revealed that 17 species of Amomum s.l. are endemic to India. The authors described 21 taxa New to Science from India and ndings were published in reputed journals. The book includes the details of rediscoveries, new records, new synonyms and typication of taxa from India. The introductory part begins with a brief account of the family and genera followed by various aspects related to the genera like Taxonomy and Floristics, Indian scenario, Phylogeny, Pollination Biology, Embryology, Palynology, Anatomy, Cytology, Phytochemistry, Agronomy, Pathology, Capsule curing, Ethnobotany, Uses, Spice, Medicine, Antibacterial activity, G enetic variability, Micropropagation, etc. This is followed by the detailed classication, comparative morphology and systematic treatment. systematic part begins with citations of Amomum s.l. and is followed by a brief description of the genera.
