The present paper deals with the investigation of moss taxa of some underexplored regions of Manipur, Northeast India. During the assessment of moss diversity in various localities of Manipur a total 126 species of mosses belonging to 84 genera in 34 families have been investigated and enumerated. Ten species, namely Amblystegium serpens,Entodontopsis leucostega, Entodontopsis tavoyensis, Homalia trichomanoides, Lindbergia duthiei, Philonotis mollis, Philonotis thwaitesii, Taxiphyllum giraldii,Tortella humilis and Thuidium sparsifolium are new additions to Eastern Himalaya, while 92 species of mosses have been reported for the first time from Manipur. Ten Indian endemic taxa have also been identified from the explored sites. The majority of the taxa were recorded from epiphytic habitats.

The paper deals with eight taxa of lichens from the district of Darjeeling, Eastern Himalaya, India. Of the taxa described, Tomasellia himalayensis, Phlyctella indica, Placopsis himalayensis, Bombyliospora laevigata, and Rinodina conradi var. megaspora are new to science; Tomasellia cinchonarum and Haematomma leprarioides are reported for the first time from the Indian subcontinent; and Haematomma wattii endemic in the Eastern Himalaya is critically examined.

Globba wengeri (C.E.C. Fisch.) K.J. Williams, former state flower of Mizoram, a rare and critically endangered plant species, commonly known as ‘dancing girl’, belonging to the family Zingiberaceae, is reported in this communication for the first time from Serchhip District in Mizoram at an elevation of about 1187 m a.s.l. It was found on moist, watery and rocky slopes. The plant is under severe threat in the natural habitat and therefore, further studies are required to determine life history and particular survival threats of this species.

High Seismicity

abstract Practically the whole of northeastern India and northern Burma is characterized as an anomalous gravity field as well as an area of high seismicity. The Bouguer anomaly in the region varies from +44 mgals over Shillong Plateau to −255 mgals near North Lakhimpur in Assam Valley. Isostatic anomaly (Hayford) varies from +100 to −130 mgals in these areas. Over Arakan-Yoma and the Burmese plains, the isostatic anomalies vary from −20 mgals to −100 mgals. Regions of high seismicity in the area include the eastern Himalaya (including Assam syntaxis), Arakan-Yoma including the folded belt of Tripura, Irrawaddy basin, Shillong Plateau, Dauki fault and the northern part of Bengal basin. The abnormal gravity and seismicity are related to large scale tectonic movements that have taken place in the area mostly during the Cretaceous and Cenozoic times, due to interaction of the Indian, Tibetan, and Burmese plates. The high seismicity indicates that the movements are continuing. The seismic zone underlying Burma is approximately V shaped and dips toward the east underneath Arakan-Yoma. Most of the intermediate-focus earthquakes in Burma underlie the area characterized by negative isostatic anomalies, indicating the probable existence of a subduction zone underneath the Arakan-Yoma and the Burmese plains. The Shillong Plateau has a history of vertical uplift since Cretaceous times. Provided this statement is true, the uplift of the plateau preceded Himalayan tectonics starting 20 to 30 m.y. before continental India made solid contact with the Eurasian plate. The plateau is characterized by large positive isostatic anomalies as well as high seismicity. The positive isostatic anomalies may be due to intrusion or incorporation of basic material from the mantle into the crust underlying the Plateau. These intrusions may have taken place through deep seated faults such as the Dauki and could be responsible for its uplift as well.

The present paper documents the genus Anemone L. (Ranunculaceae) from India. A total of 26 taxa (which includes 24 species, one subspecies and one variety) has been recorded from Indo Himalayas. Western Himalaya is endowed with 9 taxa, Eastern Himalaya with 8 taxa, while 9 are common to both the flanks. Three species are present in Northeast India which are common to IHR and one species has also been reported from Western Ghats. This genus constitutes flowering plants of high altitude and maximum diversity has been observed between 2000–3000 m asl. The genus possesses high medicinal potential and needs urgent assessment of taxonomic and conservation status for its sustainable utilization.
