Studies on the seed viability of Nepenthes khasiana H00k.f. was conducted. Seeds were collected from different natural habitats and stored both at low temperature (5°C) and at ambient room temperature (25 ± 2 °C ) . Seed viability study was carried out by germinating seeds both in vivo and in vitro. For in vivo study seeds were sown on a leaf mold-based mixture in Petri dishes, whereasr in vito, the seeds were inoculated onto half-strength Murashige and Skoog (1962) medium. Within 2 week of culture over 50% of seeds germinated in vitro, whereas in vivo seed germination reached 50% after 8 week. Light and dark conditions were also used to test their effect on gemination. Addition of Gibberelic acid did not show any effect on the gemination of seeds. The study has shown high seed viability as shown from the high rate of gemination, both in vivo and in vitro. For optimum seed germination, high humidity (80 - 90%) and a warm temperature of around 25°C-30°C are essential. The study has also shown that seeds stored at ambient room temperature condition lose its viability rapidly within a year but seeds stored at low temperature (5°C) remain viable for over 5 years.Full Text

During Plant exploration tour to Apatani Plateau, Lower Subansiri district in Arunachal Pradesh in October 2008, an aromatic bamboo was collected by the first author. The plant sample was collected from the hills of 'Luro Poliyang' near Ziro town, the head quarter of Lower Subansiri district. A clump of yellowish green bamboo with long internodes, was spotted, growing inside the subtropical forest at an altitude of c. 1715m. On approaching the bamboo clump, the local guide told that the bamboo's internodes contain clear water which is aromatic and nice for drinking. On cutting one of the bamboo culms, to the suprise it was found as told by the local guide. A single internode contains about 25-50 ml of the sweet aromatic liquid. It was also observed that the freshly cut and split bamboo when kept in a room gives a strong swet aroma for about a week. The plants appear to be rare as there were only a few clumps found in the whole hill during the survey. On close examination along with studies confirmed thatthe plant was reported as endemic to China (Dezhu & Stapleton 2006; Hsueh & Yi 1979). This is the first report from India and hence it is a new distributional record.Full Text
