A PRELIMINARY CHECKLIST OF ANGIOSPERMIC FLORA OF Bangladesh J. Plant Taxon. 12(2): 85-96, 2005 (December) A CHECKLIST OF ANGIOSPERMIC FLORA OF LALMAI HILLS, COMILLA, BANGLADESH MD. MUNIR HOSSAIN, MD. ABUL HASSAN AND MOHAMMAD ZASHIM UDDIN Department of Botany, University of Dhaka, Dhaka-1000, Bangladesh Key words: Preliminary checklist, angiospermic flora, Lalmai hills, Comilla, Bangladesh Abstract The paper includes a checklist containing a total of 151 angiospermic species (127 dicot and 24 monocot) growing in the Lalmai hills, Comilla, Bangladesh, which has been prepared after the survey of the area during the years 2001 and 2002. Introduction The Lalmai hills are situated in the district of Comilla, about 8 km to the west of Comilla town. They lie on 23°-21′ N latitude and 91°-09′ E longitude. The hills are commonly known as Mainamati - Lalmai range. The range includes 50 hillocks (Hossen and Dewan 2004). The range extends from north to south for a distance of 17.71 km from Mainamati to Datya Dighi and is about 40.25 km in circumference. The area of investigation consists of several hills of different heights and a few valleys. The hills attain a height of 45 m at some places, but the average elevation is 12 m above the plains. The highest peaks are Kalir Bazar and Chand Mura, and there are small springs near these peaks and Bijaynagar. The hills are bounded by the faults on the western and eastern sides. The faults scrap on the east is up-thrown to the west and considerably dissected by drainage channels. On the west there are two parallel faults about 1.5 km apart of which both are up-thrown on the east. The inner fault forms a well- defined valley, while the outer (westernmost) fault has a surface throw in excess of 30 m at several places. Structurally this range is a horst, tilted to the east. The hills are flat with steep and strongly gullied sides, mainly consisting of unconsolidated sands with a clay capping. The old piedmont apron comprises a narrow fringe of foothills along with the Chittagong-Tripura hills in India with a gently flooding relief. It also comprises the foothills of Lalmai hills, mainly consisting of unconsolidated finer textured and moderately well-drained soils derived from weathered Tertiary or Pleistocene unconsolidated sands and soils. These strongly acid soils occur on gently rolling areas of the Lalmai hills. They have yellowish-brown topsoil overlying a strong brown to yellowish-red structured clay subsoil. Texture of the surface layer varies from sandy-clay-loam to clay-loam. These soils are moderately well-drained with medium to rapid runoff and medium internal drainage, which are droughty in the dry season. The forest enjoys a tropical climate characterized by a period of high precipitation from May to October and six months of relatively dry period from November to April. The Lalmai supports a moist deciduous Sal forest. It supports a large number of plant species that would contribute to the forest economy of Bangladesh. But the forest of 86 HOSSAIN et al. Lalmai hills area does not have any published flora or manual. At the same time this area is vulnerable and needs to be documented and protected immediately. Materials and Methods The present work is based mainly on the fresh materials collected by the authors from the study area through repeated field trips during the year 2001-2002. These are supplemented by the herbarium specimens examined at the Dhaka University Herbarium and Bangladesh National Herbarium. The identification of the specimens was confirmed with the help of Hooker (1872-1897), Prain (1903, 1903a), Brandis (1906), Kanjilal et al. (1934, 1938, 1939, 1940), Khan (1977, 1984, 1985), Deb (1981, 1983) and Matthew (1999, 1999a, 1999b). The families have been arranged according to Cronquist (1981). The genera and species under each family are arranged in alphabetical order. The checklist includes wild, naturalized and planted species. Results A total of 149 species under 127 genera and 49 families have been identified and recorded in this paper. Magnoliopsida is represented by 43 families, 108 genera and 127 species while Liliopsida is represented by 6 families, 19 genera and 22 species. In Magnoliopsida, the Fabaceae appears to be the largest family having 9 genera and 12 species. In Liliopsida, the Poaceae appears to be the largest family having 8 genera and 11 species.
