During the course of a revisionary study on the subtribe Lactuceae in India, the authors encountered some specimens which showed affinities with Lactuca rapuncubides Clarke in the general habit of plant, shape of upper and lower leaves, in the drooping nature of the inflorescence and in having outer involucral bracts much shorter than the inner. Critical examination of these specimens both at BSD and DD, particularly the achene character and the involucre, proved that these specimens belong to a new species, which is described here.- The Flora of the Indian Desert by M.

54 medicinal plants used by the tribals of Balphakram Sanctuary in Meghalaya are reported in this paper. In the enumeration all the speicies are arranged alphabetically and family names and lccal names (Garo names) are also given. Detailed uses of these plants as suggested by the natives are mentioned. It is, however, suggested 'to carry out chemical screening to identify the active principles in these plants before concluding any thing on their uses.- Patfern of Morphological Diversity within Aconitum heterophyllum Wall.

Aconitum heterophyllum exhibits a wide range of inter and intra population variability throughout its natural range of distribution. Three distinct geographical and ecological groups have been recognised within the species which constitute 3 varieties. These are A. heterophyllurn var. heterophyllum, A. heterophyllum var. bracteatum and A. heterophyllum var. roylei. An exhaustive account of the morphologicd variation within the species and a diagnostic key to the varieties with an enumeration have been presented. Each species has been provided with correct name and citation, synonyms, type specimen, distribution, list of specimens examined and notes.- Variation in Podophyllum hexandrum L.

Present study deals with the variation pattern among the populations of Podophyllum hexandrun L. Both intra-as well as inter population variation mainly in hight of plants, length of internodes, length of petioles, leaf incision, margins and pubescence, length of pedicels, colour of flowers, size of fruits and number of seeds have been observed. Some of these variations are continuous and unstable. The variety P. hexandrum var. jaeschkei has been reduced here as synonym under P. hexandrum for the first time.- Design, Development and Validation of Smart Sensor Drifting Node with INSAT Telemetry for Oceanographic Applications

Drifter buoys are globally deployed to measure surface meteorological and oceanographic variables. A Lagrangian drifting buoy (Pradyu II) to measure sea-surface temperature and current has been developed at the National Institute of Ocean Technology, Chennai. The drifter buoy with geostationary satellite communication (INSAT-3C) to have near real-time data at every hour is a unique attempt in the history of drifting buoy nodes. This article describes Pradyu II drifting buoy node, design of low-power embedded system, communication network and field test results from an experiment conducted in the Bay of Bengal during March-April 2013. The results from Pradyu II are compared with commercially available drifting buoy (Marlin-Yug), moored data buoy (BD11) and remotely sensed data.Keywords

Underwater gliders measure high-resolution spatiotemporal oceanographic data. In April 2014, the National Institute of Ocean Technology, Chennai operated an underwater glider ‘Barathi’, for 127 days for observation of Bay of Bengal (BoB). In this article we present the effectiveness of the glider Barathi for high resolution temporal sampling of the surface layer in the central BoB for studying variation of temperature, salinity and density structures and acoustic characteristics on 26–27 May 2014. The results showed ‘afternoon effect’ on acoustic characteristics and formation of secondary sound channel. Our data set is strongly correlated (coefficient of determination r2 > 0.96) with data from a nearby Array for real-time geostrophic Oceanography (Argo) float.Keywords
