Ixora Linnaeus (1753: 110) is the third largest genus of the family Rubiaceae with more than 500 species distributed in tropical and subtropical regions of the world (Mouly et al. 2009). The genus Ixora is easily recognized by its articulate petioles, tetramerous flowers, bilobed stigma, uni-ovulate locules and seeds with a large adaxial hilar cavity (De Block 2008). In India, the genus is represented by 47 species (Barbhuiya et al. 2012; Murugan & Prabhu 2014; Karthigeyan & Arisdason 2015). Among of them, Ixora agasthyamalayana Sivadasan & Mohanan (1991: 313), I. beddomei Husain & Paul (1986: 87), I. gamblei Ramachandran & Nair (1988: 220), I. johnsonii Hooker (1897: 139), I. lawsonii Gamble (1920: 247), I. malabarica (Dennstedt 1818: 37) Mabberley (1977: 539), I. manantoddii Husain & Paul (1991: 16), I. mercaraica Husain & Paul (1986: 88), I. monticola Gamble (1920: 246) and I. sivarajiana Pradeep (1997: 315) are endemic to Western Ghats (Singh et al. 2015). During the verification of Ixora species from the Western Ghats of Tamil Nadu, the author found that the name Ixora monticola Gamble (1920: 246) is an later illegitimate homonym of I. monticola (Hiern 1870: 177) Kuntze (1891: 287). Therefore, a new name, Ixora ravikumarii Kottaim., is proposed here as a replacement name for I. monticola Gamble.

Phytosociological study is the most essential in any community to know its structure and organization. The various qualitative characters obtained are used to determine the level of distribution, numerical strength and degree of dominance exhibited by the constituent species in the community. Thalictrum javanicum belongs to the family Ranunculaceae family, it is medium sized erect herb, found in the temperate Himalayas from Kasmir to Sikkim in Khasi hills, and Kodaikanal and Nilgiri hills of Western Ghats in Tamil Nadu, India. At global level, it is generally distributed in the hilly tracts of India, Srilanka, China and Java at the altitude of around 2400 m above msl. The present study was undertaken in Thottabetta , the Nilgiris by sampling using belt transects of 10x1000m size which further divided into 100 segments each which 10x10m size. The total number of species encountered in the study area is 45 which includes 5 grasses and 40 forbs. The quantitative ecological characters of the study species, T. javanicum is a detailed below: frequency 11%, abundance 3.82 individuals/m2, density 0.42 individuals/m2, basal cover 172.20/mm2/ m2, relative frequency 0.55% and relative density 0.08%, relative dominance 0.16%. Based on the ecological attributes it is determined that the species, T. javanicum is less perpetuated in the community studied. Hence, further studies on the determination of propagation strategies for population enhancement and conservationof wilds are suggested.

A new species belonging to the subgenus Isonychia, of the genus Isonychia Eaton, 1871, is described based on larvae and imagoes collected from Moyar River, Nilgiri District, Tamil Nadu, India. The imagoes of I. moyarensis n. sp. can be distinguished from other described Oriental species of Isonychia (Isonychia) by the combination of characters: (i) forewing with rusty brown maculae in the costal, subcostal, and median areas; (ii) femur and tibia brown, fore leg pale, apices of tarsal segments brownish; (iii) males with distal angles of penes rounded, without serrations; (iv) second segment of gonostylus uniformly convex; and (v) sterna of tenth abdominal segment in female deeply cleft. Isonychia (Isonychia) moyarensis n. sp. can be distinguished in the larval stage from other known Oriental species by the following combination of characters: (i) abdominal terga II–IX with median dark brown maculae progressively larger with dark brown slanting streaks in lateral margins; (ii) trachea of abdominal gills I–VII unbranched; (iii) posterolateral projections on abdominal segments I–VII blunt and progressively longer than those of segments VIII–IX, sharp and distinct; and (iv) abdominal terga X pale yellow in anterior ⅓, and dark brown in the posterior ⅔. A key to the known larvae of Oriental species of Isonychia is also provided.

