Sustainable City around Indian Alpine Wetland: A Case of Mirik Lake, West Bengal

Abstract

The high-altitude lake systems of the Himalayas in Kashmir and Ladakh have unique variations in their water chemistry and fauna and flora.

Didymocarpus phuquocensis, a new species of Gesneriaceae from Phu Quoc Island, South-western Vietnam

“…Morphologically, the 3-verticillate petiolate leaves of D. phuquocensis are shared with several species of Didymocarpus , such as D. insulsus Craib (north-eastern, Thailand), D. tristis Craib (Chanthaburi Province, south-eastern Thailand), D. dongrakensis B.L.Burtt (northeast Thailand) D. newmanii B.L.Burtt (Chanthaburi Province, south-eastern Thailand), D. pulcher (from India, Buhtan, Nepal, China to Vietnam), D. hookeri (Assam, Arunachal Pradesh, Meghalaya and Sikkim, India), D. punduanus (Assam, Meghalaya and Nagaland, India) ( Wang et al 1998 ; Nangngam and Maxwell 2013 ; Phuong et al 2014 ; Sinha and Datta 2016 ; Roy 2017 ). Of these, the campanulate calyx of the new species is similar to D. pulcher , D. hookeri and D. punduanus , but distinguished from D. insulsus , D. newmanii and D. tristis which have the calyx 5-lobed to the base.…”

“…A critical examination of living flowers, herbarium specimens of these plants and comparison with type material and protologues of all closely-related species in Vietnam and neighbouring countries (e.g. Clarke 1874 , 1883 , 1884 ; Wallich 1829 ; Wang et al 1998 ; Pham 2000 ; Nangngam and Maxwell 2013 ; Phuong et al 2014 ; Nangngam and Middleton 2014 ; Sinha and Datta 2016 ; Roy 2017 ), suggested that these specimens were different from the other known Didymocarpus species. These plants with 3-verticillate, petiolate leaves, campanulate calyx, funnelform corolla found in Phu Quoc NP show similarities in these characters with D. pulcher , D. hookeri C.B.Clarke and D. punduanus Wall.…”
