Sankaran, present Director, Kerala Forest Research Institute, Peechi and Research Co ordinator, Dr. K. Swarupanandan for their keen interest, encouragement and for the facilities. I wish to thank the Directors and Curators of different major Indian herberia, like, Central National Herbarium Calcutta (CAL); Forest Research Institute herbarium, Dehra Dun (DD); BSI Southern circle Coimbatore (MH); Andaman & Nicobar circle Port Blair (PBL); BSI Western circle Pune (BSI), Sikkim Himalayan circle, Gangtok (BHC); Northern circle, Dehra Dun (BSD); Calicut University (CALI) and Kerala Forest Research Institute Herbarium (KFRI) for permitting me to study and critically examine all the required herbarium specimens deposited in the respective herbaria. I express my sincere thanks and gratitude to Mr. K. Sasidharan Nair, IFS, PCCF, Kerala; Mr. G. P. Shukla, IFS, PCCF, Andaman & Nicobar Circle; Mr. C. Amhaluna Laha, IFS, CF, Andaman & Nicobar, Mr. R. S. C. Jayaraj, IFS, Silviculture Division, Andaman & Nicobar Circle, for all the help rendered and for the permission and organisation of our field trip during the stay at Andamans. Thanks are also due to Mr. Dileep D' souza and Mr. Ajayakumar, Range Officers, who had taken lot of pains for accompanying us during the field trips and for their help in the field. Sincere thanks are due to Dr. J. F. Veldkamp. National Herbarium Nederland, Universiteit Leiden branch, for providing his expert comments and clarification with regards to certain bamboo species during the study.

K F R I ABSTRACT India is endowed with a large number of bamboo species and is perhaps having the world's one of the largest resources of bamboos. Due to the non-availability of flowers and irregular flowering phenomenon, the species identified by earlier workers have posed several problems with regard to the correct identity of the species. It has been observed that many of the workers have neglected the geo-climatic variations as a result of which several generic and specific delimitations among the Indian bamboos are confusing, it is also noted that most of the genera described by earlier workers have been treated congeneric with one taxon or the other. Therefore, the reports on the number of taxa occurring in the respective localities considerably vary. There are over 1575 species under 111 genera (Ohrnberger, 1999) of bamboos distributed in the tropical, subtropical and temperate regions of the world. In India, so far, 128 species belonging to 18 genera are known to occur. They are distributed mainly in the geographic zones such as, Western Himalayas, Eastern Himalayas including Northeast India, Peninsular India and Andaman and Nicobar Islands. Peninsular India is one of the richest domiciles of native bamboos, second to the Eastern regions. So far, 32 species and two varieties spread over eight genera are known to occur in the region. Of these, 22 species and two varieties belonging to six genera, namely Bambusa, Dendrocalamus, Ochlandra, Oxytenanthera, Schizostachyum and Sinarundinaria are native to Kerala. In the present study detailed taxonomic account of the genera, Dendrocalamus, Oxytenanthera, Schizostachyum and Sinarundinaria is provided. Some of the salient findings of the study are the following; one species is added to the genus Dendrocalamus as a new combination Dendrocalamus stocksii, formerly known under Oxytenanthera- Pseudoxytenanthera complex. The lectotypification of Dendrocalamus stocksii, D. colletianus, D. callostachyus and D. longispathus, and neotypication of D. stictus, the type species of the genus, have been carried out. Some of the species under Dendrocalamus such as, D. sahinii, and D. somdevai are treated as conspecific with D. hamiltonii and therefore synonymised under it. Dendrocalamus sericeus is also conspecific with D. strictus. The genus Pseudoxytenanthera is synonimised under Oxytenanthera with two species, O. bourdillonii and O. monodelpha. The lectotypification of O. bourdilonii has been carried out. The generic status of Schizostachyum has been critically examined and three species from Andaman iii