Conrad Hal Waddington was born in Evesham on 8 November 1905. His parents, Hal and Mary Ellen (Warner) Waddington, were of long-established Quaker families and were first cousins, as were Mary Ellen’s parents. His surname traces to the Lancashire village of Waddington. He had one sister— Mrs Doris Christie. His father was a tea planter in South India and he spent his first 2 1/2-3 years on a tea estate in the Wynaad district of the Western Ghats and then nearly two years in Coimbatore, both being in the Madras Presidency (now Tamil Nadu). In a brief autobiographical fragment he describes one of his few memories of India: ‘One morning in the road outside our house I was scuffling my feet in the thick dust; as I remember it, it must have been at least six inches deep. I looked over my shoulder and there was a herd of young domesticated buffaloes coming fast towards me. I was terrified. I fled through the gate into the wide open garden, where the only cover was a rather straggly hedge in which I hid. It was made of some thick juicy plant, whose fleshy leaves were almost indistinguishable from the stem and when I broke one off and, without thinking, put it in my mouth as I watched with relief how the buffaloes went by without noticing me, the white acrid sap stung my tongue sharply, and I felt a renewal of terror that I was now poisoned and would surely die.’ He returned to England at the age of four (though his parents did not return permanently until 1928) to live with an aunt and uncle who had a son of his own age, on a farm in Sedgeberrow in the shadow of Bredon Hill. His uncle was farm manager for a bachelor gentleman farmer, always known as ‘Squire Bowly’, and the family lived with the squire in the farmhouse. His grandmother, who brought up his sister, lived in a house on the outskirts of Evesham where he went on school holidays.

Education has been considered as an indispensable asset of every individual, community and nation today. Indias higher education system is the third largest in the world, after China and the United States (World Bank). Tamil Nadu occupies the first place in terms of possession of higher educational institutions in the private sector in the country with over 46 percent(27) universities, 94 percent(464) professional colleges and 65 percent(383) arts and science colleges(2011). Studies to understand the profile of the entrepreneurs providing higher education either in India or Tamil Nadu were hardly available. This paper attempts to map the demographic profile of the entrepreneurs providing higher education in Arts and Science colleges in Tamil Nadu through an empirical analysis, carried out among 25 entrepreneurs spread across the state. This paper presents a summary of major inferences of the analysis.

Distribution and habitat associations of the Critically Endangered frog Walkerana phrynoderma (Anura: Ranixalidae), with an assessment of potential threats, abundance, and morphology. Little is known about Walkerana phrynoderma, a frog endemic to the Anamalai Hills of the Western Ghats of India. Baseline information (i.e., distribution, threats, habitat characteristics, activity patterns, and relative abundance) is provided for this species, with the aim of improving our understanding of the status of the species in the wild. Visual-encounter, transect, and time-activity budget surveys were conducted in and around the Anamalai Hills of the Western Ghats. The frog skin was swabbed to determine the presence/absence of Batrachochytrium dendrobatidis, and habitat and environmental characteristics were recorded at sites where W. phrynoderma was found. These data were compared with those of sites apparently lacking this species that had suitable habitat. Walkerana phrynoderma is restricted to evergreen forests between 1300 and 1700 m a.s.l. in the Anamalai Tiger Reserve and at Munnar; thus, its range was extended from the state of Tamil Nadu to the adjoining state of Kerala. Pesticide runoff and human disturbance are the most severe threats to the species; B. dendrobatidis was not detected. This nocturnal anuran prefers forest edges and is associated with well-shaded forest foors in cool areas near freshwater streams. Walkerana phrynoderma is rarely encountered whereas its congener, W. leptodactyla, is more common. The impact of anthropogenic disturbances, especially waste disposal and development of tourism infrastructure, should be evaluated. The land that is owned by the Forest Department peripheral to the protected areas could be designated as eco-sensitive sites to prevent changes in land use that could have an adverse effect on W. phrynoderma.

