Varför mins- kar den? Hur ser läget ut i landet? Skiljer det sig åt i olika delar? Även om jag är lite sent ute på året, tror jag ni har i färskt minne hur det ser ut på era mosippelokaler. Skicka in uppgifter till oss, rapportblan- kett finns att skriva ut från vår hemsida. Om ni inte har till- gång till den, ta gärna kontakt med Staffan Åström, mig eller Linda på kansliet så skickar vi en blankett (se pärmens insida för adresser). Vi hoppas kunna publicera resultatet av de inkomna uppgifterna i en artikel i SBT. För att kunna vara en stark och inflytelserik förening och för att kunna ge ut vår fina tidskrift är det viktigt att vi är många medlemmar. Under större delen av 1990-talet minskade antalet medlemmar ganska mycket, men under de tre senaste åren har vi sakta men säkert börjat öka medlemsantalet igen. Passa på när ni är ute i olika sammanhang att sprida kunskap om vår förening till era botanikvänner, som ni tror skulle kunna vara intresserade av att bli medlemmar. ”De vilda blommornas dag” firades runtom i hela vårt avlånga land den 9 juni. Jag vill redan nu framföra mitt och föreningens TACK till Dig och alla andra som på olika sätt medverkat i arbetet med att genomföra denna dag. Jag återkommer till ”De vilda blommornas dag” i nästa nummer. Ha en skön sommar!

ISSN: 0973-9467 © East Himalayan Society for Spermatophyte Taxonomy doi:10.26679/Pleione.13.2.2019.305-316 Enumeration of Flowering Plants of Senchal Wildlife Sanctuary, West Bengal, India Ajay Ghosh and T. K. Paul1 3/1, P.K. RoychowdhuryIst bye Lane, Howrah – 711103 1Corresponding author: E-mail: [email protected] [Received 16.11.2019; Revised & accepted 24.12.2019; Published 31.12.2019] Abstract In the present communication 226 Angiosperm species have been recorded from the Senchal wildlife sanctuary in the Darjeeling district, West Bengal. Out of theses, 19 species have been found to be medicinally important. Key words: Flowering plants, Senchal wildlife sanctuary, Darjeeling. INTRODUCTION The Senchal Wildlife Sanctuary, located in Darjeeling district of West Bengal, India, covers an area of 38.6 sq km. The Sanctuary lies approximately 26°31´ – 27°13´ N latitude and 87°59´ – 88°53´ E longitude and spreading over an elevational gradient of 1500 – 2600 m. ‘Senchal’ means ‘The Hill of Damp and Mist’ and so the sanctuary was named as “Senchal Wildlife Sanctuary”. It is one of the oldest wildlife sanctuaries of India and set up in 1915. The core area of the Sanctuary remains cold throughout the year. The day temperature varies from 5°C – 15°C. July and August are the monsoon months in the area. The core area of the sanctuary receives 2500 – 3000 mm of annual rainfall. This huge amount of water drains out through the fountains and slopes from the hilly part of the Sanctuary finally to Teesta River on the east part and to Balason river on the west.

  • ABSTRACT Fan, Chuanzhu. Molecular
    ABSTRACT Fan, Chuanzhu. Molecular Phylogeny and Evolution of Dogwoods. (Under the direction of Dr. Jenny Qiu-Yun Xiang) Dogwoods consist of morphologically diverse plants, and taxonomic circumscription and phylogenetic relationships of dogwoods have long been controversial. My dissertation study has two major goals: 1) elucidate phylogenetic relationships in the dogwoods group using nuclear DNA sequences, and 2) investigate the sequence evolution and its morphological link of the myc-like anthocyanin regulatory gene and explore the phylogenetic utility of the gene in dogwoods. Phylogenetic relationships within Cornus and Cornales (Cornus and related genera and families) were previously investigated using chloroplast DNA sequence data in several studies, but these still remained incompletely resolved. I used nuclear 26S rDNA sequences to further elucidate relationships within the group and to corroborate previously published phylogenetic hypotheses based on cpDNA and morphological data. Phylogenetic analyses of 26S rDNA sequence data (~3.4 kb) in combination with sequences of chloroplast genes rbcL and matK, suggest that the aquatic enigmatic genus, Hydrostachys from southern Africa, is sister to the remainder of Cornales among which Cornus and Alangium are sisters, nyssoids (Nyssa, Camptotheca, and Davidia) and mastixioids (Mastixia and Diplopanax) are sisters, and Hydrangeaceae and Loasaceae are sisters. These relationships, except the placement of Hydrostachys, are consistent with previous findings from analyses of matK-rbcL sequence data. Within Cornus, the dwarf dogwoods (subg. Arctocrania) are the sister of the big-bracted dogwoods (subg. Cynoxylon and subg. Syncarpea). This clade is, in turn, sister to the cornelian cherries (subg. Cornus and subg. Afrocrania). This large red-fruited clade is sister to a clade consisting of the blue- or white-fruited species (subg.
