A total of 122 species under 56 genera and 32 families were recorded from Itanagar Wildlife Sanctuary, Arunachal Pradesh during 2008-2009. Among these 29 families, 53 genera, 118 species are ferns, while 3 families, 3 genera and 4 species belong to fern allies. Polypodiaceae with 20 species, Pteridaceae with 19 species and Thelypteridaceae with 15 species were among the dominant families.
We studied the anti-inflammatory activity of a petroleum ether extract of Phyllanthus singampattiana. Sebastine and A.N. Henry leaves, which was tested in Wistar rats with TPA-induced ear inflammation and carrageenan-induced paw edema. Carrageenan-induced paw edema was significantly reduced at a dose of 100 mg petroleum ether extract (p < 0.05%). From the crude extract, β.-sitosterol was identified and confirmed.
With the passing away of Rev. Father Dr. Visuvasam Sousai Manickam, Pteridology in India has lost one of its great stalwarts. Father Manickam died on the 30*^ March 2012 at St. Mary's Higher Secondary School, Madurai, bringing to an end a life of 68 years spent in spiritual quest and in the pursuit of Pteridology.Born on l""* June 1944, in the small village of Kamalapuram, Dindigul District of Tamil Nadu, as one of several children, the second son of Visuvasam Paripooranam. After his local school studies he joined the Society of Jesus at Beschi College, Dindigul, in 1961 and studied religion for two years. He then went to Chennai to pursue his college studies and was ordained as a priest at Loyola College, Madras (as Chennai then was] in 1964-1967. He chose an undergraduate course in Botany at Loyola College, which he passed with a high mark and then went on to do a postgraduate course in Botany at St. Joseph's College, Tiruchirappalli (Trichy], earning a first class degree through his dedication and attention to detail.Following this and his awakening interest in Botanical studies, he was awarded a Ph.D. in Botany in 1975 at the University of Kerala, Thiruvanantapuram (Trivandrum), which he joined in 1971. He studied there under the guidance of Professor C. A. Ninan, in the school of the late Professor A. Abraham, to learn fern cytology. It was under Prof. Ninan's stimulating supervision that he developed his ground-breaking research studying the cytology of South Indian ferns and carried out extensive detailed fieldwork on the Pteridophytes of the Western Ghats from 1969 onwards. He was able to explore the entire Palni Hill range, surveying and collecting some 2500
Arbuscular mycorrhizal (AM) colonization and spore density of the two endemic plants growing in the natural forests were determined. Variations in spore number and colonization rate were observed in both the plants. The most frequent fungi present in the rhizosphere were also different. The AM colonization and sporulation were influenced by pH and phosphorous content of the soil.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
