Genus Arisaema Martius (1831: 449) is represented by 215 taxa worldwide (Govaerts et al. 2017), of which 61 taxa are reported so far from India including two recent discoveries from Kerala and Tamil Nadu states of Western Ghats, viz. A. peerumedense J. Mathew in Mathew & George (2017: 29), A. madhuanum Nampy & Manudev in Manudev & Nampy (2014: 269) and A. gracilentum Bruggeman (2016: 87) from Arunachal Pradesh of North-East India. During extensive surveys in the Nilgiri Biosphere Reserve, Tamil Nadu, the authors came across two fascinating Arisaema species, one from Thia Shola and the second from Pennant’s Valley forest areas. The first species is attractive by means of its translucent spathe and the latter by its long caudate limb with a filiform thread. Detailed study of relevant literature (Fischer 1933, Fischer 1934, Gusman & Gusman 2002) confirmed their identity as A. translucens Fischer (1933: 344) and A. tuberculatum Fischer (1934: 167), respectively. Arisaema translucens is described by Fischer (1933) based on the collection from Thia Shola forests by E. Barnes at an elevation of 6000 ft made in 1932. From a thorough literature survey and herbarium consultations, it became apparent that this taxon had not been collected since 1932. Hence our discovery is a recollection of this species after a lapse of 84 years from its type locality. Detailed description, colour photographs and distribution information are provided based on the recent collections.

Phylogenetic conservatism or rapid anthropogenic habitat modifications could increase the incidences of interspecific associations of Hanuman and Nilgiri langurs (Family: Cercopithecidae, subfamily: Colobinae) in the southern Western Ghats.  Opportunistic surveys were conducted at the Silent Valley National Park, Kerala and around Devimalai Ghats, Tamil Nadu for  Tufted Grey-Nilgiri Langur association. Based on the observations from Researchers, field assistants, forest staff, and local people, the data in terms of the time of the sighting, number of individuals, phenotypes of individuals, and the time the interaction lasted, were recorded.  The study reports data on a troop of Nilgiri Langurs (N=13) around O Valley tea estate at Devimalai Ghat, Gudalur, Tamil Nadu with some hybrid looking individuals and a Tufted female Grey Langur amongst them. A total of six  and two uni-male troops of Nilgiri Langurs  and grey langurs respectively with Tufted female Grey Langurs, and aberrant coat colored infants observed at the Neelikkal section of Silent Valley National Park are also reported. The study reasonably speculates that there could be more such locations in the southern western ghats and emphasizes the need for more systematic surveys to understand  and explore the ecology, behavior, molecular, and other likely factors contributing to the conservation of vulnerable Nilgiri langur (Semnopithecus johnii) populations.

AbstractThe conservation status of five elephant corridors in different regions of India is discussed. Elephants have not used the 13-km-wide corridor between Ariankavu and Thenmalai, in the southern portion of the Western Ghats for several decades because a rail track and road, both of which are bordered by human habitations, cross it. The future of the Chilla–Motichur and Rajaji–Corbett corridors, which hold the Rajaji–Corbett elephant population in north-west India as one entity, is bleak. It is still possible for elephants to use the Kallar–Jaccanari corridor linking the 4000-strong elephant population of northern and southern Nilgiri Biosphere Reserve in southern India. It may be possible to save the Siju–Rewak corridor, which connects the elephant populations on either side of the River Simsang in north-east India. The authors suggest that other Asian countries that have elephant populations and that are capable of establishing large conservation units, should have master plans that should detail possible developmental activities around existing wildlife habitats. Establishing vast protected areas for large mammals, however, would need political will and regular communication among the nations' development planners, wildlife managers and researchers.

Insight Into

North- East India is an under veiled region with an awe-inspiring landscape, different groups of ethnic people, their culture and heritage. Contemporary writers from this region aspire towards a vision outside the tapered ethnic channel, and they represent a shared history. In their writings, the cultural memory is showcased, and the intensity of feeling overflows the labour of technique and craft. Mamang Dai presents a rare glimpse into the ecology, culture, life of the tribal people and history of the land of the dawn-lit mountains, Arunachal Pradesh, through her novel The Legends of Pensam. The word ‘Pensam’ in the title means ‘in-between’,  but it may also be interpreted as ‘the hidden spaces of the heart’. This is a small world where anything can happen. Being adherents of the animistic faith, the tribes here believe in co-existence with the natural world along with the presence of spirits in their forests and rivers. This paper attempts to draw an insight into the culture and gender of the Arunachalis with special reference to The Legends of Pensam by Mamang Dai.

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.

Abstract:A study of the diversity and distribution of lichens at 10 sites within the Mehao Wildlife Sanctuary in Arunachal Pradesh, India, revealed 177 species, belonging to 71 genera and 35 families. The Sanctuary exhibited almost all the habit and habitat groups of lichens within its climatically heterogenous and altitudinally (400–2700 m) varied landscape. Among the different habitat groups, obligately corticolous lichens were dominant (133 species), followed by facultatively corticolous lichens (occurring on both rock and bark; 25 species), saxicolous lichens (17 species) and terricolous lichens (2 species). The corticolous habitat group was dominated by crustose species while saxicolous and terricolous groups were made up of mostly fruticose species. A substantial number of species (77) occurred at single sites only, and each of the 10 sites supported a distinct lichen assemblage. Altitude and humidity were the putative key factors controlling the diversity and distribution of lichens within the Sanctuary. The mid altitude range 1400–1600 m had the greatest lichen diversity, which showed a unimodal pattern in relation to altitude.
