S. RAWAT Summary Nest-site selection by the sympatric Great Hornbill Buceros bicornis, Wreathed Hornbill Aceros undulatus and Oriental Pied Hornbill Anthracoceros albirostris was investigated in a lowland tropical forest in Arunachal Pradesh, north-east India during 1997–2000. Infor- mation on two nests of Rufous-necked Hornbill Aceros nipalensis in higher-elevation forests is also presented. All species nested in live trees of three tree genera, 83% (n = 36) in Tetrameles nudiflora, an emergent deciduous softwood, relatively common in lowland foothill forests. No difference was recorded in nest-tree species or nesting habitats of sympatric hornbills, but there were a few differences in structural characteristics of nest- trees. Cavity size was the main variable separating the three species. Great Hornbills used larger cavities while Oriental Pied Hornbills used smaller cavities closer to riverine areas. Nesting was attempted at 64% of known sites and successful fledging of chicks was 80% overall (n = 72 nests, pooled over 4 years). Nest-trees in disturbed habitats near human habitation were used but were often abandoned or unsuccessful and 50% of all nest-trees were inactive by the end of the study. Potential large nest-trees had a density of 5.9/ha, that of the two most used species was 1.3/ha, and minimum nest densities of all three species was about 1 pair/km2.

KAMRUL HAQUE , SALEH AHAMMAD KHAN, SARDER NASIR UDDIN AND SHAYLA SHARMIN SHETU Department of Botany, Jahangirnagar University, Savar, Dhaka 1342, Bangladesh Keywords: Checklist; Angiosperms; Rajkandi Reserve Forest; Moulvibazar. Abstract This study was carried out to provide the baseline data on the composition and distribution of the angiosperms and to assess their current status in Rajkandi Reserve Forest of Moulvibazar, Bangladesh. The study reports a total of 549 angiosperm species belonging to 123 families, 98 (79.67%) of which consisting of 418 species under 316 genera belong to Magnoliopsida (dicotyledons), and the remaining 25 (20.33%) comprising 132 species of 96 genera to Liliopsida (monocotyledons). Rubiaceae with 30 species is recognized as the largest family in Magnoliopsida followed by Euphorbiaceae with 24 and Fabaceae with 22 species; whereas, in Lilliopsida Poaceae with 32 species is found to be the largest family followed by Cyperaceae and Araceae with 17 and 15 species, respectively. Ficus is found to be the largest genus with 12 species followed by Ipomoea, Cyperus and Dioscorea with five species each. Rajkandi Reserve Forest is dominated by the herbs (284 species) followed by trees (130 species), shrubs (125 species), and lianas (10 species). Woodlands are found to be the most common habitat of angiosperms. A total of 387 species growing in this area are found to be economically useful. 25 species listed in Red Data Book of Bangladesh under different threatened categories are found under Lower Risk (LR) category in this study area.

    Plant Archives Vol. 14 No. 1, 2014 pp. 87-96 ISSN 0972-5210 AN UPDATED ACCOUNT OF THE NAME CHANGES OF THE DICOTYLEDONOUS PLANT SPECIES INCLUDED IN THE VOL: I (1934- 36) & VOL: II (1938) OF “FLORA OF ASSAM” Rajib Lochan Borah Department of Botany, D.H.S.K. College, Dibrugarh - 786 001 (Assam), India. E-mail: [email protected] Abstract Changes in botanical names of flowering plants are an issue which comes up from time to time. While there are valid scientific reasons for such changes, it also creates some difficulties to the floristic workers in the preparation of a new flora. Further, all the important monumental floras of the world have most of the plants included in their old names, which are now regarded as synonyms. In north east India, “Flora of Assam” is an important flora as it includes result of pioneering floristic work on Angiosperms & Gymnosperms in the region. But, in the study of this flora, the same problems of name changes appear before the new researchers. Therefore, an attempt is made here to prepare an updated account of the new names against their old counterpts of the plants included in the first two volumes of the flora, on the basis of recent standard taxonomic literatures. In this, the unresolved & controversial names are not touched & only the confirmed ones are taken into account. In the process new names of 470 (four hundred & seventy) dicotyledonous plant species included in the concerned flora are found out. Key words : Name changes, Flora of Assam, Dicotyledonus plants, floristic works.

A total of 257 species of angiosperms comprising 213 genera and 83 families were recorded from 5.20 sq. kms area, between 90-200m altitudes.