The present article is about the presence of the tv in the society, in general, and its potential as an important agent, such as the family and the school, on the children’s and young people’s development and education. Nowadays we live in a complex world of images with sound, the most of them transmitted by the tv, the cinema and the internet. The infantile universe is full of those images. This way we structured this article in four parts, refering some of the contents related with this subject. The first part describes the presence of the television in the children's daylife and their relationship with the magic box, even the identification that they make with its favourites characters, in order to understand the space that the TV occupies in their lives. The second part presents the different messages transmitted by the television. It is important to analyze the main risks and advantages of television, that is to say, in spite of some programs show bad values, foment the excessive consumption, expose the children to an atmosphere of violence and pornography, also entertains, accompanies, educates, informs, favours the access to the culture and allows to unite the family around a program. At last the third part, this one outlines the necessity to put the tele as a curricular resource in the school, to teaches the students how to analyze, how to criticize and to think about the texts and the news of the world today. The television, considered a powerful tool, is decisive in the communication, such in the formation of values and ideas as in the culture transmission. The function of the school is not to remain far from this factor, but to try to meditate, to understand and to decide its impact, in a better way, on the development of the children and youngs. As conclusion we can add that we’ve tried to aim some strategies that educators and parents will be able to work, united to the children and the youngs, so they could have a new look of the Tv’s world and that they could know how to make their own selection and how to have a critical attitude before the watched product.La presente comunicación se refiere a la presencia de la tele en la sociedad en general y a su potencial como agente importante de formación y educación, junto con la escuela y la familia, en la vida de los niños y de los jóvenes. Actualmente vivimos inmersos en un mundo complejo de imágenes con sonido, que recibimos muy especialmente a través de la tele, del cine y de Internet, los cuales hacen parte del cotidiano del universo infantil. Así, a fin de organizar algunos de los contenidos desde los que es posible enfocar el tema, estructuramos este artículo en cuatro partes. La primera parte describe la presencia de la tele a diario de los niños y su relación con la caja mágica, incluso la identificación que hacen de sus personajes favoritos, a fin de comprender el espacio que ocupa la tele en su cotidianidad. La segunda parte presenta los distintos mensajes transmitidos por la tele. Es importante analizar las principales riesgos y ventajes de la televisión, o sea, a pesar de algunos programas muestran antivalores de la tele: fomentar excesivamente el consumo, exponer a los niños a un ambiente de violencia y pornografía también entretiene, acompaña, educa, informa, favorece el acceso a la cultura y permite unir a la familia en torno a un programa. Cuanto a la tercera parte, plantea la necesidad de incorporar la tele como recurso curricular en la escuela, para que enseñe a los alumnos a analizar crítica y reflexivamente los textos mediáticos. La televisión es considerada como una herramienta poderosa, determinante en la comunicación, tanto en la formación de valores e ideas, como en la transmisión de cultura; la función de la escuela no es permanecer ajena a este factor, pero procurar reflexionar para comprender y decidir mejor su impacto en el desarrollo de los niños y jóvenes. Como conclusión podemos añadir que hemos tratado de apuntar algunas estrategias que educadores y padres podrán trabajar junto con los niños y los jóvenes, para que éstes tengan una nueva mirada del mundo de la tele y para que sepan hacer su propia selección y tener una actitud crítica ante el producto visionado.

During the taxonomic revision of the genus Osbeckia Linnaeus (1753: 345) from the Western Ghats, India, we came across few interesting specimens from the Manjolai hills in Kalakkad Mundanthurai Tiger Reserve (KMTR), Tirunelveli, Tamil Nadu. Critical studies with relevant literature revealed the identity of the collected specimens as Osbeckia tirunelvelica Manickam & Murugan (2001: 626). Unfortunately the name Osbeckia tirunelvelica was not validly published by Manickam & Murugan (2001), because, contrary to Art. 40 of ICN (McNeill et al. 2012), two collections were indicated as “type”. Therefore, the name Osbeckia tirunelvelica is validated here by indicating a single collection as the holotype.

Impatiens megamalayana, a new species from Tamil Nadu, India is described and illustrated. This species is characterized by a ridged stem, ensiform and villous leaves, a wrinkled boat-shaped lower sepal with outwardly curved tip, ornamented seeds and strictly ovate pollen grains. This combination of characters makes determining the relationships of I. megamalayana difficult. The floral structure of I. megamalayana is closely allied to I. herbicola Hook.f. and I. inconspicua Benth. in Wall., the latter with three varieties, but it differs by several unique vegetative and floral features. Impatiens megamalayana is assessed as Critically Endangered in accordance with the IUCN guidelines. The habitat of the species is severely affected by landslides. As a result, effective strategies should be developed to protect I. megamalayana from exinction.
