We report the presence of this species for the first time from Sandur forests in Bellary district, Karnataka based on a voucher specimen and from Gulbarga township based on sighting record. A detailed distribution map showing localities from where the species is known is also provided.

Alagesaboopathi / Journal of Pharmacy Research 2012,5(10),5039-5042 Research Article Available online through ISSN: 0974-6943 http://jprsolutions.info Poisonous Plants of the Salem District of Tamilnadu, Southern India C. Alagesaboopathi Department of Botany, Government Arts College (Autonomous), Salem – 636007, Tamilnadu, India Received on:12-06-2012; Revised on: 17-07-2012; Accepted on:26-08-2012 ABSTRACT The present investigation was carried out in the Salem district of Tamilnadu, India, to document the poisonous plants. A total of 33 species belonging to 28 genera and 20 families have been reported. Information on poisonous plants is significant as some of them are used in medication. The poisonous activities due to toxic substances namely, tannins, glycosides, saponins, alkaloids, amines, proteins, amino acids, mycotoxins, picrotoxins, resins, chelating poisons, etc. a record of 33 poisonous plants occurring on the Salem district of Tamilnadu has been presented. The knowledge on the poisonous plant species has been collected from the tribals, village dwellers, the herbal medicine practitioners and other traditional healers during ethnomedicinal field survey. The poisonous plant species are arranged in alphabetical order. Each plant is followed by its family, vernacular name (Tamil), poisonous plant part(s) and poisonous symptoms. The investigation recommends that tribals and common people are not only knowing of such poisonous plants and their detrimental causes, but also utilize them judiciously for manage of mosquitoes, bugs, ticks, grasshoppers, moth, insect-pests and several other hurtful organisms. Key words: Poisonous plants, Ethnomedicine, Malayali, Salem, Tamilnadu.

Endangered Species of India — the Higher IUCN Categories Christopher Roy Fraser-Jenkins Student Guest House, Thamel. P.O. Box no. 5555, Kathmandu, Nepal E-mail: [email protected] (Received 19 July 2012; accepted 26 September 2012) Abstract A revised list of 337 pteridophytes from political India is presented according to the six higher IUCN categories, and following on from the wider list of Chandra et al. (2008). This is nearly one third of the total c. 1100 species of indigenous Pteridophytes present in India. Endemics in the list are noted and carefully revised distributions are given for each species along with their estimated IUCN category. A slightly modified update of the classification by Fraser-Jenkins (2010a) is used. Phanerophlebiopsis balansae (Christ) Fraser-Jenk. et Baishya and Azolla filiculoi- des Lam. subsp. cristata (Kaulf.) Fraser-Jenk., are new combinations. Key words : endangered, India, IUCN categories, pteridophytes. The total number of pteridophyte species pres- gered), VU (Vulnerable) and NT (Near threat- ent in India is c. 1100 and of these 337 taxa are ened), whereas Chandra et al.’s list was a more considered to be threatened or endangered preliminary one which did not set out to follow (nearly one third of the total). It should be the IUCN categories until more information realised that IUCN listing (IUCN, 2010) is became available. The IUCN categories given organised by countries and the global rarity and here apply to political India only. -

Ethnobotanical Studies on Some Rare and Endemic Floristic Elements of Eastern Ghats-Hill Ranges of South East Asia, India Dowlathabad Muralidhara Rao and Thammineni Pullaiah Department of Botany (SKU Herbarium), Sri Krishnadevara University, Anantapur. 515003 [email protected] WWW.SKUNIVERSITY.ORG Issued 24 May 2007 ABSTRACT The Eastern Ghats, one of the nine Floristic Zones in India. Eastern Ghats are spread over three States of India, namely Orissa, Andhra Pradesh and Tamil Nadu. The hilly areas of Eastern Ghats in Andhra Pradesh are mainly inhabited by 33 aboriginal/tribal communities, who still practice the age old traditional medicines and their application. There are 62 different tribes, inhabited in Orissa. The inhabitants of the aboriginal tribal communities, who still practice the age old traditional medicines and their applications. The author undertook ethno medicobotanical studies in Eastern Ghats along with systematic survey. Many tribal people depending on naturally growing or wild plants for their food and medicine in this region. The study during 1997-2005 brought to light, many unknown uses of plants which are interesting has been collected by the author. The present paper deals with some rare and endemic plant ethnobotanical uses of Eastern Ghats. Key words: Eastern Ghats, Ethnobotany, Rareplants, Endemic plants. INTRODUCTION The Eastern Ghats are located between 11° 31' and 22° N latitude and 76° 50' and 86° 30' E longitude in a North-East to South-West strike. The Ghats cover an area of about 75,000 Sq.

We have been extracting energy, materials and organisms from nature and altering landscapes at a rate that cannot be a sustainable one. Our nature is an essential partnership; an 'essential', because each living species has its space and role', and performs an activity vital to the whole; a 'partnership', because the biological species or the living components of nature can only thrive together, because together they create a dynamic equilibrium. Nature is further a dynamic entity that never remains the same- that changes, that adjusts, that evolves; 'equilibrium', that is in spirit, balanced and harmonious. Nature, in fact, promotes evolution, radiation and diversity. The current biodiversity is an inherited vital resource to us, which needs to be carefully conserved for our future generations as it holds the key to the progress in agriculture, aquaculture, clothing, food, medicine and numerous other fields.
